Conors 172 Cup track toy build..

Hi everybody,

So I am back and properly in action this time. I posted last year in July about starting to do a few bits on my 172 Cup, but that never materialised. This time it's for real and I wait until I had some bits done before starting to post here. The July post contains some real "warts and all" shots of the car in it's state at the beginning of Feb.

The car currently has most of the interior stripped, bumpers and lights off...

What I want from this is: Further convert the car into a novelty "race car" with race car like features etc, without going complete competition spec. The intention is that this will be road legal and track friendly but not MSA legal, i.e. I won't be competing in it. I'm not doing any of the mods to slim down track times, but more for a coolness factor and to make it easier to work on in the future.

Why I want this: Why not!? Just for novelty, learning and also the car needs a bit of tidying up as it's a bit rough after the many track days in a previous life.

Planned work / Mods:
  • I had started to list items but it was becoming a bit long... typical refurb really.
The work so far:

(DAY 1)


I found a nice place to work, with a few other projects yet to be started :) Day 1 saw me unloading the tools and getting acquainted with my new second home :)

20210206_122210.jpg


During the moving process the bumper had to be removed as it had mostly fallen off anyway :LOL:

20210206_131159.jpg


Starting off with a few good tools but lacking in some areas.. i'll be sure to have double the amount by the end of this..


20210206_131207.jpg


After removing the seats, I managed to single-handedly get the half cage out. You can see in the photo where I strapped the exposed ends.. this helped with visualising the shape and kept the ends from splaying outwards. By all accounts, this is supposed to be an awful job. I'm not sure what made it so easy for me.. perhaps the fact it's only a small enough unit.

Day 2 update - the point of no return!

After my first day working on the car, my back was nearly broken. Bending down to pickup various tools was so frustrating and tiring. I picked up this Halfords Advanced tool trolley and it's a god send. £288 with trade card wasn't bad either.

20210213_123219.jpg


I also noticed a couple of leaks while the car was stood for the week. The left hand side is steering, which I knew was leaking.. and prompted this overhaul. Not quite sure what the second is..

20210213_123939.jpg


This is a documentary photo, so I can remember how the door is fixed. This pin was a pain to remove. I ended up hammering with a punch. Not ideal, but I needed to get the doors off as they were a major nuisance. One got slightly bent and I can order new ones if needed. Also will probably need the tool to re-install.

20210213_130529.jpg


Doors finally off.. no more opening and closing to get around..

20210213_133914.jpg


So this photo represents the "point of no return" for me. I ended up ripping out and breaking a few fixtures on the upper dash, as it was very stuck on the left side. I will be able to install new mount points when re-installing so not too worried.

The lower dash was also very difficult to get out. For some reason I couldn't get access to the middle area holding the radio / control. So I just hammered my way through it all. I knew it wasn't going to be re-installed anyway so wasn't bothered. One slight concern is the ducting for air. I plan on keeping the heater matrix in there to provide heat if needed. I will probably remove the directional venting and just have fixed cabin heater controlled by a "high, low, off" toggle switch.

Question: Does anybody know if the rusted brown metal bars are required for safety here.. or are they just for structural integrity of the dash? I see them removed in a lot of "race cars" but perhaps this is ok because they have full roll cages? As I don't have a full cage, must I leave the bars here?

20210213_172433.jpg


So I introduced a slight crack in the windscreen when removing the rear view mirror.. it was always going to happen as I didn't even use much force really. The windscreen seemed super fragile, which makes be believe the Cup screen is actually lighter. I hit it a thump for good measure later on to see it spider a bit more :shame

20210213_172441.jpg


Excluding the roll cage, this photo represents a whole days work. Man the interior took a lot longer than anticipated. Still the rest of dash wiring and loom to remove.

Day 3

Today I wanted to label all the wiring loom before moving forward while the connections were still fresh in my mind. I plan on breaking down the loom and removing any un-needed wires. I don't think I will replace any wiring unless warranted.

On one hand, I think I should make a completely new loom, because the car is 19 years old. On the other hand, I can just strip out the unused wiring and re-use, to save cost. Keeping in mind that the dash will be stripped and it will be much easier to get to the loom in future if problems arise. Thoughts?

20210214_104428.jpg


The rear bumper bolts were a real bar steward to remove. The sprung captive nuts, or whatever you call them were seized on and I couldn't get a proper grip of them. I needed to grind them off with little space so it was a little brute force. I will need to tidy up those fittings before the bumper goes back on. I imagine a new piece spot welded on and drilled should do the trick. I have never welded anything before but I plan on grabbing somebody nearby to show me through this project.

Should really have used my Dremel for this, but it was at home.. great place for it!!

20210214_121724.jpg

20210214_125826.jpg


Next up were the side skirts.. these have rivets in place of screws so needed to be drilled out.. Re installing them will probably be the first time I use a riveter too.. Did I say I was doing this project to learn some things along the way? :)

20210214_125902.jpg

20210214_125826.jpg


The bolts for the skirts were seized on too, and needed to be ground off. Another place for the Dremel. The bolt glowed red and melted the surrounding skirt.. Well that is sure to make some people cringe. I am sure that is also easily fixed later on too.

Great stuff, must be nice to have a proper space to work and not in the street or a narrow drive!

Also Im not sure on that support bar but I know it supports the column with a couple bolts as the mk2 column brackets are made of cheese.

And those couple bolts in the arches, I didnt think they would need that much to get them off, I would of thought they would just snap if you turned them with some mole grips!

ClioSport Club Member
Well yes, in hindsight you are correct. I will also need to drill out the screw also. Oh well.. this is all a learning curve.

Part of me is kind of excited about all the possible problems so I get to learn how to fix them :)
 
I see this project escalating quickly. I told myself with my clio that it would be a weekend car with good pads and tyres to take it to track days. Its now in pieces undergoing a full track car build. It seems youre going in the similar direction haha

Totally.. it's already escalated, a lot!

So in November I set about removing the steering rack for a refurb. Noticed the suspension/subframe rust... I then spent the proceeding months looking for a space.

And now we are here.... stripping the car back to single metal shell to rebuild as mint.

I need to do some planning once I get the car apart and see what I can spend money on, but I envisage about £2.5/£3k should get me over the the line with a decent not competition build.

Big expense will be new coilovers if needed, although can very easily be added later on, on my drive.

I also want to look into power management too... I read somewhere that somebody used the UCH in modified form, instead of a dedicated (expensive) PDU.

One thing people don't seem to talk about on here is money... I once asked how much something cost and felt weird.

I think on this thread I might talk about money. Costs, budget etc. It will help give people an idea of what a build costs and where the could save / add cost.

I mean for the most part people know how much parts cost minus the nut and bolts builds plus they probably don’t wanna come across as billy big balls shouting about how much they spent on their old french car, it’s not a great look. I guess its all about spending money in the right areas, ive purposely upgraded parts in my car slowly over the years, one not to loose interest, two to stop being moaned at and three to save cost, for instance my wet/road wheels are still the ones I was given when I bought the car, I could replace them for something that looks nicer/abit lighter but they do the job so haven’t bothered as yet.


Over the 5 years ive owned my track car its hard to think how much its cost me tbh, not sure I want to add up the receipts and its not even an amazing build, just a generally fairly tidy track hack and it doesn’t even have a diff (yet) :( Car aside each track day costs best part of £300 including the fuel/garage/food etc, best not to think about it and just enjoy yourself and just worry when you run out of real money lol.

I couldn't agree more.. My build will be no where near the top end. Just a couple grand and a lot spent on refurbing/restoring. While people know the rough cost of bits, once you have a lot of stuff together it's anybodys guess as to the final build.

I suppose my thinking was that people will see what you get for the money on a straightforward build. Perhaps I'll just offer to ping over details privately if people are interested in cost. I just wanted to help and not overcompensate for other shortcomings lol.

Day 3 - Rear subframe removal

Today I dropped the rear subframe. Made a bit of a mess of it really, as I got the balance of the frame wrong, so when I released it from the car it rotated around the point on the jack, as seen in the pics.

Took out this mounting bar that holds all the trim together. Will probably cut it down before putting back so as to hold the instrument cluster and dash top.

20210220_083306.jpg

20210220_091500.jpg


Went about taking off the wings next, and noticed this fairly rotten looking brake servo.. Probably would have taken a while to noticed that.


20210220_085218.jpg


Wipers up next.. rather crudely yanked them off... I'll be able to tidy up before putting back on but if you value your wipers you should buy the correct tool imho.

20210220_094004.jpg


20210220_104002.jpg


These subframe bolts were a pain, I don't quite understand the fittings they were using. They just gave way after a few ugga duggas. I muscled through most of them with the vice grips, but had to grind off the final one. I'll have to figure out how to refit them later without those crappy brackets. Curious how others refit rear subframes.

Are you using your Turini’s as axle stands??

I sure am.. I will admit it feels fairly shameful, but when the rear was on stands the didn't sit right and you could kind of rock the car so I opted for the safer option.

They were in rough enough shape anyway so will need a refurb, and actually not getting damaged from the car really..

Hahha because it’s a sure way to a depression once you start talking about money. My original budget of 8k was exceeded 3 years ago. I stoped counting after that.

Yea, fair point. I actually realised I was going to stop bean counting once I did some back of envelop estimations in Excel.

Much better off to just work away on the car and spend as needed.. keep your head firmly in the sand or clouds, whichever you favour :)

Genuine lol. You'd spent £8k on parts before you even bolted anything on it.

Alright guys..

Sorry for the radio silence here. I got a bit bogged down with a bunch of stuff and also found the stripping of the car a little monotonous and didn't think people would care for it lol. I have an album online if somebody is interested let me know.

In the meantime, here is a whirlwind update of where I am now.

In the unit I am renting.. another guy is building this temp spray booth. I'm waiting to see how it shapes out.. I may see if I can get in to spray the Clio. For colour I am thinking of Purple base, black (or bronze) wheels and yellow trim, such as calipers and a couple other bits. That colour looks great on the 911 GT3 RS .. Not sure it will be amazing on the Clio. Ultimately I don't think anything is amazing on the Clio, as deep down I really don't like the shape, but then again it does make an amazing track car - so says the internet, which is why I bought it :D

That insulation ain't going back in.. thankfully. It became apparent after removing what was left of the sound deadening that the car will be even louder than it was before... thankfully it will be predominantly track and the odd blast around public roads. No daily'ing or anything mental like that.

20210306_121318-jpg.jpg



Basic :)

20210306_165222-jpg.jpg


Where is the grimace emoji. I plan on stripping out the un-needed bits and building a new version of what's left. I will re-use the connectors.

20210306_165234-jpg.jpg


Engine out :). I don't plan any mods on this. It's got 122k miles on it. I will do the famous belt and dephaser service while it's out, and after that wait for it to blow before opening it up.

I've built up a makeshift table where I can keep stuff up off the ground and do a few of the smaller jobs on it.

This rear beam is very much toast. It's getting media blasted along with the calipers.

That Anti Roll Bar is toast really.. It's proving awkward to get here in Ireland and postage from UK is a pain. I'll tidy this up and re-install it. It's an easy change later on. This is one of the Cup specific parts on this car. It's a bit thicker than other models.

20210402_144734-jpg.jpg


The rear brakes are totally rusted. These have been cleaned up in citric acid. I guess part of the reason is that there is near zero brake effort on the Cup models as there is no ABS. These discs have no noticeable lip on them and I am loathe to replace them if the same will happen again. It's about £160 for the pair as they come with bearings pre-installed.


20210327_153802-jpg.jpg


They came up like new. If you ignore that oxide lol.

The two front jacking points took a bit of hassle from axle stands... My fault really. Some advice says that I can easily fold these back with a vice grips. I secretly want to cut these out and weld in some nice little sections that I can sit onto my axle stands. I need to investigate but something a little shaped to fit the stand and some rubber pads bolted on. I've not seen them anywhere so I am not sure who great an idea it is, but would be very practical.

I started cleaning down the underside of the chassis. No water being used.

First off was white spirits but that is oil based and doesn't dry too well so I have moved over to paint thinners. The thinners is great and is helping me remove the Schutz.. It doesn't seem to be too great up around the engine bay with all the grime. First pass will be thinners but I have purchased two gallons of brake cleaner and will give another clean with that. After some testing if it doesn't work to satisfaction, i'll use degreaser and rinse off with a spray gun - certainly no power washer.

Alrighty then.. another update.

Great weekend. So I feel like I covered a nice bit over the weekend, and for brownie points I got to change the oil on my E class :)

TLDR; - Cleaned up the underbody, discovered a rotten section. Painted some parts. Checked alternator brushes.


Alternator / Engine. I plan on refurbing the externals of this and changing the timing belt and "dephaser" pulley. Extracting the alternator to check brush length and see if they need renewal. I don't want them to run out and see me left on the side of the road. Have you ever heard of anybody proactively renewing the brushes on their alternator? I haven't, but it's beggars belief.

20210417_121239-jpg.jpg


Brushes look good to me.. plenty of life left in them I think... or is there?

20210417_121246-jpg.jpg


Sprayed some de-rusted parts with primer on Saturday and black on Sunday. Hanging from the brake lines out of the car lol.. they are being replaced btw ;)

I just like this picture.. My space has grown quite a bit since day 1.. bit messy this pic and I plan on tidying next day out.

20210417_165704-jpg.jpg


I also dismantled the rear brake compensator. It's supposed to be factory set for the Cup variants. I need to do some research on this. I don't fancy it going back in and I would like to investigate two options.

1. Removing it altogether and just installing a brake bias valve inside the car. This would serve a useful purpose in that I could crank up the rear bias for MOTs as tester often erroneously fail these cars due to lack of rear brake effort. So much so that the VOSA had to issue a bulletin for it, specifically for this model.
2. Re-install the above valve inside the car as the brake lines will be internal. Obviously omitting the spring mechanism as I believe that does nothing on the Cups anyway.
whatsapp-image-2021-04-18-at-17-34-43-jpeg.jpg


Upon inspection of some "file footage" this is it in situ, warts and all. Looks like the lever isn't connected to anything and as such the spring wouldn't move anyway. Therefore, the bias is predetermined and can't be affected by the travel on the rear beam.. To be continued.

On Sunday I spent some time really getting into it with the underside of the body. Having recently queried how to clean up the nooks and crannies, I am delighted to announce I found the perfect tool. I had picked up a set of these Rolson Mini Brushes before for a couple quid and the nylon works really well. Please note that while these work well, a of the Rolson line up is not good at all, imo and I would not recommend them to anybody. I have also decided never to buy Rolson again.

I also found that using a can of brake cleaner or my spray bottle pressured up is good for then blasting out the agitated dirt.

1618860487813-png.png

I didn't get a picture of the cleaned underbody as phone died, but I will post next time I get one.

In the mean time, please see this hole I found!!

...What hole!?

20210418_113914-jpg.jpg

20210418_115619-jpg.jpg


This hole!!!

I think it has originated from the excessive jacking/support on that corner on the seams, which seems to have caused rot that crept in under the under seal. With that in mind, I will be inspecting the other corners too.

It doesn't seem that bad really and I am somewhat excited about it as it means I get to learn about that repair process. Now I will say this - It appears structural and as such I won't be doing the welding for the repair, having never welded before. I had always been thinking of adding some sill reinforcement for easy jacking/support. Given this will be a track car, it's going to get a lot more of that action than a normal daily driver.



20210418_152020-jpg.jpg


I have 4 of these type of stands so it stands to reason I could build something that will accept these easily. I am thinking about a piece of slightly profiled steel plate with some rubber plates fixed on. In my head it would be quite tidy.


1618860878163-png.png


The other alternative is to buy some of these rally stands which should sit onto the axle stands. I feel less comfortable with that though, they will be visible from exterior also.

So this evening I started work on the rewiring. Starting with the rear loom as it's the smallest.

Baby steps..

First step is to identify all the connectors, pins and wires and then match them up in the wiring diagram I have.

Once I am comfortable with that, I will:
* Strip down any covering on the loom.
* Identify the wires I don't need and remove them
* decide on a colour scheme for the wires. I'm not going down the rainbow route.
* copy the loom by cutting out new lengths of wire and coding them to be similar to the existing loom.

Before actually cutting I will likely need to make some decisions about where I am putting the fuse boxes/ecu/etc. ECU and engine fuses are currently in the engine bay, I plan on putting them into the area that would previously have been the glovebox/dash area.

20210422_135822.jpg


.. And I spent a while identifying all the connectors on this loom, using a wiring diagram I got online. The diagram refers to the X65 Clio II platform, and includes stuff such as A/C and ABS, which are not in my car.. So I need to be very careful.

The reason I am using this diagram as it's easy to understand. I need to be very cautious for the dash and engine looms. I'll be sourcing another set of diagrams to cross reference and double check against.

On this loom, I think I will be using everything and not binning anything.

..Another weekend, another update (Actually the previous weekend, I did nothing :/)

Had a nice long weekend to get back on track as the previous weekend I did nothing at all.


So the biggest rust issue is around the 4 jacking points that were all mashed from previous misuse. One of the corners is very bad and the three remaining ones aren't so bad but will need some car. I spent a lot of time over the weekend pulling them apart to examine the extent of the rust. I think 3 of them won't need cutting/welding, but just a clean up with grinder, rust treatment and then some plying back together and some spot welds to keep them, followed by seam sealer..

The fourth seam needs some cutting and fabrication as you will see. These pics show as far as I got. You will see I probably need to cut more, but not sure to what extend. The guys working around me say I have nearly cut too much and just need to basically "tack" it back together... if I do anything else I am only making work for myself.

Two things on this -

a) I am doing this to learn and for fun. Doing is fun for me.
b) This is a track car, I don't want to compromise strength or rigidity, because time.

I'd love to hear what you would do with the repair.

So this pic sums it up the best I think. You can see there are multiple skins here. One of them I seem to have cut back a bit too far.

What I am thinking is to weld on some sheet to each skin to extend the length then form them back into the same shape as before and spot weld them together like they did in factory. Probably run some multiple spots along the top where the three edges are exposed.

One of the other ideas presented to me was to put this stuff back together best effort without massive amounts of fab, then just create a new sheet to the overall profile of the sill/seams etc and weld it over the top, providing security. I'm not sure about that.

I really don't want any rust remaining.. part of me feels like I need to cut back a lot more to actually make it easier to repair. I feel like by cutting back only minimal bits it's far to tricky to get in there to weld small bits on here and there.

From watching videos online, it seems that most places cut back so that only simple shapes are being welded back in.

What do people think?

I almost forgot to post some more bits..

I continued cleaning down the body and this weekend focused on the downward facing sections of the engine bay and also a front wheel well. I need to spend plenty of time cleaning this up as there is plenty of crud in tight spaces and if not removed, the paint won't stick - and look AWFUL!

Started work on cleaning up the engine too...

I don't plan on taking the head off or messing with the valve train, but I will overhaul everything else. Part of the job was to remove the PAS pump as I am going electric on this. Water pump came off too and will be replaced, as will the cam belt and the famous dephaser pulley. Crank pulley looks knackered too, so will probably be replaced.

No matter how hard I try.. there is always spillage, so I keep a bunch of cat litter nearby which is super stuff! €1.80 in Tesco for a bag, can't go wrong!

Found this in the oil pickup.. the wire gauze doing it's job - I don't feel worried about this, should I be? Looks like a bit of sealant or something :/

Right lads.. another small update.

At the weekend I spent a bunch of hours cleaning up the top surfaces of the engine bay + one of the wheel wells. It's actually mental how long it takes to do a good job. Using a combination of that small toothbrush like tool, small wire pick and brake cleaner + white spirits. I think it will pay dividends come spray time though. I probably spent too long on the downward facing surfaces but I am aiming for a full covering of paint and I really dont want to see paint coming away from the various nooks and crannies due to oil residue, if I can help it. A certain amount will be guaranteed as I am not vapour blasting the entire shell, but it should be good enough..... "It's only a track car, right!?"

Here a few pics of the work in progress.. it's super rewarding to see how it scrubs up. I particularly like cleaning the seam sealer which has lots of grime caked in. My method seemed work really well which was.. spray some white spirits, agitate/scrub with brush then shoot it all off with pressure of brake cleaner in hand sprayer. You can see the results below.

Side note: You might have recalled a previous question about how I would clean the car. I am just about finished with the cleaning, including removing all the schultz from underside. I think I have used about 4 litres of brake cleaner + 4 litres of white spirits. No water! That doesn't seem bad. I thin there is probably a lot of silicon in the white spirits so i'll probably have to splurge on a gallon of silicon remover to use before paint. Does anybody know if that is really needed or if thinners is ok?

You will note the corrosion there too. Which again, all things considered, does not seem bad at all. Will be treated in due course.

One thing I found peculiar though, was that on both sides the corners towards the bottom/front of the wheel arches were bashed in. Is it a coincidence it happened on both sides, or was this some kind of steering or wheel clearance kind of "mod"? I'm going with coincidence and multiple bumps where the bumper would have bounced but the metal not so much. Who knows. I pulled one out and will do the other again.

Looks like the outer edges are all bashed in too.

What do you think?

I also cleaned up around the fuel tank filler, and this will need some TLC also. It's a well known rust point on this car. Mine isn't actually too bad, all things considered.

20210509_163837-jpg.jpg



Still doesn't seem like much to look at which seems a bit mental, considering I have completed my 27th day of working on the car. I do feel as though I am progressing though.

It is easy to be hard on ones self when it comes to assessing progress but I don't mind if an experienced person would have gotten here in half the time. Before April 2019, I had never even used a socket on a spanner before so I don't think i'm doing too bad in the grand scheme of things lol.

Oh.. in looking at the photo here is a fun tidbit... see the black brackets all along the sill where the outer sill would sit. I took them off by drilling the rivets out.. now the inner rivet part is inside the sill and i'm not sure how I will get them out.. If they remain they will just rattle around in the car - FML.

...and here comes the interesting part.

Just as a reminder, this is where I left off last time... It's all a bit flimsy and crap looking, so I reckon it just had to go..

All hail the sharpie, eh!?

20210508_132538-jpg.jpg



I ended up with this after much strategic grinding, cutting and wire wheeling..

20210508_165237-jpg.jpg



If you look right into the centre of this photo, where the floor pan meets the front and side skins, you will see it's still a little crusty here. The collet in my dremel started acting up so I couldn't tighten a stone into it, that will get cleaned up next time..

This photo also shows that the inner most vertical skin is gone pretty thin in one or two places due to the rust. There is still the smallest amount of corrosion seeping in behind where the floor pan joins on.

I simply cannot clean this out without having to cut into the floor pan and creep upwards with a power tool to cut out more of the vertical surface? Is that worth doing?

Something really really irks me about the thought of leaving even the smallest amount of untreated (preferably cut out) rust in the car, especially an area that will be covered up by welded metal. What would you do?

20210508_165238-jpg.jpg



The jury is still out on these remaining outermost bits. They will remain for now, but sometimes I look at them and feel like they should go. I would probably feel a lot more comfortable with new bits welded in.

20210508_165308-jpg.jpg



Freshly cleaned metal is a sight to behold, isn't it. Until you revisit it the next day.. when it's got surface rust on it. That leads me to my next topic - my paint system. I will create a separate post for that.

Paint system!? - I'm clueless!!

So guys..... etch primer, high build primer, epoxy primer, 1k, 2k, water based, oil based, base coat, clear coat, porous, non porous, reaction, orange peel, keyed surface, flash off, under seal, seam sealer, schultz .. the list goes on.

If you ask me about any one of these terms in isolation I can probably give you the full lowdown, or a pretty solid attempt. But when it comes to coming up with a formula I don't have the confidence to pick the best combination.

Let's start off with the bare metal. I've reached a point now where I have started cleaning metal surfaces with my knotted wire wheel and when left, surface rust re-appears.

My initial plan to prep any metal surfaces is to use:

* Grinder with knotted wire cup/wheel for most of the rust
* Bilt Hamer Deox Gel (Rust remover) and Hydrate 80 (Rust converter) to chemically remove/stunt microscopic rust.

I guess the next stage is primer, right? Any old primer? I believe epoxy primer is best as it's non porous but not really sandable or great for visible body work.

So let's brake it down into two parts - underside/wheel wells (highly exposed) and upper body work.

when I have cleaned up some bare metal what do you recommend I put on these areas? So that they can be left for up to a month before getting paint?

Thanks a lot.

EDIT: Does anybody have experience with Bilt Hamer Epoxy Master? I have heard great things about it, and BH in general. I might buy some of that to apply to the underside areas that I clean to bare metal, or general areas not visual exposed to the eye.
