Racing Blue MK1 Clio revival



It's been a few years since I've really played with this car so back story. Owned the Clio for about 3 years and in usual turbo Clio style it kept on breaking so threw a tantrum and bought a BMW M5.

Had a E39 M5 that was a boss did a fair few trackdays and nurburgring trips in that car, smashed the miles on it and wanted something different after 4 years of owning it.

After selling the M5 I got the Clio out for a year. Did 3 trackdays in it and actually got it to the level where it was pretty reliable. Until the engine spun a bearing on pretty much it's last trip before being taken off the road for winter.... 🤦🏼‍♂️

And at Anglesey

So threw another tantrum and bought a 2JZ swapped M3 with 630hp. This thing was ballistic on the straights useless in the bends even with ohlins r&t coilovers.

Sold that after 2 years and then decided I want to get my Clio back out. It's been over 3 years since I've seen it let alone driven it.
Ripped the engine out replaced the crank, made it all nice and made the fatal idea of having my inlet manifold vapour blasted. Didn't realised they used a media blast and then vapour blasted it. It was full of media that then dropped into the engine bores and wrote it off 🤬.

So with a trackday booked and no car. I called up my mate and asked if I could borrow his spare track car.....
 
The spare track car was a k20 swapped Mk1 Clio 😁.
51169829378_f1b8f766f5_o.jpg


It was flying around track all day and was faultless until I broke the clutch pedal but that was expected as it was a bit of a home brew affair.
I was hooked and so the path of building my own k20 Clio started 😁.

Bought a k20 with TDI ultimate cams, clockwise baffle sump, RBC inlet, 70mm throttle body, rdx injectors etc. So should make a decent amount of power!
PXL_20210512_140753147.jpg


I want to keep all the originals dials working so opened up the oil level and temp sensor and glued the thermocouple into a 1/8 not generic sensor that I drilled out.
PXL_20210525_063625022.jpg


PXL_20210525_082041487.jpg


The oil pressure sensor I tapped a thread for it into my sandwich plate and screwed it into that.

PXL_20210613_101152246.jpg


The water temp sensor I'm going to run a sensor into one of the coolant pipes.
So there's only one dial on the dash that won't work.... The speedometer.
I'm going to run an Arduino to run a needle that I'm going to retro fit onto the dash instead of the Speedo cable.
PXL_20210626_155145552.jpg


So I've programmed the board just need to wire it all up into some spare clocks and see if they work!
 
Didn't like the red fuel rail so took that off sanded it down and left it as bare aluminium.
PXL_20210707_113724170.jpg


PXL_20210707_150111340.jpg


And also bought a new coilpack cover for the engine.

PXL_20210722_085841826.jpg


Bought a ktuned side pulley kit to reduce the height of the engine as the top pulley can be high. Plus the subframe on the MK1s mean you can't run a p/s deletion kit as the alternator will clash with it.

PXL_20210803_111701312.jpg



So you may notice I bought the custom production engine mounts.... If your fitting this engine to a MK1 Clio don't get these mounts! The engine sits wayyyy too high to the point it's comedy level at how little the bonnet closes 😂 and how much the driveshafts will clash with the chassis rails.

So for the drivers side engine mount I've had to drop the engine 38mm. I did this by machining the chassis side 10mm and adding 24mm spacers on the engine side of the mount.
PXL_20210812_090810856.jpg


PXL_20210812_103914522.jpg


You will have to notch the subframe for the sump to clear. I know the steel sumps have more clearance but I didn't want to split open the engine as it already has a baffled sump inside of it.

PXL_20210812_102759387.jpg


Clearance is tight but all good once I've strengthened it back up with some steel.

Next up building the gearbox mount.

On the gearbox side the plate in the kit just doesn't match a MK1 chassis rail at all. Wrong shape, thickness, etc.
So I just got some 3mm steel and started welding up some pieces together.

PXL_20210812_122707912.jpg

PXL_20210812_124331265.jpg

PXL_20210812_131756420.jpg


With the mount made can see the diff on the k20 sits near enough the same place as on a jc5.
PXL_20210812_134813419.jpg


Started to add some strength back into the rail. Capped the ends up added a sheet of steel. Was about to triangulate some of it and then the welder ran out of gas!

PXL_20210812_154421878.jpg


Welds aren't the prettiest but it all has good penetration with lots of underseal burning while doing it.
 
Some of the goodies I've bought for the car are ktuned pro shifter
PXL_20210809_063532569.PORTRAIT.jpg


Kpro ECU
PXL_20210810_174623373.jpg


Big itg carbon filter. My mates k20 is an open cone filter and oh my days is it loud on the induction noise to the point it gave me a headache on the trackday! So definitely wanted something that was enclosed!
PXL_20210628_094116203.jpg


Mfactory racepac diff fitted with a longer 6th as it don't half rev high on the motorway with the small 15" wheels!
This was done by kinetic Motorsport.

Universal conversion adapter loom.
PXL_20210810_211710468.jpg


Brand new clutch with facelift flywheel as it's a tad lighter.
PXL_20210803_115545133.jpg
 
So done some strengthening to the chassis rail and subframe.

PXL_20210817_151643470.jpg


PXL_20210817_155035454.jpg


There's a triangle bar welded against the chassis rail on the other side too to spread the load down the rail between the notch too. Doesn't budge so guess it's working now.

PXL_20210817_145218977.jpg


Added a notch in the drivers chassis rail to ease aux belt changes.

With the engine back in

PXL_20210820_150919787.jpg


Started next with plonking the engine loom on.

PXL_20210821_112947276.jpg



Next up was feeding the brown and white plugs on the Renault loom back up inside by the glovebox as that's where the ECU is going to live. The ECU will tap into the brown and white plug for stuff such as starter wire, fuel pump wire etc etc.

PXL_20210821_145814585.jpg


PXL_20210821_154611200.jpg


Tapped it all back up and stuck the grommet back over it all.

Next made a mount for the power steering pump. Using the usual mercedes pump.
PXL_20210823_134236851.jpg


And lastly finished off the dog bone mount. Chopped the original bracket and rewelded it to suit the next height the engine sits at now.
PXL_20210822_095918691.jpg


Next up tomorrow is sorting the exhaust manifold out hopefully 😁
 
So today started with the exhaust manifold.
I'm using a standard 182 manifold like my mate had done. With the engine being sat so low it's in near enough the same position as the f4r sits which means I it's in theory a flange swap away from fitting.

PXL_20210824_092251327.jpg


Chopped the flange off which was hard work as I'm cutting right on the welds so it's about 6-7mm thick in places.
PXL_20210824_103832132.jpg


The k20 port spacing is very similar with the clio outer ports needing a bit of bending in to match. Did this with a few pie cuts and tack welded for now in.
PXL_20210824_133923439.jpg


And how it looks from the flange side
PXL_20210824_133813295.MP.jpg


Was trying to get all the ports flat ready to weld to the flange but forgot my ear defenders and tinnitus was slowly creeping in so called it a day.
 
Bit of a delay been to the Nurburgring and North Wales the last week.

So back on to the manifold
PXL_20210902_112522620.jpg


Mocked it up started welding around and forgot I don't have the 172 ARB fitted 🤦🏼‍♂️.
Fitted it, low and behold it hits the ARB 😂.

PXL_20210902_151138726.jpg


Did another cut further down the manifold on where it's 2 pipes and bent it up to clear the manifold.
PXL_20210909_133853066.jpg


Lovely now!
Also changed the plugs on the injectors to allow me to run rdx injectors.

PXL_20210909_122501529.jpg


PXL_20210909_122949706.jpg


PXL_20210909_123307807.jpg


Hopefully the rad turns up soon so I can crack on with that. Once that's complete I'll send the subframe off for powder coating.
 
Still no rad as it was lost in the post 🤦🏼‍♂️.

So been finishing off the manifold by welding a 3" flare and then 3" flange to suit my exhaust
PXL_20210917_105515718.jpg


PXL_20210917_112713988.jpg



Next up cut out a plate to plug the hole where the original shifter would live.

PXL_20210911_121720137.jpg


Welded it up and ground the welds back

PXL_20210911_132242041.jpg

PXL_20210917_095702919.jpg


Chucked a coat or two of black paint over it and bolted the shifter in so that's done.
PXL_20210917_120750392.jpg


Also trail fitted the intake

PXL_20210917_085705756.jpg


Next up probably mocking up the driveshafts for the length I need which I don't fancy as I'll get CV grease everywhere.

Same intake as me. Bargain they are.
Is yours the full big boy version? 90mm piping to throttle body and 120mm intake trumpet?
 
Started on the pedal box with the civic master cylinder.

PXL_20210920_100036280.jpg


It has a really annoying bolt spacing so had to bring one of the bolts in real close to it.

PXL_20210920_104619908.jpg


This is the angle it sits at, slight canter but enough to be fine.

PXL_20210920_104650467.jpg


The support brace is in the way of where the master cylinder is going to work off the pedal.
PXL_20210920_104632186.jpg

PXL_20210920_115657475.jpg


So chopped it and re-welded it back on. Also tack welded the nuts to make it easier to removing and refitting on my own.

Radiator turned up today too!
PXL_20210920_132708550.jpg


Chopped the front crash bar off as it's been so hacked up over the years for intercoolers etc that I'm going to make a new tubular one.

PXL_20210920_135317533.jpg


PXL_20210920_135746222.jpg


That's how's the oil cooler and rad are going to sit. I want to bring them together so I can have fogs again and have the front end looking stock.
Clearance for the water outlet on the block is decent.

PXL_20210920_140015426.jpg


Slave cylinder less that ideal. May tilt the rad slightly.
PXL_20210920_140009411.jpg


Going to order supplies and attack the car in the next few days.

Good progress. Funny how your rad clearance problems are reversed to mine. I really struggled to get a neat solution for the bottom hose as the thermostat housing outlet was so close to the fans/rad but clutch slave miles away. Must be how it sits in the Mk1.

You got the engine and box level and the angle of tilt sorted?

I think if I had to keep the rad in the stock position I'd be knackered with the outlet pipe 😬. With the front cross member chopped out its given me a lot more freedom but I don't want to go too far forward or ill be chopping the front bumper grill out which I don't want to do on the new bumper.

I've ordered a clutch pipe with a banjo fitting for the slave to hopefully save me some room.

Yeah I kept the angle of the tilt the same as the kit. Made sure the engine mount was sitting nice and level before starting the gearbox side.

Sweet all covered 👌🏻

Tubular and removable front is on my list once done.
My engine didn’t sit right with the engine mount on and gearbox mount bolted to the strut tower 🤦🏻‍♂️ Took loads of fiddling and faffing but glad I spent the hours doing so.

tubular front cross member makes engine removal so much easier. That’s what I have done, all be it I have a tubular subframe with no bar across the front so also have an engine cradle that allows me to wheel the engine in and out with front cross member removed.

Sounds good.
Any pics you can share?
 
Been a while since I've worked on this been flat out in work 🙄.

So started with capping off the ends of the front slam panel.

PXL_20210928_110235044.jpg


Bar will sit like so on each end.

PXL_20210928_110256189.jpg


Plugged up the ends of the bar with captive nuts so it bolts on and off.

PXL_20210928_155746841.jpg


Radiator on, in two minds if it needs all 4 mounting points 🤷🏽‍♂️.

PXL_20210929_104345657.jpg


Oil cooler on

I’m going to sell my exhaust manifold and down pipe if your interested or decide the 182 manifold don’t work

Thank you for the offer but I'm going to stick with the 182 manifold for now.

Managed to finally get the clutch pedal working.
Version 1 worked lovely. Bolted it up on the car and the steering shaft just went directly in its path so that failed.
PXL_20210930_103240878.jpg



Version 2 basically a m8 rod bent into shape to go around the shaft.



Just needs a small washer added on the pedal stop but shows I'm getting full travel in the cylinder.
Also a quick grind and paint to stop it rusting.

Added a small coolant overflow tank too.

PXL_20210930_135855677.jpg
 
Heat wrapped the manifold. Need to check the flange is flat before bolting it up tho.

PXL_20211007_133656140.jpg


Front crash, radiator support bar is now painted and fitted.

PXL_20211007_150625148.jpg


Pedal box fitted and just bent the hardlines around the master cylinder.

PXL_20211007_150638880.jpg


Wired up the bus bar for the battery cable, interior cable and engine loom to connect to.

PXL_20211008_130053231.jpg


And just bought this. As we all know MK1 clios were graced with such terrible sunroofs. Mine leaks badly so to fix that I'm swapping over roof skins 😂.

PXL_20211009_063021965.jpg
 
Finally got the gear shifter cables sorted.

Went with the racing circuits versions made to my length. The ends they use didn't really work with my setup. So there was huge play on the shifter.


So ended up turning down the bolts on the gearshifter to accept a M6 rose joint and also filing the gap just a fraction wider for them to fit into.





Also picked the subframe up from powder coaters and my 172 rack has turned up so can finally start building the front end up again now.
 
Started with building the subframe up.
New drivers rear bush fitted and 172 steering rack.

PXL_20211026_132244714.jpg


Still had to bend one of the pipes on the rack but less hassle than the valver rack plus less turns lock to lock is always a plus.

PXL_20211026_135232686.jpg


Fitted the new oil cooler.

PXL_20211026_135218475.jpg


Clutch line fitted and gear cables grommet fitted.

PXL_20211026_135628281.jpg


Slowly coming together. Will fit clutch reservoir tomorrow and start building the front suspension ready to measure shafts.
