As the previous one departs, the next one arrives (literally the same day :)

Sub here for more 21 Turbo shenanigans!

Bye bye

I've kicked the R9 out of the garage to start laying out the puzzle, started tidying some stuff in the engine bay, cable routing etc. Nothing too exciting, so here are some pics of the incredibly clean shell.

I cleaned off some sticky goop stuff, I assume an underseal of sorts from the subframe, think I might gravitex it. I think I saw new subframe bushes in the parts boxes as well so may just be easier to drop it, coat it and lob the bushes in at the same time.

x20220522_141626_RS.jpg


The engine needed the crank seal fitting and a spigot bearing so they went in

x20220522_174309_RS.jpg


At this point I was considering chucking the gearbox in, I didnt in the end as I wanna coat the subframe but I dressed it with legs and some fittings

x20220522_174502_RS.jpg


I put the flywheel on the engine also, however that got cut short of fitting the clutch as the one that came in the boot supplied to the last owner as a Turbo clutch....isnt :( I knew as soon as I looked at it, but hey ho, I guess now I need to find one lol

x20220522_163707_RS.jpg


My garage floor now looks like an autojumble!

Yep - my 1986 Phase 1, as thread-ed here... https://cliosport.net/threads/phase-1-renault-9-turbo.823533/

Currently sat outside the garage under 2 covers, I will have to kick it out of that spot shortly too because I need to do a wheel bearing change on my Clio V6 there lol
very good car, my father ran a Renault dealership for many years and i remember him having a red R9 Turbo as a demonstrator, i had a le car 2 5 turbo in white and a year later a red mk1 11 turbo (quad headlights) which is probably the car i had most fun in ever

after seeing your thread it stirred a memory of seeing the Renault 21 turbo radio controlled cars at mallory park in the 80s. i think they were there as a support to the GT Cup ? i wonder if any of those models still exist ?

Yes mate they're quite collectable now, the Yankee 1/4 scale models. I owned one myself for a while in the mid-2000's but sold it due to being a new dad/very skint...wish I could have kept it. I have a pic somewhere of it on the bonnet of my own real 21 Turbo. They're selling for 3 and 4 times the money now.

While I am prevented refitting the engine and box by the lack of a clutch I decided to drop the subframe and have a crack at making it less yuk.

Gave the vibration dampener a bath

x20220618_165849_RS.jpg


Then spent an eternity cleaning off the sticky underseal grot off, and the greasy and oily build ups

x20220618_170728_RS.jpg


x20220618_170731_RS.jpg



x20220618_175257_RS.jpg


x20220618_175152_RS.jpg


Razzed it over with a knotted wheel

x20220618_173810_RS.jpg


Then the good old Bilt Hamber Hydrate 80, Bonda Primer and Gravitex combo

x20220618_185901_RS.jpg


x20220619_124302_RS.jpg


x20220619_153740_RS.jpg


Much better. Ready to have the bushes pressed in when its dried properly.

Prepping the subframe for fitting, the nuts and washers I replaced but the bolts were OK so I cleaned and greased them, then fitted the subframe bushes. The old large washers under a 36mm socket are perfect for this.

x20220702_151530_RS.jpg


x20220702_154525_RS.jpg


x20220702_155826_RS.jpg


Then dropped the 'box on - it's easier to lift the subframe and box in together than get the box in afterwards.

x20220702_164527_RS.jpg


And in she goes.

x20220702_172943_RS.jpg


Then I turned to the clutch slave which looked a bit manky

x20220702_173001_RS.jpg


I punched the piston down, cleaned the bore up and popped the piston out with some air pressure

x20220702_173632_RS.jpg


Bit of elbow grease and it's looking a lot better. Note the holes in the back of the piston that feed fluid in to the U-profile seal to expand it into the wall of the cylinder

x20220702_175526_RS.jpg


x20220702_175537_RS.jpg


New seal fitted, piston & spring back in and then a new dust seal.

x20220702_180204_RS.jpg

Popped the slave on the bellhousing along with a new fork and a new bleed pipe and new release bearing

x20220702_181256_RS.jpg


x20220702_185223_RS.jpg


Then, in anticipation of refitting the engine on Sunday I put the steering hydraulic lines back in, and unfortunately as I tightened the back union the threaded segment broke out of the rack! FUMING!

x20220702_192801_RS.jpg


Stomped off in a strop.
 

DaveL485

ClioSport Club Member

Came back to it Sunday and had decided I wanted the engine back in come hell or high water so I had to swap out the rack for the rebuilt one from my white quadra, I can source and rebuild another for that one I guess! Pipes went back in OK this time.

x20220703_142735_RS.jpg



x20220703_142739_RS.jpg


Annoyed at the waste of time and money. Anyway. Reconnected the speedo cable while the engine wasnt in the way. Old skool mechanical cable, none of this electronic bumfluffery!

x20220703_132210_RS.jpg


Got the engine ready to go in, brand new engine mounts to go with the new gearbox mounts and subframe bushes, new clutch, new spigot bearing, the whole 9 yards :)

x20220703_145423_RS.jpg


x20220703_145444_RS.jpg



x20220703_145900_RS.jpg


x20220703_160502_RS.jpg


Realised as I strung the engine up that i'd not attached the gearbox earth so popped that on

x20220703_161639_RS.jpg


Then (i've learned this the hard way) I checked the locating dowels were all there and that I didnt have dowels in both holes on the engine/box. One was missing in the end so I dug a new one out of the cupboard still in its Renault bag :)


x20220703_162027_RS.jpg


And then...

Garage is like a sweat box at the moment! I lost nearly two kilos on Saturday lol - still, cracked on! Got all the bellhousing bolts in, I couldnt find the ones with the car so I had to raid my stash of spares.

Water pump back housing threads cleaned and fitted

x20220730_150217_RS.jpg


Turbo support fitted

x20220730_162746_RS.jpg


Starter motor fitted, i cleaned and painted the rear bracket but i'm missing the L brackets to the block, might have to make some... then the alternator top bracket.

x20220730_162801_RS.jpg


x20220730_162756_RS.jpg


Then I dragged the engine loom out and set about repairing ropey connectors, and re-taping the loom

x20220730_165751_RS.jpg
x20220730_170752_RS.jpg

New plug needed here

x20220730_173130_RS.jpg
x20220730_180556_RS.jpg


x20220730_180601_RS.jpg


Cleaning and sorting this took so much time, but its done properly so I lobbed it back in the car and then started sorting through boxes.
 

DaveL485

ClioSport Club Member
  21T, 9T, Meglio, V6
Refitted some easy trim and stuff while I was sorting, this is the primary intercooler bracket/surround (the 21 has two intercoolers from the factory)

x20220730_192918_RS.jpg
x20220730_201034_RS.jpg


Clutch line located and connected to the slave

x20220730_201010_RS.jpg


Oil cooler/Aux coolant pump bracked refitted too

x20220730_201029_RS.jpg


And then the engine loom mostly routed and plugged in with the ECU and primary relays

x20220730_201202_RS.jpg


Crawled underneath and hooked up the gear linkages and reverse defender - short of clutch fluid & bleeding this should be a working gearbox now.

x20220731_144135_RS.jpg


Carried on refitting bits and bobs, working on these things so long gives the advantage of knowing stuff like this particular little woggle clips on one of the fins on the gearbox bellhousing and holds the TDC sensor wire between the sensor and loom.

HT leads cleaned and attached

x20220731_160754_RS.jpg


New fuel lines fitted from the hard pipes to the reg/rail

x20220731_160800_RS.jpg


And there's that little woggle for the TDC sensor wire :)

x20220731_161146_RS.jpg


Cleaned, painted and fitted the power steering pump rear support, this is also an earth point and the bottom bolt holds the oil level sensor bracket too, which was also all fitted.

x20220731_173140_RS.jpg
x20220731_173147_RS.jpg


Inlet manifold support cleaned, painted and fitted

x20220731_181347_RS.jpg

After so long sat doing nothing it seemed surprised to be back in use!

I gave the alternator a clean up and dusted a waft of silver paint on the front

x20220731_181358_RS.jpg


Then I got the remote oil cooler pipes and freed up the collars, making sure they were well oiled. These are a sod for seizing to the pipes and then you have to wreck the pipe to get it off. Three were fairly loose anyway, one was solid so I heated it up and got it free, then i span all the ends with WD and an air gun until they were nice and free. Note - if you heat these remove the tiny green union seal from the end first or you'll cook it, it wont seal and it'll piss oil out.

x20220731_184126_RS.jpg


Oil cooler located, cleaned and blown out with an air line, then plumbed in with the oil pipes. This should complete the oil pressure circuit.

x20220731_185346_RS.jpg


Post shenanigans there is a pleasing number of empty boxes

x20220731_185355_RS.jpg


I guess next tasks are alternator, power steering pump, then check the fuel system, get some oils in the engine and box and see if she will crank over. I wont fit any more ancilliaries like water pipes and boost circuit until I can show it runs.

Continued assembly of the engine bay, alternator and power steering pump on

x20220813_181211_RS.jpg


Hoofed some oil in it as well, primed the fuel system with some fresh fuel and... (this was genuinely the first turn of the key too)



Gave the shafts a clean up to finish

Ive had a few stuck injectors giving a misfirey first start on the last couple of first startups after rebuild/long layup. Had to fire carb cleaner through some c20let injectors to get them going while giving the injector 12v to trigger recently, pikey injector clean

One has been busy of late, including a blast across France and Germany for laughs. Saw a raft of 21 Turbo at a French show, been so long since I saw them in these numbers. It felt GOOD :D This white Ph2 made me pine for mine a bit, I have to admit.

20221001_114412.jpg


Aaaaaanyway. I have also continued the tinkering with the subject of this thread.

Front hubs powdercoated and assembled with new bearings

20220829_150417.jpg


20220829_152905.jpg


20220829_154248.jpg


Shaft in and pinned, new wishbone and stub axle fitted.

20220829_170119.jpg


Cleaned and painted the wishbone air deflectors, these direct air from the bumper vents through the channel to the front brakes.

20220910_163949.jpg


And fitted

20220910_180702.jpg


Started assembling the cooling system

20220910_175708.jpg


Cleaned and refitted the VIN tags

20220910_191326.jpg
 

DaveL485

More cleaning and painting

20220829_150424.jpg


20220910_191345.jpg



20220916_181148.jpg


Got the cooling system together (HOLY s**t jubilee clips have got expensive!)

20221009_155349.jpg


Shiny new


20221009_155358.jpg


20221009_155405.jpg


Mikalor's for the boost pipes

20221009_155355.jpg


And then I ran it up for 20mins, up to fan temp. Let it run with a fan on for a bit, heater seems to work OK, no issues to report really save the header tank cap was leaking so I stuck a Megane one on it :) Ready for the head bolt retorque now!

20221009_173113.jpg


Can't find a bloody fan switch, or the top crossmember which is annoying... need to source some parts!
 

DaveL485

ClioSport Club Member
  21T, 9T, Meglio, V6
OK then time to retorque the head bolts and set the valve clearances.

x20221022_160149_RS.jpg


I found a temporary crossmember in roof storage so stuck that on and fitted the new rubber woggle things for the intercooler

x20221022_161928_RS.jpg


x20221022_161958_RS.jpg



x20221022_162011_RS.jpg


Once that was done I ran it for a few mins, topped up the coolant and then pondered the next task. I decided to clean up the fluid leak underneath on the rear beam. This escalated...quickly.

x20221022_173259_RS.jpg


I then removed the mongified fuel tank straps, common issue on these. I'll make some new ones, I did this for my Quadra already in stainless.


x20221022_181303_RS.jpg



x20221022_181305_RS.jpg


Mmmmm CRISPY

x20221022_181308_RS.jpg


I have a new exhaust heatshield in decent nick to go on it so this one is headed for the bin.

Then I attacked the back axle, now the brake disc torx screws have always been a pain but with decent impact guns they usually razz out ok. Not this one though. The ugga dugga ripped the torx splines out - feck. Then I reverted to my backup, the old hammer and chisel method. That gets the bad ones out 99% of the time. But not this time.

x20221022_183402_RS.jpg


In the end I had to drill the top off, stupid thing. Then carried on disassembling.

x20221022_185116_RS.jpg

I wanted to just take the beam to be blasted, so I needed the ABS sensors out, as per usual this didnt go well for the sensors. What a waste, as these were testing OK.

I dug the powdercoated caliper hangers out of the spares box, chucked the used ones in the spares bin just in case.

x20221023_161344_RS.jpg
x20221023_161346_RS.jpg


Then I decided to have a look at the calipers themselves, having bought a rebuild kit with new piston recently to see if it would fit. Some interesting workings around the handbrake mechanism.

x20221023_165346_RS.jpg
x20221023_165353_RS.jpg


x20221023_165358_RS.jpg
x20221023_171737_RS.jpg


Inside the back of the piston

x20221023_175858_RS.jpg
x20221023_175924_RS.jpg


Of course, both calipers have broken bleed nipples so they need to be drilled and tapped out, I did one to M7x1.0 but i'm not happy with it, I have some M10x1.0 repair nipples to go back in so this is the first thing to do before I fit a rebuild kit in there. Didnt have the right tap though so ordered that.

Got the axle blasted so all the shananigans revolve around that this update.

x20221105_140301_RS.jpg


Treated

x20221105_143326_RS.jpg


x20221105_143331_RS.jpg


While this dried off I cleaned some other bits up, and attacked the calipers

x20221105_161330_RS.jpg


I also stuck the calipers in my little sand blast cabinet, before prepping for tapping by drilling the hole out to 9mm

x20221105_163202_RS.jpg


First tap

x20221105_163425_RS.jpg


2nd and 3rd taps

x20221105_163815_RS.jpg


And its in

x20221105_163916_RS.jpg


On to the second one

x20221105_172112_RS.jpg


Same again

x20221105_174002_RS.jpg
 

DaveL485

ClioSport Club Member
  21T, 9T, Meglio, V6
Threw some paint around

x20221105_175644_RS.jpg




x20221105_185618_RS.jpg


All the innards cleaned up

x20221105_185625_RS.jpg


Paused this, went over the axle with bonda primer. Each coat takes AGES, its fiddly to paint.

x20221105_185640_RS.jpg


x20221105_185645_RS.jpg


Back to the calipers

x20221106_143040_RS.jpg


Threadlocked the bleed insert into place

x20221106_150835_RS.jpg


Pleased with these, new pistons and seals fitted, good to go back on now.

x20221106_151427_RS.jpg


Then the axle got come hard wearing black, this is after the second coat

x20221106_135222_RS.jpg


In the midst of all this I removed the handbrake cables, took the mechanism out for clean-up, removed a shock bolt with a spinning captive, and started making the new fuel tank straps.

x20221106_161447_RS.jpg

Saturday morning I spend working on another 21 Turbo, but after it got dark I headed in the garage and got cracking. I kinda feel like i'm further into this than I wanted to be, but isn't that always the way?

Note to self/everyone, these are 14mm hex, M10 heatproof nuts, makes refitting the turbo on the manifold loads easier. Normal M10's are 17mm hex.

x20221119_132153_RS.jpg


First off I got that blasted seized torx screw tail out of the wheel bearing assembly.


x20221119_174748_RS.jpg
x20221119_175027_RS.jpg


Then cleaned up some of the paraphenalea for the rear axle

x20221119_182535_RS.jpg


I noticed one of the caliper sliders was broken... far right, top corner, the ear is missing. This means it could fall out, which wouldnt be good.

x20221119_182541_RS.jpg


Long story short, I employed a welder, bench grinder and a die grinder to get here

x20221119_184410_RS.jpg


That done, before the axle goes on the fuel tank needs to be held on properly so I broke out the plasma cutter and cut some strips out 30mm wide. The car came with some ally strips in the right width but they're way too short. I used those as a straight edge for the plasma torch.

I cut 2 x 30mm strips then a thinner strip which I cut up and welded to the straps where the bottom of the tank sits. This will stop the middle of the tank sagging when its full of fuel.

x20221119_203705_RS.jpg


I got to here and it was 8:30 and freezing so I knocked it on the head.

Sunday, again, I spent an hour on the other car bleeding brakes and so on, then carried on with the tank straps. This time, the drivers side ends. Doubled it over, plug welded it then angled the top.

x20221120_161832_RS.jpg
x20221120_163051_RS.jpg


Did the same for both. You can see here how much stiffer the T-bit makes it along the bottom of the tank.

x20221120_163119_RS.jpg


Fitted them up to make sure we were good before painting and fitting of the rubber shroud


x20221120_163841_RS.jpg


Then some primer, 2 coats yesterday, then some black to go on this week.

While the straps were drying I started assembling the axle on the bench. Wheel bearings on...

x20221120_171631_RS.jpg


Tapped out the torx scew holes for the brake disc retainers, look at all the grot! Taps are great for cleaning out threads.

x20221120_173044_RS.jpg
x20221120_173319_RS.jpg


Caliper hangers and calipers.

x20221120_183715_RS.jpg


The infeed brake line goes to a funny T-Peice on the 21 beam, this was rotten so I replaced it with a standard issue one. I tapped a hole in the axle and bolted it on (in the end I sat it a little lower than this)

Braided brake flexis and then the solid brake lines

Looking much better!

Finally I fitted the brand new ABS sensors, making sure the holes were clean and greased, hopefully these ones wont seize in!

That makes the axle ready to go back on the car, and then just the handbrake cables and mechanism left to hook up.

Brake pipe connected and handbrake cabled also fitted up with the refurbed pivot. Then I cleaned up the front anti-roll bar and treated it.

Thats your lot this weekend, as I also changed out the back end of a MK4 clio I bought for her indoors, & started messing with my lastest basket case/auction buy... don't ask me why. I dont know. I dont even have a CBT.
