@paule78, glad to see you’re stuck with the c1j, I think cars like this should carry as they are, being improved upon. Changing engines would take away the history of the car.
Well done for picking up the spammers and getting stuck in

I can't guarantee that I can get it all back in but it is fun figuring it all out ... well mostly.

Well aren't we just spoiled with TWO death traps in progress between you and @Adey View attachment 150227View attachment 150227

Hey the difference being these cars wear their rust where you can see it and fix it ... my 5GTT is really good at hiding it letting you think its okay

sorry, didn’t read what I wrote as I was being shouted at by a 4 year old who wanted ice cream! You figured out what autocorrect didn’t want me to say, figuring out how to put it back together should be easy after that!

So my van is now full of gearboxes ready for the trip up north ... went a bit mad and have ended up with 2 x Renault 8 gearboxes and 2 x Renault 5G gearboxes ... the lots will eventually end up being turned in to one good 5 speed.

Made the decision that as the 8 needs a rewire anyway and that my 5GTT is already good that the EFI set up I have will be going on this

Also invested in the shocks this week as progress with the bank card is easier than that with the tools at the moment.

Mmmmmmmmmmmmm shiny.

going to be an animal once done. C1j turbo, EFI and a strong 5 speed box. You thinking of getting a cage too?

I think I better at least consider it

 

[Adey]

youll need brakes too just to be safe




























i have somewhere to keep your old ones

A little time on my hands with this project as the engine and gearbox are now being assembled way up north in Scotland somewhere. My other cars also don't need my attention so I have been spending time looking at a ton of Renault 8 pics figuring build options and direction.

So many of these cars were raced ... circuit and rally .. and in fairness they were pretty successful. I had planned on a pretty stock look and feel but the more I progress the more I like the motorsport touches and so I think more will creep in to this build .. not to mention the little extra safety seats, roll cage etc offer so all pluses.

Found a new old stock momo boss for the car and I had an OMP steering wheel in the garage ... removed the ships rudder supplied by the factory and now have something a little more capable of steering the power we aim to put to it.

I'm all for you giving the old 8 an bit of va va voom @paule78

So update time ... though the tools in my garage have been gathering dust recently my bank account is in trauma and Steve Swan up in Scotland is working away to give me a great gearbox/engine combo.

So first up Steve ... well we met in a car park near the border and goods were exchanged ... updates have been coming in thick and fast, I understand about 1% of what Steve has cooking but knowing how he drives his own cars I am excited to go collect the 5 speed gearbox and 5GTT motor he has for me. The gearbox will be the ungodly union of a R5G 5 speed and my original R8 4 speed ... it promises to deliver reliability and drivability with the 5GTT motor power.




The plan to install my EFI set up on my PH1 5GTT has shifted to installing it on this car .. so a trigger wheel was needed ... with so much being spent already this was no time to get cheap to a TTV 60-2 flywheel was ordered and a Valeo Green clutch to figure that element.



While I have a pile of parts off the car I have started passing some on to the local powder coater to freshen as much up as possible ... mindset is patina sleeper on the outside but shiny on the inside.



Then as the sun was out today it was time to start adding some speed in terms of weight reduction and sticker application




Onward and upward! As long as my bank balance holds out we keep moving forward ... update from Image Wheels is that my order is within a few weeks of being delivered

so much win. complete opposite from my build lol. very much liking the gearbox upgrade though. keep the updates coming

Very tidy, not shy with the pennies either! Good man.

It may still be early days to make sweeping statements like this!!!!!!!!!!! Watch this space......
By the way @Adey did you notice what was behind the flywheel in the picture

This is @Steve Swan volunteering to give a full blow by blow build description on the gearbox and motor

I spy it hiding away there, more pics definitely needed as much more power than I have already and id be scared to drive mine

We definitely need some updates

To be fair the Gearbox part of the build is well enough covered in my old website which is hosted here on this forum. The biggest change is the Availability (or lack of) donor boxes and the price of the parts. It could be that I have reached the age where I remember the price of many things which has in most cases trebled in the last 25-30 years, this really puts me off , but I do understand that anyone coming into this passtime does so in the full understanding of current market forces/prices, it's just me that is getting old!
I have a question I would like to ask. The clutch is going to have some work to ensure correct operation , I mocked it all up the other night and the release bearing is not contacting until about 60% of the total travel has been used up, this is no good and needs rectifying. There are 3 areas that can be modified to achieve a better actuation.
1. Use a deeper flywheel (standard 5 atmo has a flat and slightly stood off flywheel) , the stood off type works best in an R8 , but as we are using a 5GTT flywheel from TTV so this avenue is closed off.
2. Machine the bellhousing front face , so the release bearing is closer to the pressure plate diaphragm, This is not going to work in this case as I need about 5mm and 3mm is the max that can be skimmed off the bellhousing, and yet again because it is a 5GTT not a 5 Atmo bringing the bellhousing depth down is not a good idea as we have a 5GTT flywheel and pressure plate inside an R10 bellhousing which is tight because it was not designed to have a 200mm clutch and the chapter ring on the larger diameter flywheel.
3. Do something to the release bearing or clutch fork. I am leaning towards making a spacer (5mm) which is rollpinned through the clutch return spring holes to the release bearing, and then bearing and spacer are rotated 90 degrees and the return spring fitted to holes in the spacer and the clutch fork (same as the bearing)
Does anyone have any other suggestions. I have a pathological dislike of chopping things up and always prefer to make adapters as this involves no other special parts so that if the clutch or bearing needs replacing in the future it is a simple job

Amen to that! Parts prices lately make me break out into a sweat, especially Clio V6 stuff!

Does anyone have any other suggestions.

Got any pics of the setup? I am not familiar. Generic solutions would be...
1)Change for a concentric bearing / hydraulic setup. Probably a bit excessive.
2)Modify the fork to boost the bearing forward.
3)Push the pivot point the fork sits on, forward a bit. They are usually a steel bolt in thing threaded into the ally casting, make it longer.

ive seen a few pics on french sites of modified forks to change the throw but i cant find a pic at the moment. if i find it ill post it up

The set up space is very small, so there is not a lot of room to play in. I made a concentric slave cyl for my Dauph using the good old Saab 99 piston there is no room in there at all. Plus my Dauph has a bias pedalbox fitted. It works ,but it is an extreme solution
The pivot is just a hollow cast into the bellhousing which is only about 3mm thick (ask me how I know sometime) so altering the pivot point is not easy
Modifying the fork is doable, but without having some kind of idea all I can see are unfavourable angle contacts on the face of the fork @Adey If you can get a picture or a link this would be a big help
I still fancy a 5mm spacer on the back of the bearing, so nothing is modified and can be replaced without further issues
