Wonderful, wonderful, wonderful!!!! :friends.gif::drinks.gif:

Your dalliance with a short back and sides from Stuttgart is now well and truly forgiven :grin.gif:

Looking forward to seeing where this one goes!! 🍿
 
You better look after her mate!! Sarah will kill you if you don’t lol.
I too am exited for what is planned for this lovely little Renault. Both 8’s ready for RRG hopefully

I think RRG will be the target to have it up and running then :D
 
The port spacings are different on the non 1300/1400 motors, therefore none of the early stuff is worth using. The early motors are Sierras, and the post 68 1300 are Cleons. They have different blocks and there's no comparison between them for mechanical strength either. Confusion sets in because the external sizes are the same, but there is about 15 kg more iron in a Cleon and in all the right places.
 
Interesting.

I was just spending Adey’s money for him after his comment on cheap engines not being available anymore.

I’ve a stripped down engine which I’ll probably never get round to rebuilding, needs new liners and pistons, heads probably toast as it was skimmed to its limit before I cooked it again due to a burst rad. It has a piper cam in it but not 286.

I was going to see if @Adey wanted it foc but after looking at cost of liners, pistons and gasket sets it wouldn’t work out any cheaper than a built engine anyway. Thought it would give him the stronger bottom end with a slightly more aggressive cam and use the head he has. The turbo head might go again but I never checked.
 
@Steve Swan that looks lovely! Ive got not aversions to running a snorty motor in this one. Was already looking at webbers and manifolds even for the 1.1 engine.

Turbos are great but I think it would add way too much stress and complexity, I want to just drive this for (slowish) fun, rather than be chasing big numbers (the clio can do that bit for me) Runs out to the local pubs and hotspots is the main plan for it (plus looking super cool)

@Norwich Nick really appreciate that, such a nice gesture (y)
 
You can steal an engine from R9,10,11,12, 18,Fuego and Volvo 340. MK1 R 5 has the block ears missing for fitting in an 8, but you could invent something. Get a picture of the bottom spine of the gearbox under where the axles come out. That will give an indication of how Chocolate the box is, plus whether it has a real or stone age clutch, as it's a later car you might have the right bits.
Hi All,
Looking at the motor picture, its without an oil filter present , hence I am sure that the matching original R8 330 Box will be the weaker version with a flatter lower "spine" and unguided release bearing bellhousing, the diff planet gears and the sunwheels gear tooth design are also inferior to its later big brother which has the guided release bearing. There is however a conversion kit available to upgrade the early bellhousing to the later guided design[ Mecaparts] this helps with the Clutch operation when a 1397cc /1289cc motor is fitted.
I like the banded original wheels.
Cheers

The head will be fine, if its a gtt head, itll need more skimming off to up the compressor ratio anyway. If your conrods are OK, I can give my n/a pistons to Adey FOC. I've got alot of 2nd hand liners, in 'reasonable condition' again, he can have FOC. All he'd really need is a gasket kit, pistons rings and new shells?
 
Looks like you are all out of excuses then!!! You will need to find a Gordini turbo flywheel to mate the Gtt Motor to the 8 box that way you can keep the original starter set up.
I keep wondering where the Rapier wit of @DaveL485 is?? He must be saving himself.

Would it have to be a gordini, or would a standard mk1 5 one suffice?
 
There are several ways you can do this, depending on ease,cost or features.
You can make a GTT flywheel fit in the bellhousing, but the starter arrangements get irritating or you have to cut the starter bit out of the GTT box and weld into the R8 bellhousing.
If you go MK1 5 Turbo you get the smaller flywheel with the reluctor ring for the renix, so it is straight plug n play, plus it keeps the original type starter .
If money is no object TTV will make a hybrid flywheel which ticks all the boxes, you can have the reluctor ring of your choice, use the 180 clutch and original starter
It is whatever is easiest for you I suppose.

so is the difference between a turbo mk1 wheel and a non turbo one the reluctor ring pickup ?
 
Well it's Renault, so no, there's a little bit more to it.
All Cleon's That is post '68 1289 and 1397cc engines use basically the same flywheel with a 180mm clutch.
The 5 Gordini turbo uses the same style, but with the reluctor ring for the Renix.
There are however 2 effective thicknesses at 28mm for most and 23mm for the Gordini turbo, so getting the clutch actuation spot on is a bit of a Faff.
All later 80's on cars with Renix are 23mm. This was the Issue on @paule78 's car. It now sports a custom flywheel which is basically 5GTT and with 60-2 Reluctor, but with Mk1 5 Standoff and clutch pitching, which should get it over it's crappy feeling clutch, no doubt he will tell me when it's back on the road this year.
Therefor simplest and cheapest is to fit MK1 5 Gordini Turbo flywheel to the GTT motor and use a 180 clutch with a 5mm spacer fitted to the nose of the Release bearing to take up the missing space.
The 8 clutch mech has it's limitations, but works fine if everything is set up correct. It does not have the flexibility of everything that came after it.
The 8 is not the Dauphine, there's no comparison. The 8 chassis with the shell properly braced and the suspension dialled in will handle 200 bhp. Mine had getting on for 180 and I could use full throttle no problem in the wet. This is why the only Dauphine part in my car is the shell
It's hard to explain, but I had a Nice 5GTT when we did the original R10 turbo, which was just the roughest of the rough, it really was. As far as Driving went, the 10 would run rings around the 5, especially in the wet. It left you feeling that a turbo 10 was a thing Renault should actually have made.
 
Before we get too carried away I should really check it’s not all just scrap. It was oiled up before being boxed up, I’ve not looked at it in a while and the boxes have been shuffled about so will see what’s what. Might take me a little while as I’m not quite back to full grip.
 
I had a late 1397cc cleon MK1 5TS, not the early 1289cc with the warmer cam, that had the ring on the flywheel and renix.
I bought it sick and found out it had an 1108cc in it, got a 50 quid 1397 auto engine from the breakers and swapped flywheel onto it, and put a spigot bearing in as the auto didn't have one.
Boring story, but, long and short of it, late TS/TX flywheel might be a match?
