Renault 5 Turbo.. same engine???

[CBA]

Looking through my haybes volvo and reno 5 manuals, I noticed the carb - weber32, and the engine are pretty much exactly the same...

Now I dont want to turbo the engine, not got the money or the will - but I wonder... follow this.

The volvo 340 is "detuned" at the factory for longevity, thats why its engine doesn't produce as much power (but goes many miles further) as the 99% similar reno engine...
Now could I get a reno 5 weber 32 (tuned for power, or more so than the volvo) bolt it on and hey presto extra power?, maybe the cams and pistons+rods from a reno 1.4 can be chucked in too??? - have to go over the manual again but it looks promising so far.

the baseblock is identical and that's about it.

the Weber 32 of the alpine turbo can't be used on a b14 simply because it is designed with all the jets for loadpressure; even with the carb placed between airfilter and turbocharger!

the Weber 32 DRT on the na C2J can be used.. but; this engine has a slightly different cam, other pistons, other cylinder heads, other manifolds and so on.. and what does it put out? 70hp, exactly the same as what you start with

for the solex's on both NA and turbo models it's a simple story; either use all the parts to accomodate with the turbocharger (take a look at my B14Turbo topic for an example); or use the na solex version with solex (and all accomodating parts..) to get a B14.3E idea; but that's a powerloss instead of gain

Indeed, even Group-B Renault Maxi turbo rally car had same baseblock, imo, head being much different as pretty much else, also had carb before turbo, petrol mixed in, compressed by turbo and entered after that to intake and to engine. Only french feel ok with that I mean, I have bit of problem mixing almost explosive mixture and running it in tubes at engine bay in quite high pressure, I mean with petrol alone it is not so bad, but mix it with proper amount of air and it says kaboom from smallest spart, but sink spark plug into petrol can and hit thse spark, in most cases it does not ignite, not enough oxygen, however I don't recommend to test, sometimes petrol can have just over critical point of oxygen in it and then it ignites, even not likely there is that possibility

Anyway some NA tuned Alpine head with twin carbs might be something special in it, proper old school machine

R5 Alpine turbo (or gordini as they call them in uk) had that very same system, the baseblock of those rallycars was bored out and larger bushes were fitted to give it a 1.6l capacity; those things made about 350bhp i believe? engine was placed behind the driver indoors, that is quite cool actually, you'll never rain wet when you're working on the engine

this carb before turbocharger and the fact that it had no intercooler were the reason the std alpine/gordini turbo made slight less power than the GTT model, however the head is much; much better designed and has bigger valves!

Renault 5 Alpine Turbo was nowhere near R5 Maxi Turbo.
First of all, Maxi Turbo had Bosch K-Jetronic injection system unlike Alpine's draw thru system.
And those engine was never the same. R5 Maxi Turbo, had ball bearings at camshaft and crankshaft for less friction. The displacement was 1.5+ with a 77 mm bore and 82 mm stroke.

BTW, if any of you want a Cleon stroker (1557 cc) with a 77 mm bore and 83.+ mm stroker send me a message.
It is cast, and handles around 1.3 bar with proper tuning.
On a N/A C1J engine with RC 9:1 and twin barrel carb it devellops around 75 hp and 125 nM of torque.
Cheers.
