dimentionally the same.

But you wont be able to run a clio valver/williams ECU/loom setup, you will need to runa complete megane management setup.

Diff head, smaller ports, diff inlet manifold, coilpacks, diff TB, ISCV, injectors yadda yadda yadda.

buy a williams engine and have an easy life.

Oh and it doent rev any higher.

but whack a valver head or williams head on it, run the valver loom with a williams or a chiped valver ecu and you'll have a missile

for some reason all th hybrids i've driven have been faster than the williams i have also driven

nah i think il get the williams engine rebore to 84 mm
then get full head work done.
turbo etc etc like i said before.
anyone know were i can get upgrade gearbox ie strengthen or at least an lsd for a clio box.

also would a williams strut brace fit a mark1 ph1 clio 1.2?cheers

 

[Fred@BTM]

why the rebore?

 

[cliohybrid]

why the rebore?

its for a track day car only so want all the performance i can get

wouldnt bother with 84mm with a turbo, you'll have sealing issues.

You wont loose any performance by keeping it stock or clean up the bores to 82.5mm.

depends on the boost you are planning to run. If your thinking of sub 1bar gauge, a 2bar absolute of a 21T would suffice. Anything over 1bar gauge, and you'll be looking at 3bar absolute at circa £80 of the top of my head.

prob about 15psi max,probs about 1 bar?not to sure about conversion rate lol.

 

[Fred@BTM]

1bar = 14.72 psi (i think!)

 

[cliohybrid]

1bar = 14.72 psi (i think!)

thought it was rougly that lol.
i might just buy a rear ended williams and strip the whole front end down suspension engine and everything,

so you would be rebuilding a whole car, AND a trubo engine?!

I'd just be a straight car in the first place, and concentrate on the engine.
