What crown wheel and pinion will you run?

Our metro van had a similar spec'd engine, but with an MG metro Cam. Mate about 150 bhp with 14-15psi, running a T3. We broke the first motion roller bearing in the gear box, but otherwise it went well.

What compression ratio will you use?

If you need an intercooler then I have an RS intercooler or a Sierra 4x4 intercooler which will both be up for sale soon.

thanks, but i have all my parts already.

as for c/r, ive no idea!

ask me tomorrow for discount

you need to work that out or chances are you'll melt it all on your first outing....

if i did work it out, what help would this give me as far as my spec is concerned? thanks

Tell's you how much boost you can safely run, how much ignition advance etc etc
