what compression ?

if it was yours then 40psi held.............

.....but if it was mine i would ask who-ever is mapping it for their advice

7.?-1 if memory is right, what ever the low comp pistons are from cosworth.

and it hasn't got a urbo yet. one i find out how much boost the engine would take i can then decide on a turbo

radiant red

psi is dependant on turbo entirely.... decide what power you want, and where you want it in the rev range then spec your turbo to suit. A GT30 sounds like the sort of thing you are after
