Im possibly thinking of buying my mates engine for my Escort Cosworth, It is very big spec

ported and polished 4x4 head, bd14 and bd10, double valve springs etc.. 200 block with 10 long studs, standard size forged pistons with valve cut outs.

The compression ratio is standard tho, 8:6:1. Will i be able to run my Gt30 turbo? Gt3076.82. Im wanting around the 500 Bhp mark, will this be acheiavle and will i be able to run the boost to get this.. around 30 - 34 psi??

Any advice would be great! Thanks

I would have gone for around stock comp on a GT30 but if you monitor EGT and power output when mapping to be sure your not loosing power with boost it should be ok.

mark what power level is standard comp good for your in your eyes witu corect mods and mapping?

I run the 500hp engines at 8-1 and the 700 to 800hp engines at 8.5-1,
Mapping and engine spec has a lot to do with it.
