Compression Ratio

[corollaman]

What compression ratio you reccomend to make to my engine with 2876 turbo. So not to be very sleepy in low rpm...? Do you recommend me to increase compression? I was thinking to put a trd head gasket so to increase my compression. Whats the highest compression you recommend?

cheers

well it kind of depends what boost you want to run in terms of reliability im sure a higher compression engine wont blow to bits running say 8-10PSI on that turbo... But if your planing on running high boost like 1.5-1.8bar definietly keep it low...

Speak to dantheman, thats IF he will give away his mystery build Hes running a 2871 not 76 but same thing different rear end.

around 9.5:1,
best way is with pistons and gasket
need a good tune or it could be bad

I would say slightly lower then standard if your gonna run that much boost.
