is a atock b16a2 compression too high to run turbo???

no...as long as it is tuned proerly

aight dude thanx.. cuz someone told me it was too high to run turbo and i want to do a b16 turbo set up.. by the way anyone know a good set up for a b16 turbo.. and any numbers on it...Time....

I think that its not too high. but ideally its too high, and more hp numbers could be realized if you lowered the compression.

a head gasket to bring the compression from 10.2-1 to a 9 will be perfect.

You are nuts dude... have you any idea how thick a head gasket would have to be to drop compression a full point? You would NEVER want to run something like that with a turbo either. Bad advice. :nono:

Actually, higher compression will give you more hp, but a smaller tuning window.

That is true but a lower compression motor will take much more boost and eventually out power the higher compression motor that is boost/tuning limited. A high compression motor is ideal for low boost and a good engine management system tuned properly.

The headgasket idea is the worst way to lower compression. Not only does it reintroduce detonation that you are trying to avoid with lower compression by lessening the effectiveness of the quench zones, but it also is easier to blow out because of the larger surface area that detonation can destroy.

Well ultimately, the higher the c/r the higher the hp, period.

Thats why drag hondas can sometimes run 13.5:1 c/r with 20psi boost.

It all depends on the kind of gas your limited to, as well as great tuning :)
