thick headgasket?
so i REALLY want to build the bottom end of my b16 so i can actually run a good amount of boost ( 8 psi now) like 12-14 psi, but i just dont have the damn money, so how reliable would it be if just threw on a thick *** head gasket to lower the c/r down to like 9.2:1 ? obviously it wouldnt be as good as building the bottom end, im just wondering if it would be worth it at all? worth it to me would be if it lasted as long with the thick head gasket on like 12+ psi, as it would last stock on 8 psi, do you think that would happen? im just worried that i will still shatter my ring lands, any comments are appreciated!

so a 9:1 c/r b16 on 12-14 psi will only make the same power as a 10:1 c/r b16 on 8 psi with the same turbo? i wouldnt think thats true.....maybe im wrong but i would think the first one i listed would make more power.

I remeber seeing a dyno for a ls teg with i think an sc61 and only a cosmetic head gasket (almost stock motor) tuned by neptune hitting around 290whp with like 18psi...
However lowering compression just makes it a little safer to run more boost but more boost with lower compression dosen't always mean more power...It will mainly depend on who and how well the car gets tuned, I think i'd rather invest the money somewhere else personally

Re: thick headgasket?
as long as you keep away from detonation, the thick head gasket will definately allow you to run more boost. however, with more boost comes the possible chance of detonation, and since the gasket is thicker, more of it is exposed. its kind of a double edged sword. damn b series
