Re:compression?

yeah for sure man, if its a D16A6 like mine then it has a 9.1:1 compression ratio, but i'd still get a thicker head gasket, thats what i'm doing, they are cheep.

Its a very good engine to turbo, cuz its cheep if youscrew someting up.
but i dont think you need rods and pistons, unless you want to run over 10psi on it.

Re:compression?

I wouldnt even worry about replacing the head gasket either. The D16/D15's have very turbo friendly comrpession. The only advantage switching to a new headgasket would be to run a metal (triple layer gasket) like the d16z6 gasket. The a6 has a composite gasket.

Re:compression?

Well, there is a sligh difference between using a block that was deigned for VTec, and a putting a VTec head ona non-VTec designed block.. you start raising compression. The swaps are called "mini-me". I think we're still debating about this boosting a mini-me or not, I have a mini-me, and the compression is pretty high. Not good for boost, but I'm waiting for a few of the elder turbo gus gets to my post on boosting a mini-me. Seems they've done it with success. Oh well..
