I have Acura Integra LS 9.2:1 forged wiseco pistons in my stock sleeved GSR block. I also have the stock GSR head and stock head gasket.

The question is what is my compression?

Is it 9.2:1 or does my stock GSR head raise the compression to 9.5:1?

Thanks

I calculated 9.555 with the info you provided me, if the deck or head have been milled could be slighlty different. HTH Also you will not truely know your compression ratio w/o cc'ing it, we have done a couple of motors and cc'ed them and they were quite a bit off what the manufacturer stated.

MY block was decked .001.

What is the Bore and Stroke of a B18A/B (LS) in mm?

What is the Piston Displacement cc per piston for LS?

And what cc per cylinder is the LS pistons?

Thanks again for the help guys.

I am N/A right now and for some reason my GSR feels really slow...slower
than 9.55:1 compression...


Thanks Boostfed btw

Stroke is 87.2mm, everything is teher, you don't have to make any calculations, is is prefilled with bore and stroke and bore size for each prospective piston. Easy easy.
