Im building a d16z6 in my 91 CRX DX...I was reading a thread about pistons being swapped out with other pistons to increase Compression...Now the question is...can d16A1 pistons from a usdm 1g integra increase the compression significantlly on the z6 without the compression ratio being super duper (yeah i said it) High... If thats the case...A 3 layer head gasket can be used to lower it aswell...I was reading the thread but it really didnt give me answers...

 

Check in the FAQ for compression calculator. You can mix and match different engine components and figure what compression you will be at with a certain combination.
