So I have an 91 crx dx that im building the motor in , this engine is going to be a buget high compression built engine
so I know if I use the 86-87 integra pistons that the block will have to be bored .04 over to fit the pistons but my question is will the valves hit the pistions???
Also will the 88-89 interga fit or will they hit the valves, i know the 88-89 pistons a better for raising compression but I dont want to waste money on parts that won't fit
the last question I have is what compression numbers am I looking at if I use either one of these pistions??

these will be going in the stock engine, I plan on using eagle rods, honda bearings, stock crank, ARP bolts for the bottom end

Thanks for the help, any segustions on parts to use/ good companys to get stuff from is welcome

 

I never heard of a 86-87 Integra...

You can always measure piston height from pin to highest point and compare it to your stock pistons and go from there. Also, it's been done before, matting eagle rods with cast pistons, I just hope you know what you're doing.
