my friend told me the zc pistons from a junked crx i got from a friend (body only damage) would fit in my stock d16a6 91 crx si block and that it would raise my compression. have any of you honda "guru's" out there heard of this or know what kind of mods i would need to make this happen, or performance (compression/hp) this combo would achieve? thanks a lot.

stock (d16a6) head w/ stage 2 port + polish
adjustible cam gear
full bolt on 2.25"
pm6 ecu chip

 

yeah they will fit in...you can buy them new if you want to from http://acuraautomotiveparts.org then need to be from a 88-89 integra, they should yield at least a 11:1 compression...

 

yo john its brian.Ya i would just hone the walls and get new rings.That way everything seats properly!
