'lo ppl,

I'm rebuilding a '91 NX, and want to increase the factory 9.5 c/r to 10.5, or maybe even 11.0 (kill all those honda freaks! :) )

I read that I can use 300ZX Non-turbo pistons to achieve these results... Any comment or problems for this swap?? Anyone else increased c/r using this method or some other way?

I'm not planning to go Turbo, I want to keep everything "normal".


thanks

Its an easy swap, you just have to narrow the small end of the rod 0.020" as the pin boss of the vg pistons are narrower.
