RB25DET is a pretty straight forward swap as that engine is in some C35's...Jz is a power house but a 25 will be easier to do and it has sufficient power(stock).
yea u real hold up de-- op thread deh .. as (trinibuggy) posted it much easier, with the swap but honestly it will come down to what u want but...JZ power MAD, but with a good RB u could take him, if u want to be different then JZ IMO/ but RB25DET does give more than enough power if that's what u are looking for.
