The RB is a great platform, and unless you are pushing 750+whp you can make them reliable, and even then, if you build them right they can be beasts pushing big numbers. The biggest issues are the oiling problems, and cooling, both of which can be solved fairly easily. The ring lands on the RB25 S1/S2 like to crap out beyond 450hp, but you are planning on taking care of that.

1JZ/2JZ are about the same cost wise as an RB swap (trust me, I have looked into this in MAJOR detail). Parts availability for the RB in the states has increased 10 fold in the past 10 years, and it isn't difficult to find mostly everything these days.

Since you already have the RB25, it will be cheaper to build it like you said than start from scratch.

There's one of these guys in every Nissan forum - Just put a 1J/2J in it brah, never mind it's a Nissan, Toyota rulez!

Keep it Nissan!

FYI, the 1J/2J are both great engines, no hate on them, and I respect people's decision to swap them, but I think the point of this thread was 'help me build my RB25det' not 'help me decide to swap another engine into a vehicle I already have a great engine in' - right?
