Only the R34s

ok next question....is the vvt that big of an improvement????...ive read about it and it sounds good. but when your shopping for an engine its cheaper for r33 and r32..obvisously...so i was wondering if it would be a noticalbe difference or not...

I would not spend more money on a R34 engine, but that is me. You need a different ecu.
