Hi all, firstly dont want this to become a bitchy battle!!
My car is r32 4door (rb20) with following mods, apexi FMIC, Apexi Power FC, HKS oil cooler and relocation kit, full turbo back exhaust, cold air induction and pod, r33 turbo (s2), full HKS suspesion, clutch, diff, front and back struts, floor brace etc etc, you have the idea. Its a great car and planning to keep for next 10 years, yes 10 years! but car is already tied from hard life in japan and now from me on track. It is also my daily drive
I have done heaps of research over the last year and know the pros and cons of both just want experience to make the best call for the long term plan. Due to funds doubt I will have enough to get a turbo so rb25 will have to do for now. but want car to run reliable 250rwkw (with a new turbo im guessing)
1. rb30 bottom with rb25 head.
2. rebuild rb20 to rb24 and do some extensive head work including rb25 valves if they fit.
Both will have forged bottom ends. and want to use my power fc (r32)
I guess it comes down to this, if you were spending this sort of money with a 10 year out look will one end up being more reliable, cheaper, enjoyable than the other.
cheers
