Hi, i have a rb25 ready to replace my RB20.
Its running standard internals, with a match ported and polished head, Haltech computer, FMIC, 3 inch exhaust, etc,
i was going to go a big turbo and external gate but i cant be bothered now. A mate mentioned the HKS2540.
anyone know what power they are good for with the above setup on 1.3 or 1.4 bar, and when will it come on boost.
