Hi tuners,

I own an r32 gtst skyline........swapped for a rb25, tuned yesterday

Other mods performed whilst doing the conversion are as follows:

all parts new except the afm

garrett 3071r

apexi power fc

600cc injectors

osgiken twin plate

greddy profecb spec II

z32 afm

While it had the rb20 in it i had already done the usual bolt ons, 3" turbo back mandrel exhaust, kn airfilter in stock box, trust intercooler 600x300, walbro hp fuel pump. Never did a dyno run with old engine and gear. All aftermarket gear mentioned here stayed in the car.......exhaust slightly modified.

here is what power i made, remembering 40 degree heat and wheel spin. Oh yeah 17psi and 98 octane

First pic is power and boost, second is power and a/r

Power FC ECU with Nissan S15 440cc injectors and Z32 AFM

Front Mount Cooler, 3" turbo back exhaust, Bosch 040 intank.

Previous turbo was a KKR560, just swapped to a Garrett GT3076 56T with 0.82 housing and a 50mm external gate on factory manifold. Feels so much better to drive now

250KW at 1.1bar (16psi)
