Ok guys, i have a mate that has spent nearly $40,000 on his RB25. It has a bit of shit done to it this is the list
Areas pistons
Cunningham rods
Metal head gasket
Head work
Deaek bottom end and bored
Blue print and balanced
N1 oil pump
N1 bearing kit
GT 35-40 garret turbo
Massive FMIC
Custom plenum and throttle body
MSD DIS4 ignition system
Ltx 12 microtech.
Now it was dynoed at 360 rwhp at 19 psi, i thought with all that work it would make at least 450rwhp plus.
I notice alot of other Skylines with not much work done coming very close to 360 rwhp.
Is it time for a new tuner or is that it.
What do you think.
