not much done to the car to be honest. gspec crank pulley, n1 cams, n62 maf, nismotronic, 2.25 ss vrs exhaust (will change very soon,) 3" intake @ 18in length, bpi velocity stack, fx500 clutch. i dont think there are any other mods on this motor that i can recall. very very basic stuff going on with this motor.
I didnt retune and afr at higher rpm and maf load was dipping into high 11s which may be the cause of my lost 4hp. lower end power seems to have picked up significantly though. i will be retuning it after work today, and fixing up the exhaust a little bit better.
