One word mate, AWESOME! Mods i've got are:
Cat cams
AWT inlet
182 manifold (ceramic coated race spec)
BMC filter
Decat
Exhaust
Superchip
Completely stripped (roof lining the lot!)
Produced 204bhp at the flywheel.
With the new cams fitted, driving around town locally is much more easy than it was before due to the increased low down torque and smoothness of the engine, when you step on the loud pedal though, all hell breaks loose! 2nd gear is an animal and the power is delivered smoothly and not in one big burst, well until you get to about 6k and you really start moving, 3rd gear has improved a lot as well, also thanks to the increased torque!
To get an idea of how quick it is, i had a quick blast with my mates R33 GTS T skyline last night, it's running approx 320hp, and we were side by side at the end of third gear from a standing start (private road of course!)
All in all i'm very impressed and worth it in my opinion, then again my car is a dedicatd track car where i'll benefit from the power coming in higher in the revs.
I'll get some 0-100 vids as soon as i can
