Im selling my 95 JRSC'd GSR if you want to skip a step

Heres your method for mayhem:

OBD1 GSR
JRSC
Hondata 2B Boost
Hondata intake manifold gasket
Kamikaze 2.5" header
Carsound 2.5" Cat
2.5" Exhaust
JR Boost upgrade pulley, CRV pulley, whetever floats your boat to get you to 8-9PSI.
3" Short Ram Intake

With the proper tuning, you shouldnt have a problem hitting 250whp with that setup.

In terms of getting that power to the ground....
Definitely a nice clutch (ACT HDSS)
Nice tires (whatever you can afford, Kumho 712's to Falken Azenis' to Toyo T1-S to Bridgestone S-03's etc etc)
Good suspension (again, this is all preference)

Just in terms of making power...the above equation can net you 250whp without nitrous...add a small 25 shot and you're definitely in business...
