Best setup for my 2001 2.5 RS

Dtdunk · 09-05-2005, 04:27 PM

I was wondering the best setup for my 2001 2.5 RS. I want to make it streetable while also making it fast as hell. I already have ram air, cobb headers and cams, hks exhaust, and the cobb power pully. Any suggestions?

purty spark plugs?

bore the throttle body?

headwork?

high CR pistons?

short throw shift kit (hey it helps accel.)

"Fast as hell" and RS dont go together. Sorry dude but the EJ25 does not make alot of power, even with extensive mods. Swap the engine for a EJ20 or EJ257 if you want "fast as hell."

EM, like the Rallitek's PP would be a start. Like Nick said, you wont be going 'fast as hell.'

+1 to what Nicklbrso said.

If you want to finish out your ride, do suspension man. Shocks/springs(coilovers?)/rear sway/bushings/etc etc.

You've done most of the power mods for the EJ25. Like svek said, maybe high comp pistons with more engine work or EM. If you still desire a lot more, you just put all that money into the wrong engine. A swap to the EJ20 or the USDM STi would more likely suit you.

Turbo or Supercharger...

either way if you want to be "fast as hell" your going to need 1 power adder
