You wouldn't feel a 2.5". A 2.4 would be ok, probably worth 10hp and maybe 15 tq. 2.3" would be probalby 15/20. The only thing required for a pulley swap is a custom intake to support the increased flow. Exhaust and a 180 stat are desired. No PCM changes necessary.

After tranny number 3 (hopefully that doesn't happen while I own it) I'm gonna put a 5 speed in it, this particular auto sucks for reliability with any decent amount of power.
Good luck with your tires and pulley. You're hooked now, theres no stopping you. Its way too much fun to mod these cars. I just put a pulley on a '04 Monte Carlo SS today, the owner was slightly impressed to say the least, now they want more.

My cousin has a 2000 GTP and dynoed 242hp/ 274ft-lbs of torque to the wheels with a Homeade CAI, 3.4 pulley, and U-bend removed (stock exhaust).

Thanks
In fact I remember having this discussion in another thread some months ago with Shawn(dbtk2) who was real informative about which pulley to go with. ----thanks Shawn---

Always glad to help, and I'm glad you're satisfied with your decision. That car should run very well with that setup, and the nice thing about it is you don't have to worry about doing mods to get rid of KR.
