Now see, that is what I was thinking too. I'm looking at doing bolt ons mods to increase HP while still keeping the powertrain warranty. Thus no internal work. I didn't think a pulley would cause any harm, especially if I am not spinnning it as fast as I can each time I drive it.

I did the CAI & tune in my 09 1st, & felt a huge difference. Then I did the pulley & felt the same difference all over again.
Also did FRPP M-5300-L springs. Perfect stance w/19" wheels IMO.
