I wanted to buy a UR pulley kit on this week. I am getting the Greddy turbo kit in September. When the time comes, will effect the ECU or my performance in any BAD way?

Mike_RX8 :cool:

I have the SR Motorsports pullies on my car. No effect on the turbo kit. I would tell you to save your money as pullies give very little hp increase. Dynoed it & it gave me 1-2 hp. save the money & buy some nice gauges for your turbo kit.

yea, got the pullies on mine before i went turbo, no problems from them , have not had it dyno yet or before so I have no way to know how much hp was there, but fanman knows his stuff so I would listen to him. But the red pulleys (sr motorsports) look good in the engine bay :) But gauges are a better investment, engines cost more to replace.

Or better yet, get a nice set of colder plugs. Helps prevent detonation.
