J Posted March 30, 2004 Report Share Posted March 30, 2004 they saw 3.0 is too small. Be careful with engine temps.... go with a 3.25 with chip and trans cooler oh and a 180 thermo.. Just for future refrence you might want to check out the grand prix sites Quote Link to comment Share on other sites More sharing options...
Flyby736 Posted March 30, 2004 Report Share Posted March 30, 2004 besides the fact that youll have to run premium gas, and get worse gas mileage, there will be quite a performance increase. Its one of the best mods you can do for the money Quote Link to comment Share on other sites More sharing options...
MaroonRegal Posted March 30, 2004 Report Share Posted March 30, 2004 I think most L67 people go down to about a 3.4" pulley. I wouldn't go below 3.25" if I had an L67, and even with that small of a pulley, I'd probably want to be increasing the fuel in my air/fuel ratio. To use a 3.0" pulley, you're gonna need to do some more serious alterations to keep your engine intact. It's possible, but don't do it.
