Convinced my dad to start working on the Grand Prix...
 

... well the title pretty much says it all. :lol: My dad has a 2002 GTP and we are going to start to do a few performance mods to it. We're thinking Thrasher CAI, remove U-bend, and a smaller pulley for starters. I just thought that I would post it, anyone got more advice? :?:

Oh yeah, I told him that they were all mods to help increase his MPG... :wink:

2 of those will increase his mileage. The pulley may slightly hurt it, but not noticeable. A 180 stat is suggested before any of that, and possibly a transmission cooler, as well.

I thought that the GP already had a cooler t-stat, is it the same as the bonneville?

My bet would be a 195.

OK, well that will be on the list for the bonne and the GP, is the 180 t-stat on PFYC drilled?
