ive done it. I have a 2001 Grand PRix GT. look on zzperformance.com and go under engine. there is a complete listing of needed parts. i payed alittle extra and had it installed the right way. this way if there are problems i will be able to have installer fix it. nothing is wrong yet. car runs great. got about 75 whp out of it. makes for a awesome sleeper. get al ot of weird looks from debadge gtp owners and also awesome kill stories with GTP's. I also got the 4t65e shift kit. car shifts much harder and firmer/faster. Lucie776@msn.com if you have any questions.
