Well, if it is a 99, then I assume it has the same 3.5 motor our VXes have.

You should go to planetisuzoo.com and join the forum there. I have become intimately familiar with the 1st gen V6. I actually just bought a 3.4 motor for it last week. I will hopefully have the 2.8 outta there soon. The late model Troopers share a lot of similarities with the VehiCROSS. Anyway, the Planet is the place.
