Thanks for the info, For what I can see, it's going to be much cheaper and reasonable to buy the VR4 engine with all the goodies rather that the truck motor and add them. What I want is more acceleration at times but also more torgue for climbing. I am not wanting to pull down a building or anything, just a little more power to climb up some steep hills when off roading on the trails at "Telico" mountains in Tennessee with out any problems, so my understanding is just the fact of having the 24V DOHC will do enough for me for the climbing and just rely on the turbo boost only for speed since the turbo's don't do squat at 1k rpm and under.
