Yeah, we have emission checks here in Tucson, so I gotta work with that. I have the block, crank, rods (Manley Cobra) and pistons, and I even have a couple of different 4V heads to pick from, along with a Termi intake fitted with a GT500 blower. My goal is about 800 "hero" (water-meth injected, cool IAT, ect.)horsepower on 91 octane pump gas, with 600-650 available when not pushing full tilt (limited by how much water-meth injection being used). I figure I'd need about 25lbs of boost to make that kind of power, therefore the compound boost scenario (PD roots blower to give me some low-end until the turbos become a factor).
I'll probably spring for a T56 Magnum XL tranny (or TR6060), but I do have an extra TR3650 that I could use in a pinch (I'd want to update 1st gear with a G-force gearset, but I'd probably be better off spending the $ on the T56).
The V6 chassis already comes with a 31 spline 8.8, so I'll be okay with that. Front brakes (Brembos) seem to be abundant, so I'm not too worried about that.
My lingering question is what ECU to use. I have an '07 4.6 mt ECU, but I'd have to flash the correct VIN into it, turn off the variable cam timing, knock sensors, and whatever else to get it ready for the additional changes to account for the added displacement (only 8 cubes, so probably not an issue) and the boost.
The more I think about it, the more I feel that the '07 ECU is the way to go as it is the closest to working with the chassis (other than possibly getting a '12 GT500 ECU + wiring.
Speaking of which, any thoughts on where to get an '07 and '12 wiring diagrams?
