    Rahtd suggestion is great, V8 is great too. Parts are easy to come by either and especially on American made products which are cheaper as well. Every build is different in my experience of watching them being done here and to pin point exactly what to do and not to do is very hard to put down in a parts list. Decide what will make you want to build it and go for it. We can help and support you all the way through. Keep them build photos coming so we can watch too!

    Nice truck!

    Thanks guys!

    Quick update. I'm omitting the supercharger for now as there simply isn't enough room under the hood of my truck for so many components, and sheer complexity of such a build would be a bit beyond me. I'm currently looking into water/methanol injection.

    The good news is that I found my donor vehicle for only $1000; a V6 Gen 1 Montero 5 door with an automatic. The real kicker is that he's just going to throw in two 5 speed trannys w/ transfer cases, most of an overhaul kit for the 6g72, two bouncy seats, and (wait for it) THE TWIN-TURBOS AND INTERCOOLER OFF OF A VR4!! This guy is the real deal, he's been building raiders and other vehicles with the 6g72 for years and he was ready to move off some of his accumulated spare parts.

    Here is a revised list of what I'm going to do to get this thing up and running:
    -Fabricate engine and tranny mounts
    -Swap out wiring harness for the montero's
    -Fabricate both drive shafts
    -Fabricate Turbo manifolds & run dual exhaust system*
    -Make necessary modifications to the interior to facilitate a manual transmission
    -Figure out how to mount the Raider dash**

    Time gap (the vehicle should run and drive by this point)

    -Swap out ECU for programmable ECU
    -Run intercooler piping
    -Make necessary modifications to the throttle body
    -Swap both axles & drop gear ratio
    -Set up boost controller (I'm shooting for 1 bar ~15psi)****
    -Set up water/meth injection system***

    *I'm planning on hooking up the turbos to the exhaust but not running the intake piping, thus leaving the engine NA for a few months of daily driving. I have it on good authority that this is safe to do. Advise would be greatly appreciated here.
    **I'm in desperate need of a 2nd gen interior wiring harness diagram (I'm looking at you Brad). The Haynes manual didn't cut it.
    ***Still on the fence about this one.
    ****As far as I can tell, this truck should make between 270hp and 310hp at those boost levels

    As I mentioned before, I'll keep you guys updated with pictures as progress occurs. Thanks for all of the support so far.
