Well, I've finally gotten fed up with the 2.6l slushbox combo, and I'm ready to move on to bigger and better things.
I'm about to attempt the 6g72 SOHC swap in my second gen power-ram 50, and I'm bringing the montero's 5 speed/transfer case along for the ride. I've heard that this swap isn't too unusual, but my further plans for the motor probably are. I want to twin-turbo/twincharge the thing. I've already picked out turbo's and a supercharger (the turbos are from a vr4, and the supercharger is a Paxton SN89). Reliability is sure to be an issue here, but I'm not afraid of fabrication, and I'm not shooting for crazy hp. Whatever power the final build makes will be plenty, and my primary concerns will be cost (within reason) and reliability (also, within reason).
For the swap, I'm expecting the need to fabricate/replace:
-A one piece intake manifold
-Both exhaust tracks
-the intercooling system
-any parts needed to prevent interference
-any parts needed to install both of the turbos and the supercharger
-most of, if not the entire, electrical system
Basically I was wondering what kind of issues that I might face, which parts will be prone to failure, and what I should also replace to maximize reliability.
I'm hoping to stick with the SOHC, and it needs to stay manual and 4wd. Any alternate turbo or supercharger suggestions would be appreciated, as I am new to forced induction (though I understand the concepts). Once again power production is not my primary concern here, a semi reliable 350hp truck would be better than a 1000hp self-destructing monster.
Here are a few pictures of the thing for reference:
As the project gets off the ground I'd be happy to post pictures of the process for those who are interested. I'm also part way through swamping a dodge raider dash into it.
