I haven't seen a 4.0 that are really tricked out. So I would only be speculating as to how much HP they are capable of supporting. But I have seen V6s that are turbocharged with over 1000 HP. In fact, in a Turbo (or maybe Sports Compact Car) magazine I saw a 4 cylinder with 900 ponies. If you got money, it's amazing how much HP you can get out of a motor. Top fuel dragsters are producing in the neighborhood of 7000 HP. Of course they rebuild them after every race

Anyway, I'm completely rebuilding a 1996 4.0 OHV. I'm (with the help of DPS Motorsports) custom fabricating a turbo system for it. I got a good group of talented people walking me through this. I have no idea how much HP I will get but I'm sure I'll be well over 400 HP. Yah yah yah. We heard this story before haven't we?

We can speculate all day long and get nowhere. But here is the plan:
Start with a 1996 4.0 V6 OHV
Forged pistons
Forged connecting rods
High performance head components in a stock head with a 3 angle valve job
Balanced crankshaft
Relocation of battery, windshield washer and various other components to back in a custom built container where the spare used to be.
Custom exhaust manifold coming up and to the front of the engine compartment
Two Turbonetics (Toyota T26 equivalent) turbos plumbed to two custom intercoolers
The two intercoolers plumbed into a single throttle body
True dual 3" exhaust through high-flow cats and Maxflow mufflers
MSD (or other manufacturer) fuel management system with timing control
NOS direct feed system (just to get thing going)
Injectors (30 lb/hr)
Custom hood to allow more air circulation
Of course, this is all talk. I have a huge task in front of me here. I got a few bucks burning a hole in my wives purse and access to some very talented fabricators who are as enthusiastic about this as I am. Well, almost.
But even with all this planed work I wont even come close to an 11 second 1/4. Hell, I won't even be on the same clock. But I should (assuming the transmission hangs tough) have very very fast 0-60. And that, after all, is what I'm after
Anyway, as soon as I get the motor (tomorrow hopefully) I'll add a page to my web site with a step by step. It should be a slow process seeing how I'm not the most literate shade tree mechanic and there is a great deal of custom work being done.
