A Comanche would be crazy with that much power. I bought my first wife an '87 2wd sport w/2.5 4cyl and that truck is so light I could roast the tires and drift corners.

I'd say it opens up a whole new can of worms and get have quite a bit of power with not a ton of work, and NA vs what you will get out of a boosted 4.0 which probably won't be much more than a stock 5.9. Yeah a boosted 4.0 would be sweet. But it's just not my motor of choice if I want any power.
First off, let it be known that the 5.2 is way too big for the ZJ as it is. The amount of **** I had to cut to get the V8 out of the donor is ridiculous. This lack of space means there's nowhere to practically put a supercharger, or really much of anything into that engine bay. Your only options are to go NA. Maybe you could get a remote turbo in there. The stock niner makes 245hp from the factory, on 93 octane. You can push this to 300 with some effort. The 4.0 makes 185hp on 87 octane, but I figure with some doing, I could get it to 300 on 93, just the same, but with some creativity instead of an additional 2 liters of displacement.

With the 4.0, you can stroke, port, super, or turbo, and still have room in the bay. That leftover space means a damn lot when you're actually working on stuff. Plus you can't have a sleeper with a 5.9, especially if you run forced induction on it. You'd have to cut the hood open for the blower. Subtlety is important to me as well.

The 4.0 leaves you more options as a Jeeper, and has pretty much the same level of options for actually building the motor than the V8s available, meaning you do have more options for it.

All I wanna know now is how am I gonna make a 42RE hold the kind of power I want?

Fitting a blower on a 5.2/5.9 is certainly doable, it's been done quite a few times before (centrifugal blower, or the Kenne Bell roots blower sitting next to the engine and ducted, although that one required cutting the cowl for clearance). The 4.0 does have tons more room in the engine bay though, working on certain things on the 5.9 is a royal PITA, and certain mods require getting creative with placement of stuff.

The 4.0 is a bit more expensive to build for higher power though, and the parts options are more limited. It can certainly be done though.

For the trans, talk to Martin Saine. He's the guru of the 40 series torqueflites.

I was doing every bit of 85mph in a 45mph zone...true duals were screaming, redlined in first and second.
I'm guessing the guy couldn't drive for ****, as an SRT4 should definitely be faster than that truck.

I can think if at least 15 guys off hand with supercharged 5.9s. A lot of them have kept stock hoods. There's at least one twin turbo in the works. You just have to get creative.

If you took that creativity you want to use on the 4.0 and applied it to a V8, you'd get some pretty impressive results. No replacement for displacement haha.

And Martin will get you anything you need as far as transmissions go.

I was gonna say go tell the guys on the speed freaks they can't supercharge a 5.2 or 5.9. Battery has to be relocated to the back which is better for weight distribution anyways. And the fuse box under the hood is rotated so its parallel with the fender. And then your golden on space for a blower

I'm pretty sure a couple people have been able to keep the battery up front by moving the PDC and spinning the battery sideways.

If you had to cut **** to pull a V8 out of a ZJ, you're doing something wrong. I just pulled my 5.2L without any problems.

There's no way in hell a SRT4 is faster than my truck that's built. 4.88 gears, Plenum has been fixed, intake has the kegger mod, A/C delete to free up a few horses, hi-flow exhaust, performance PCM.

I've beat plenty of cars in my truck and ZJs. Mustangs V8s and V6s, Firebirds V8s and V6s, a couple beamers, among a few other cars.

I live, eat, and sleep magnum motors. I know just about everything about them and how to build them, internally and externally.

Didn't know it had anything else done to it. SRT4 was definitely stock though, considering I'd guess that truck ran mid 14s at best? An SRT4 will run a 13.9 stock with a good driver and good tires. Keep in mind, my ZJ, which is definitely lighter than a RAM 1500, won't run better than high 14s with 3.73s, 29.5" tires, upgraded heads, mild cam, tune, exhaust redone from the manifolds back.

I'd guess my truck would run around low 14s or high 13s.

SRT4 had alittle bumble bee exhaust and who knows what else. He kept up with me off the line, but once I got to second gear, he was looking at my tail lights. Also, I have procomp mud terrains with American Racing wheels.
