obd2...
not 100% positive but i think it is a possibility to put an auto ecm on a manual if you do something to trick the computer to think the transmission is always in drive. otherwise the ecm thinks your in park all the time and you have a terrible power loss. i know i read this somewhere on someone's swap thread but i can't remember for the life of me who it was or how he "tricked" the ecm.
What do you mean by terrible power loss? I am having issues with mine but don't want to hijack this thread.

My Jeeps have the class as "AN" on the title, body type model "UT".

All about that unibody life.

Different states have different classes that Jeeps are registered under. Some states may register them as a pickup truck, states like Arizona do not. They're registered as station wagons from what I heard on multiple occasions. Part of the reason Jeeps aren't usually harassed about mud flaps in AZ.

In CA, I don't know what they're registered as. Probably a light duty truck or something, so the engine would have to come out of a Dakota on paper would be my guess. I don't know though, just speculating.
Here in Utah, my Jeep is registered as a pass/light truck utility.

A Jeep with a cammed Hemi, no top and doors, and a dumped exhaust is more pleasuring than sex IMO.

With all that being said, if my 5.2 isn't working, I'm bumping up to a 5.9 like bmgadg has.
I own a 1968 Chevy C10 1/2 ton 2wd. It has the 327 V8 that is pushing out at least 325 HP, and this thing is a blast to drive. So I can only imagine a V8 of its equivalence in a Jeep that weighs at least a thousand lbs. less....oooohh, now I'm getting a woody.

I would love to have a V8 in my YJ just so that I can play with these little piss-ant imports who buzz around me then slow down just to piss me off. I would love to see their jaws drop when a V8 Jeep spins circles around them.

My friends dad had a 383 in his cj but he had 4.10s in it so he would beat beefed up domestic cars to 100 ten he'd get passed because his jeep wasn't set up for going fast.. Just wheeling

Bear in mind a Ricer is typically a stock 4 cylinder imported vehicle with an annoying exhaust can, and many mods that don't actually improve the performance of the car, let alone power output.

I have an 85 Supra with a 160hp 6 cylinder under the hood. Most V8 Jeeps can't keep up, thing moves in a hurry. That's a REAL import

LOL, I don't plan on ever going a hundred in my Jeep, 75 tops. But it would be fun to play with them in town.

Very true, but there are some that are built and tuned to run. I just want to see their jaw drop when a Jeep leaves them in the smoke, or dust. It sort of messes with their super inflated ego. It's funny to see the expressions on their faces when I leave them behind in my old beater looking '68 Chevy C10 "farm" truck.

My logic was that I've always wanted a Jeep and a muscle car. Why not have both in one? Now a 318 is no muscle engine, but it's more muscle than a six shooter.

However, if I ever save up a large amount of cash, 70 Cuda with a 426 Hemi.

Of course I get wood when I see a 1970 Chevell LS6, Now THAT is raw power.

Has anyone seen the specs of the new 2014 Dodge Viper? 640 hp and 600 ft lb of torque The new 'vette only has 450 hp and 450 ft lb torque Proving once again that Chevy is garbage

Back ontopic, I'll be plenty happy with my 220 hp 300 ft lb Mopar 5.2L So long as I don't pay attention to the gas gauge all the time...

All about that unibody life.

My 5.9 gets better mileage then my 4.2 ever did. I get right around 20 MPG.

Well in that case that makes me excited. And I'm going to a 5 speed manual instead of the 4 speed... 20mpg average?

And I also just read your other thread, guess I will have to take careful consideration in routing my throttle cable...
