3.7L motor question

Does the Nitro and the Dakota use the same motor and everything? I looked it up and the duisplacement is almost the same. If there indeed the same i am going to buy JBA 3.7L Nitro headers and see if they fit.

Hmm, not sure on this one... I remember a thread from a different site that said the liberty 3.7 had clearance issues with exhaust parts... I cant remember if it was headers specifically though.

I'd assume the header flanges are the same, but interference with other stuff under the hood (steering shaft?) and meeting up with the rest of the exhaust without custom fabrication might be something to check into.

I was getting a custom y-pipe made anyways. I getting a 6x8 trailer and i need a little more power to tow it. Im pretty sure there is more room under the hood then the Nitro. I guess Ill soon find out

the problem would be where the suspension parts are in relation to the nitro... and the cross member...

Wouldnt you be looking for more torque to pull the trailer, instead of high RPM power? unless its a long trip on the highway, then it makes sense.

first off, see what gearing you have, all these engine upgrades on 6 bangers dont do much, if you have the 3.55, get rid of them, go with a 4.10, that is probably the only mod that will get the truck moving besides a turbo.

It's true. Gears would be the best for towing, much better investment than headers. Keep the engine tuned up, use good fluids, get some gears and let it rev up. Cruising at 3000 RPM doesn't feel strained for the 3.7L, but of course it will suck fuel.
