Best and cheapest ways to get more power out of the 4.0?

swap in a SBC. really think of how long jeep ran the inline 6 without any major changes. It is pretty much at its limit unless you are doing big stuff like cams and stroking it or F.I.

Cheap stuff like injectors, air filter/ intake, better header and exhaust, throttle body. 99up intake swap.

Mopar 703 Fuel injectors off a Dodge Neon 2.0 will help with throttle response, not to mention you'll have CLEAN injectors too if you prep them right.

Its got an aftermarket heaser, not sure what kind, and an after market exhaust. I like the idea of those injectors. Will boring it be worth the effort?

Unless a complete setup is done - meaning built stroker your just gonna get little extra horses here and there

No. Because to bore it, you have to completely disassemble the engine and you might as well rebuild it.

Woahhhh. That sounds nasty.

Sounds like a tractor. Wish the person would have revved it.

The_ocho

Sounds like he is running an open header. I doubt it would be that choppy with a full exhaust

X'S 2 on the open header. There are also the acoustics of the building that are enhancing the sound.

Pro tip:
Noise makes noise, not horse power.

(I did like the disappearing odometer when he started it tho, pretty slick.)

Mine sounded like that without a muffler and a stuck valve! I agree:Noise doesn't mean HP. My 8HP lawn tractor is really loud!

I watched the full vid on YouTubs, that's him turning on the head lights, odo dims
