2.5L

[95Jeep]

Does anyone know how much horsepower a 4.0L throttle body swap into a 2.5L gives you. And does anyone know cheap ways to get more horsepower out of a 2.5L.

I have the same problem man. If you find out anything let me know. I want to do the same thing. Also going to an Electric fan to free up some drag.

Don't waste your time and money trying to get extra power out of a 2.5. Save your money and regear, that's really the only noticeable difference you'll get. I've tried an intake, a catback, and a jet chip. As soon as I'm done with my longarms I'll be redoing my exhaust utilizing a factory style muffler. Then I can honestly say that all of the things that I mentioned have been removed, because none of them honestly made a noticeable difference. Don't waste your money or time.

Snake Oil! It might give you .42 more HP, trust me. I have tried everything, or some variation there of, under the sun from TB to air tube to electric fan to inertia weighting and more. The ONLY thing that is going to help seat of the pants is lower gearing!

Not much. I may have felt a little more mid range torque, but that's just a seat of the pants assumption and maybe a little wishful thinking.
