2.5L

Let me start by saying that this engine is not worth the money that you saved by getting it vice the 4.0L. Although it does do well off-road it is horrible on the highway. I have added a K&N air filter and a Borla header to try and improve it's performance. This was all before I realized that this engine is not worth the price of some of these mods. I got a fairly good gain at the top end from the Borla but it still wasn't enough to get over those California grades in 4th. I was stupid and installed the header myself, man what a pain, It is definitely worth the cost to have it done. My advice is, if you have this engine swap it out with a 4.0L or a V8. Don't waste your money on all of these fancy mods because they aren't going to help. Click on the image to view it full size.

 

Four cylinders short of a real engine!
