Hey guys, I am about to pick up my new DD, which is a 97 Tj with a 2.5.
I have been spoiled to 4.0's in all but one of my xj's, so I know that thing is going to be a total slug.
I had read that you can put a 4.0 throttle body, and a spacer on the 2.5, and grind out the intake to match the bigger throttle body, and use the ford 19#
Injectors to get a little more out of it powerwise.
I've also mostly read that throttle body spacers are a joke, and are about as effective as a 3" body lift. Which opinion is right? I just want to be able to drive the Tj on the highway with 31's and the stock 4.10's. nothing fancy....
EDIT: BTW, I know it isn't an Xj, but the same physics would apply, since it is the same 2.5 that many xj's came with. No need to ban me from Naxja or anything. It's just that in my experience the average Tj owner will put 37's on a 4 cylinder with a Dana 35 and rock that motha. Not me.
