Q for those who swapped in a stick shift into a newer (97+) XJ

[Kejtar]

how did you deal with the comp? did you use a donor? did you kee pthe old one? did you modify it somehow?

[Safari Ary]

what's a "comp" ?

[Lawn Cher']

Do you mean the computer, or PCM (Powertrain Control Module?) Why not swap the old one from the wreck with the tranny?

OK.. now I'm starting to get confused: I thought that the computer and PCM were the same thing? Also I was told that the smog equipment is different in the 97 and 98 thus I might have problems swapping a pcm over.

I know a few people here did it... where are you hiding at?

They are the same, I was listing both terms. I should have said "aka" instead of "or."

What smog equipment would be different? Both have 2 O2 sensors, and both of yours should have CA emissions, no? I don't see a problem, especially since you have both vehicles there and should be able to mix 'n' match enough stuff to make it work.

I sure hope so.... I looked up the parts in the chrysler parts catalogs and was also told by someone that they are different as well, but I hope that it's just a part numbering scheme change (they have different length/nomenclature) that resulted from the DCX merger. Worst comes to worst I could swap EVERYTHING over, but I'm not looking forward to that. Btw, I know they changed some things between the years as the oil sender has a different plug on it.

I wouldn't be suprised if the part #'s were different but they were the same, when I was looking for a hood the part #'s for them were different from 97 and up, as well as the price, $100 more, but when I threw the hood off a earlier model Cherokee it was identical.

I meant the terms "computer" and "PCM" are the same. I can't guarantee that the '97 & '98 models are the same. It would make sense that they are; even if they aren't you should be able to make it work with the stuff you have on hand. I don't think it would have to go as far as a complete engine swap, just some bolt on parts if anything.

Who's on first?

I sure hope so!

All emissions parts are external to the engine itself, so why would you have to swap the entire long block? I don't think there is anything to fear here, dude.
