wrangler throttle body swap

Any one have any info or have done a throttle body swap? I have a 93' 2.5 and have heard from ppl that you can swap a 4.0 throttle body onto it for more power and so forth. Looking for any help!

that should work just fine. the 87-90 yj's have single port injection. the 91-95's have multiport. this seems to be a good write up.

I swapped into mine a few weeks ago.(94' 2.5) I robbed one off an 01' 4.0 XJ.
I swapped over the sensors from the 2.5 TB and used a vacuum plug on the unused vacuum port.
There is a noticable power gain,nothing major.
When you first start it the idle is high,but calms down after a minute or so.
You get a "whistle" at certain RPM's.
I do not believe it really changes the MPG any, But I have not ran it enough to know for sure.
Pretty simple swap, 15 minutes or so.
Hope this helps.
