I know 2.5l performance is a joke but im trying to get a few more precious hp to hold a constant speed on the highway.
I read several places that a 4.0l throttlebody will provide a bit of power, has anybody done/heard of this?
What year is comatible with the 97 tj 2.5?
Please let me know with as little jokes as possible :-X
Thanks! ;D

They provide a little more power but nothing crazy. Any TB from a 4.0L should work but I am not sure if they changed in the later years. When I swapped mine I used 4.0L sensors when my dad did his, he re-used his 2.5L sensors and no difference. The TB used to be $50 at Jeepstuff w/o sensors and $100 w/sensors
If you want more performance, open up the exhaust, it made a huge difference on my 4 angry squirrels

i put in a 62 ml tb and spacer.
great throttle response now, and definitly allowed for better breathing. noticible in the nigher revs.
i think my next upgrade will be mustang injectors and or a electric fan.
but make sure you get the correst year because the sensors are in different spots.

2.5 performance ? , hardly a joke , there's some potential in these engines and they are tough.
What works is
Gears , 4.88's or 5.13's depending on tire size chosen.
4.0 throttle body
Cold air intake
Free flowing exhaust and or header
Electric fan
Cam
Head work
My 95 has all of this , except the cam and head work , this may happen later , I've got a spare head 8) , this engine needs to be , um ..... freshened.
