4 Cylinder Jeep Thorttle Body Swap

Hay Guys,

I have a 2000 TJ with a 4 cylinder in it. I have a buddy that took the throttle body off a 6 Cylinder and put it on his 4 cylinder. He claims that it gives it alot more power with out killing his MPG. I was wondering if this really works or if anyone has done this before?

Many of threads about this... "Alot" is open to interpretation. I don't think I would use that term to describe the power gains. I would probably say "a little". It's not going to have to street racing or drifting.

Do a search for "throttle body swap". That should get you more information that you care to read.

The only way I noticed a change in my 4cyl when I swapped to a 6cyl throttle body was when the 6cyl was still attached to the throttle body when I put it in my Jeep.

What I am saying is out of everything I did to my 4cyl to get more power the only thing that really worked was change the motor. I actually get the same MPG with my 6 as I did the 4 since the 6 doesn't have to work as hard.

I did it with mine, I also have a cool air intake with KN filter. with headers and flow master ex.

I did notice a small gain, but like Flattie said, it's no street racer!!

I tried to break my tires loose on wet, rainded on, asphalt yesterday and I couldn't. I have 37's and 5.38's .... SO 5.3L is my next plan. I don't want a street racer, I just want to be able to have a few more HP.
