Throttle body changes

sjx40250 · May 25, 2005

I know there was a significant change i the throttle body used from 90 to 91. Was there a change since? I bored out my 92 and love the results and I am picking up a 97 GC with the 4.0 for free and would like to do the same thing since I have a spare.

Should be the same, no changes. The TB on my '99 is identical to the one that was on my '94, '91, as well as my parents '95 4.0 ZJ...........:lecture:

Hey fellas,

I have an '01 XJ 4.0L, I've thought about replacing my OE TB with a "performance" model. Will it make much difference?

Also, what is your take on TB Spacers?

Well almost everything! I picked up my 97GC and found that the MAP sensor was moved to the TB from the firewall. Don't know when this happened, I suppose around '96 when the ECU and OBDII was introduced. So I think the TB from 91-95 are different then those from 96-01.
