So I have done tons of searching and cannot find a clear answer. I have a 2007 LT with a 2.4 Intake manifold and the stock 2.2 Throttle Body. I understandto go with a 2.4 (LE5) TB or LSJ TB you need a tune. My questions are as follows:

1. Is it even worth going with bigger throttle body? (I plan on getting a tune anyway)

2. If yes, is it worth going LSJ Throttle body or just sticking to the 2.4 (LE5) throttle body?

Any and all input would be greatly appreciated

 

scroll down to the 2.2 N/A and tell me if its worth it.. more air/more power

fair enough, you have already been a great help the question is what are the differences between FE5 and LSJ and who is running the LSJ currently on their 2.4 IM on their L61

There is no Fe5 throttle body... 2.4l is le5 engine, Fe5 is associated with 2.0 SS balts suspension. Upgrading the throttle body only, will give you minimal gains. Get fully bolted and then get an lsj throttle body and tune

 

**typo, corrected


also I will be fully bolted prior to getting my tune; should i get the 2.4 TB or LSJ TB, thats really what im trying to find out

 

I would if i were you. You can buy new from rock auto for under a hundred bucks, make a harness for it to work and you will see better gains. More HP and a ridiculous throttle response

 

zzp makes the adapter plate for the 2.4 mani, 6 to 8 pin wiring harness, and the LSJ TB all in one package

why are you bumping? you already got your answer...

 

lsj TB ll be good when you get cammed

if not le5 ll be just fine for your application

 

I had the adapter plate with the LSJ TB and i liked it
