hey guys im wanting a new tb bc im told that the 2.4 tb sucks with the sc any thoughts about the ls4??

 

There is a kit on ZZP for the LSJ. Not sure if it'll work on the LE5 though.

 

i thought i saw on zzp's site they had one for the le5.

 

the one for the le5 is for the stock lsj and if you are supercharging with the lsj supercharger it would work because you have the lsj intake mani so for your supercharged 2.4l it will regular 2.4l it dont think it will

 

i'm reading that as he's already put the m62 on his car and doesn't want to use the 2.4 tb. in which case yes, you can run the ls4 with it

 

lol thanks all i wanted to know

 

Would there be any point in using a LS4TB w/o F/I over using a LSJ TB?

 

yea it has a wider opening so it allows more air to be pulled in

 

So I assume it would yield better gains then the LSJ TB even on my N/A engine?

 

yes that is right on zzps website they have the specs on the 2.4l tb compared to the specs of the lsj tb i dont think that the ls4 tb will work because on zzps website they said you have to port the intake on the lsj to make the ls4 fit and seeing that we have plastic intake manis i dont think it will work

 

ahhhh, so in order to upgrade to the LS4 TB I'd have to get a bigger Intake manifold?

 

thats not good to hear....

 

no...you wont see gains on an N/A engine. the stock TB is not a restriction at those power levels.

to the OP, you can run a LS4TB, but it will require the same rewiring that the LSJ TB does

 

actually the throttle body is a restriction it shows on zzps website that the 2.4l tb is smaller than the intake mani so using a bigger tb is going to free up some horses maybe not much but any gain is a good gain just bought an lsj tb and gonna buy the adapter next week to test it out

 

Anytime you allow the car to breath freely(or forcifully), you will gain more hp.

Although the 2.4TB might not necessarily be a huge or even a moderate restriction, its still a restriction.

 

well will i need to port the sc??? for the ls4?

 

according to zzp you will there is a how to on here

 

If you don't have a ls4 tb spacer then yes you do

 

RAW sells a spacer for like $50 or so

 

holy crap i didnt know there were othwer ppl from oklahoma here

 

I couldn't use the ls4 tb on my car. There was no way it would fit with the intake. The spacer plate just messed things up and the abs got in the way. Ended up having to trade a local member straight up for his lsj tb so we could get my car completed. I have an 07 auto, and apparently the engine is pushed forward some which would cause fitment issues.
