ok im getting the s/c setup from a member on here and im doing a s/c swap into my 2.4 i was just wondering would it be possible if i could use the 2.4 throttle body instead of the lsj throttle body??? lmk thanx

 

I'm pretty sure you can but there are a couple of reasons why its not done

1) TB is smaller than the LSJ unit so it becomes a restriction that you don't need...

2) There was some concern about a vacuum hose that normally connects to the LSJ throttle body (although this can be tapped somewhere else)

and I'm not sure about the bolt pattern...technically I believe it can be done.

 

soo i should jus get a lsj tb??

 

i would

 

no need... read becks build and he tells you how to rewire (very basic) and just bore out the holes a lil

 

hmmm alright but i was also looking at the ls4 tb lol

 

u need to port ur s/c for the 4.2 tb

 

port my s/c???? well a lot of ppl say ls4 is good

 

it is but to u have port it so it will fit.

 

how much is it to port

 

not sure. u can do it ur self this might help.

you dont HAVE to...it still bolts on fine. It just wont flow as well since there will be an uneven surface. I would get a LSJ or LS4 TB though, because using the stock 2.2/2.4 TB requires you to drill new holes for the screws and it wont flow as much anyways.

 

alright thats what i was thinking lol how much u think ls4 or and lsj tb is????

 

used, probably pretty cheap. definitely sub $100. Find a member who upgraded to the LS4 TB and buy their stocker

 

alright i will thanx a lot hunter

 

ls4 TB $100

thats the ls4 tb??

 

yep. yes it is. I will warn you though, you will have a sensitive gas pedal if you install it, but if you ever pla on running more than 300hp, you'll probably end up getting one anyway. Your call.

 

oic ok thanx im doing a 2.4 s/c swap can i use the alternator on my 2.4 for the s/c???

 

yes you can. the only parts you will need to make the belt system work are the LSJ tensioner and the LSJ idler

 

yeah you can use the alternator... im pretty sure you just swap the wiring if im not mistaken

 

hey glen what u got so far??? i got most of it well i wont get it till march but i still need 2.5 map/intake temp sensor and i need that pigtail and i need the intercooler pump and injector harness i need to find one of those lol and info u can give me where and how much this stuff is??
