Hello everybody, quick question for you all. I am about to finish up my ls1 swap and I wanna keep my stock tb mainly because I dont plan on any more engine intake mods and I was wondering if the Ls1 to Ls2 tb adapter would work, because it goes from 3 to 4. I would rather sound like a dummy on here then buy an 80 dollar part and not have it work. Any recommendations for a good price? Here is an example of what I am talking about:


Suggestions?

 

No it will not. Different bolt pattern and LS4 is 78mm where LS2 is 90mm.
