LS2/LS1 intake

are these intakes interchangeable on the LS1? If so is the LS2 a 90mm?

Yes, but the LS2 does not perform as well as the LS6 unless you have it ported. Best getting the LS6 IMO.

so an even better setup would be fast 90 with a ported and polished LS2 t/b?

yes but unless you have all the supporting bolt ons, a healthy cam and heads, you are wasting your money.

Great article. It looks like the LS6 intake w/90mm TB is the best bang for the buck. No doubt the fast is the best performer though.

There is a new one due out by Weiand but it is months late and no results on it yet. Might be worth looking at to see if you want to wait for it over the winter.

If you look at the tpis testing the ls2 intake and ls2 90 are a very big cost effective improvement over the stock ls1/75mm t/b I would have to say bang for the buck the ls2 is the way to go and also this is unported Hell Ive seen ls2 intakes go for 150 while the ls6 may have 5-8 hp on the ls2 in some areas Bang for the buck you cant deny that the ls2 is your best bet Hell I just noticed that it actually outperforms the ls6 at 6600 and that is about where I want to shift

Obviously if you have an ls6 intake your not going to switch to an ls2 but if your like me with an ls1 The ls2 has a large hp/tq increase over an ls1 intake..
it would be nuts to buy a ls6 then spend money to put a 90 t/b on then i would go the fast route

I had a ls2 intake and t/b put on my ls1 and picked up about 40 hp.
But that was at 14+lbs of boost.

Seriously it the best bang for the buck. Split the fuel rails and make the balance tube longer(steel braided line). And buy the t/b wire adaptor. You can even still use your ls1 frc.

yes going with big cam, want to make power all the way to 7000. This is a road race LS1 stage 2 TEA heads, dry sump, forged bottom end, 42lb injectors, etc. Just need to get this intake dialed in
