Good thing I didnt buy and LS2 intake for my swap, the LS1 was only $30

The LS6 intake manifold is a very strong piece. It is a much better manifold for a stock, slightly modified, or all out cathedral port LS engine, IF you send it to TPiS and have them convert it to use a LS2/LS3/LS7 90 mm throttle body.

I had mine converted and with no other changes, except tuning, my bolt-on only LS6 showed the following improvements. Yes, my engine was tuned before the installation of the 90 mm throttle body:





TPiS, the company that does the conversion of your LS6 manifold also did some back-to-back testing of a convertered LS6 - 90 mm manifold versus a 90 mm F.A.S.T. manifold on a highly modified LS engine:




The price of the TPiS 90 mm LS6 manifold is approximately $350, with your LS6 manifold as an exchange.

^^+1 i did the same with my LS6 intake. i sent it to TPiS. the price is just right.
furthermore, i put a NW 92mm tb against the snout, and it was not that much to make it match.

i did a lot of research, and also came across the above table of TPiS's back to back test. this led me to getting the ls6 intake modded by them. great people to deal with as well.

i ran it with the 92mm on my 418, and with cyl 8 leaking coolant, it dyno'd 507/484, with 450 rwtq at 3k rpm!

imo, and honestly, i think this is the way to go.

Wow. Way to bring back a 8 year old thread to debate that the Ls2 intake is junk.

Yep and that stock ls1 intake is crap too

LS6 or fast are the only way to go if you arent going carb style

Well, I guess since I've been researching this I might as well bring this thread back to life for one quick piece of info. Also, it's only gone 4 years untouched (since 2012) instead of the previous 8 years before someone became the "Thread Digger". I guess it's my turn now lol...
