I've got an edelbrock 90mm tb from an old project. I'm wondering which intake I should use. I was going to go with a fast intake but recently saw the TPIS ls6 with the 90mm opening. open to all suggestions will be full bolt ons heads and cam in spring

What is the TPIS ls6, eric

I have used a TPIS 90 (resnouted LS6) as well as a FAST 102 on my LS6, both with a 90mm LS2 TB.

I would put it on a FAST 102 if it will fit and seal.

you can find a used fast 90/92 intake for $650.I believe there are some alum intakes your TB will work on for $399 new.

how do you get a fast 102 on an ls6 intake or a 90 mm

Let me clarify- I have used two setups on my LS6 motor. One setup was the TPIS 90mm intake manifold with an LS2 90mm throttle body. I then switched to a FAST 102 intake manifold and used the same LS2 90mm throttle body.

Of the two setups, I believe the second one is better.

Ok i understand , so tpis can resnout an ls6 intake to fit a 90 mm tb , is it worth it, wouldnt the plenum volume just not be there , eric

Well I did pick 15hp using the TPIS which is not a bad deal if you already own an LS6 manifold to serve as a "core" (Cost about $350 for the mod). If you have no manifold the TPIS cost is $850 which makes the jump to the FAST 102 intake a much better deal. The FAST 102 does have more plenum.

thanks for the info. i'll prob. go with the fast 102 at least there is more room to go with a bigger tb later if for some reason a 90 becomes to small
