FAST 90 Intake to 102 Intake ,Thoughts? I have a 408 in my 2000 Trans Am,I currently have 90/90 set up.I was Considering upgrading to a 102 intake.Would I see any gains or is it even worth it? What are some of your thoughts?
i think there was a test done already on here, vengeance did it maybe. but they switched from a ported 92 to a ported 102 with the same 92mm TB, and picked up 8hp, so theres no telling if you also go with the 102 (hear theyre hard to tune....idk!)
also to remember, the 92/92s flow around 280cfm(iirc) so even if you do have heads that flow 320...the 102 still might hold you back....idk, it was an interesting pat g read...

We picked up 10 rwhp on my 440 when we put the 102 on with the 90mm TB. We may get a little more with the 102mm TB but who knows. I'll post up in a couple of weeks when it's done.

My current 90 is Not Ported I gained 20 rwhp right out of the Box vs the LS6 intake this was on my H/C 346. Now i am a stroker and I feel I could use the extra breathing...Thanks LS1 Tech Stories

From what I've read, you should see some gains. The 102 repsonds better to larger cubes, if you gained 20 from an ls6 to a 90, then another 15-20 from a 90 to a 102 seems possible. Plus you could sell your 90/90 to make it worth it.
I would have thought the same thing but that doesn't seem to be the case. Seems people are only gaining a few hp form the fast 90mm to the fast 102mm. I do agree with you though. Isn't the opening of the LS6 intake a 78mm? But they are totaly different designs to.

switching the intake alone, and sticking with the same 90mm tb is pointless. you may see a few hp just from the throat of the TB opening being bigger, but the runners and such are nearly identical.

the intakes themselves are nearly identical. the only difference is the TB opening.

FYI, I opened up my 92 to a 96 with a 96 throttle body and seen a ZERO gain in anything on the dyno. If you already have a fast I really do not see a hp/dollar gain. Just makes no sense IMO.
Ive had both styles, and naturally I have to take them apart to see whats inside and they are 100% different. The old LSX was a three piece design. The new LSXR 102mm has individual runners, its totally different.
I went with the 102/102 setup.. No reason not to for the price. You can get a brand new 102 intake for 800 shipped.. Or you can get a ported one for 920 shipped. Kind of hard to beat that if you ask me.
