Is there an agreed upon best TB for ls1 stock cubed, h/c with the 102 yet?? I have read through countless pages on TB's for the 102 intake.. Some say get
NW 102 tb while others note tuning issues on idle/low rpm?.... Others say get
A ported 92 tb... Then it seems also that the stock ls2 tb is also good, but requires electrical adapter harness and porting.... So on a stock cubed, afr205, mid size cam, yell a terras, fast102, 48#'s, upgraded fuel system car..... Is there a general consensus on who is the overall winner or best choice TB to work with new 102?? Looks like I am leaning toward a SD tune to avoid the MAF issues and cost, is that a good idea or bad idea? Car is not a d/d just a toy, so some drivability can be comprised slightly.. Thanks..

Unfortunately no, all 102 tbs perform the same at WOT, however the difference in performance is getting to WOT, and there isn't much power to be lost in the between time.
I'm going to get the FAST 102 TB, they supposedly fixed the sticking blade with dual TB springs, so hopefully it'll be well worth it.

havent seen issues with NW throttle body's. I know the FAST units had some issues that may have been worked out. But I like my NW 92, its a quality piece. Going SD wont be an issue as long has the tune is spot on, you will notice some driving differences when there is a change in the weather. But since you dont DD the car i dont see any problems.

The FAST throttle bodies are the way to go. I've seen too many NW and others not seal the intake. this is because everyone designed a throttle body and FAST designed throttle bodies to fit the manifold
The FAST 90 mm throtle bodies are the ones that had sticking issues. the 92 & 102 throotle bodies are a 100% redesign.
No one needs a 102mm, but if you get one the FAST has a build in convelute to help with tuning and low speed throttle control.

I mean didn't u port the back of the TB to match the manifold inlet , or did u use the "ring" .

Ive seen the thread about the ring and asked this...
I run a GM LS2 90mm DBW throttle body on my FAST 102mm and dont notice anything.
Here is what I always came back to, when you install that ring, there is the same edge. Its now just farther back. You would have to make it with a bellmouth or trumpet and have the tapered part inside the manifold to get rid of that edge.

Is there much to be gained with the 102 on a stock cubed ls1/6. To get all the benefit of the 102 wouldn't you need to increase the size of the MAF and intake duck? I am piecing my build together and the local tuner doesn't like after market MAFs so why restrict then increase size? What is everybody running?

I went with the V ring.

A 90 or 92mm, with the 85mm Vette/truck MAF, is plenty of 99.9% of people.
This intake will make 20-25hp over an LS1/LS2 intake and 10-15hp over an LS6 intake, on a totally stock engine.
