Default FAST 102/NW TB vs....?

Hi Folks,

I'm building an LS3 418 stroker and am trying to determine what path I should take regarding an intake/TB. I was planning on going with the FAST 102/ NW 102 TB (based off an LME build I saw a year ago)...however my engine builder seems unsure about that, instead suggesting to just use the LS3 intake and TB (ported I assume?). I know the FAST/NW will run ~1300, but if folks more experienced with this could chime in I'd appreciate it.

Thanks!

The engine builder can build his own thing, or go his way if you can live with the limitations, every one who uses this combo could have saved the money and use the cheap stuff, then I don't see any body selling their choice combo to go back the money saver.

I assume you have LS3 heads? If so, go LS3. No real gains with the FAST over the LS3. The FAST is worth it on the LS6/2 and LS7.

Ur statement is incorrect! If he had a stock cubed block(lets say) ls3 then yes the fast would have minimal gains over stock ls3 but he's got a 418ci that FAST will have a nice gain they work great on bigger CI engines! Now if he got cnced heads or aftermarket heads
That's a plus.

An ls3 with very mild head porting and cam I sold the guy a Nick Williams 102 TB and he got himself a used fast 102 intake which had a very bad ports miss match, we believe is was an ls7 intake cause the ports were much wider than that of the ls3 heads, long story short 40 Whp gain on pump gas and 30 torq, over the factory intake and Throttle body.
