LS6 vs Fast LSx intake manifold
I heard the LS6 one get 10rwhp, then LSx Fast one 15-20rwhp on LS1 cars.
I can get LS6 off the ebay 400 bucks, LSx Fast 750 bucks. is the later worth it. I mean an additional 300 bucks for 10rwhp difference..
your thoughts please?

I've been trowing around the same question on how to mod my car. It seems to me that the ls6 would flow well enough for a stock setup with full exhaust. But if you anticipate doing a head cam package and throttle body then the FAST would prolly be worth it. That's my .02 on what I plan to do to mine.

right.. that's true. thanks guys, good points, and yes I do plan on doing AFR h and some cam.. no ThBody, but yeah the extra flow will be very benefitial to the h and cam setup.

on a stock engine, you can actually lose h.p with the lsx.
the ls6 manifold has been proven to work with any combo.2000 nhra edition formula

I have been trying to decide which one to go with also. I will be putting one or the other on in the spring. With my current mods which are lt headers,y-pipe,lid, and loudmouth exhaust would i lose power by putting the fast intake on it???

LS6 intake works great for H/C cars even. Still not much to pick up with the FAST.
I went with the FAST on my 402.
It all depends on how far you plan on going in the future.

If you go ahead with the FAST manifold, get the Nick Williams tb and not the FAST tb. The FAST tb tends to stick in the open position (or so I've heard).

I will get the 85mm Fast intake so it should be fine with the stock ThBody,
I'll port the ThBody as well.. in terms of engine work h/cam and yes I'll do a vortech s/c or pro charger not sure which on to choose yet but it will be a blower for sure, maybe the 838 pro..
