Now after doing a little diggin I've narrowed it down. Ws6store sells both F.A.S.T. 92mm & 102mm all together with a fuel rails and throttle body its $1699. However they also sell the BBK intake w/ 85mm throttle body & fule rails for $980

Which one is better?
Is the F.A.S.T. set up worth the price?
And yes my vehicle is all stock right now.

 

You only need to buy new fuelrails for the FAST 102 intake, the FAST 92 and BBK intakes work fine with the stock fuelrails.

 

What are your mods

 

None so far, will I'll eventually have to change out the pushrods and lifters?

 

a thousand dollar intake isnt really a good starting mod. Start with a lid and LT headers, an ls6 intake if it doesnt already have one. get a stall if its an auto.

 

Do this...imo stall should be the first mod on an auto. They're viagra for your car, you'll love it. If not an auto, definitely lid and headers...FAST is for later.

 

This man speaks the truth. There is no need for an intake manifold swap untill you do at least a cam AFTER all the other basic bolt ons. The exception to this is if its an early Ls1 you can switch to the later Ls6 style intake manifold.

 

I gained 21rwhp with a stock engine, and just a FAST 90mm intake. ZERO tuining, so there was more left on the table. Power was gained across the board too!

Its worth it no matter what your mods are.

 

So a thousand dollars for 21 hp
Or 500 for a set of longtubes, that nets more...
Or 700 for cam springs and pushrods, again more than 23 hp

The dollar per hp just isn't there for a fast unless you've already done a lot of other mods or you're trying to say stock internal
