Depends on your budget. I've ran a ported LS2 manifold, fast 92 (just removed) and after I get everything adjusted a bit with my steam vents a fast102.

My suggestion is figure out exactly where you want to be, and then choose the manifold for your goals.

A fast 92 or 102 is a pretty nice thing, but do require some small modifications. If you watch my video a few posts down, I did a full diy on a rebuild for one, so if you score a used one dive in.

What I mean is are you planning on porting your heads? Are you going to boost the car?

If no port the stock ls6 or LS2 manifold. Peak speed has a great service and pricing, and you will not notice the difference between a fast 92 or 102 and a ported stock manifold with unported heads. I have ran all of the above on my setup and I can confirm that.

If yes you do intend to port your heads, or you plan on stroking or installing a larger CI motor later on down the road, go with a fast 92 or 102.

You haven't stated if you are ls6 or LS2.

Fast 92 is basically plug and play with an LS6 and requires a spacer kit for LS2 fuel rails. I ran mine with the spacer kit and stock injectors and later on with STS v injectors which are ls6 length.

I prefer my fast 102 over the 92 with my setup. I have a cam, ported heads, injectors, cai, and long tubes with high flow cats. I am using a stock LS2 throttle body.

There are other choices such as the MSD airforce, BTR has a manifold also. Those are for more specialized setups and boost and not particularly good for lower cubic inch motors.

So figure out what direction you want to go, and buy the appropriate one.
