Fast 92 vs 102
Need to pull the trigger on an intake, and I'm having a hard time deciding between these two. The install complications of the 102 concern me, but I also don't want to leave hp on the table.
I have not seen many dyno comparisons between the two. How much hp difference does everyone think there would be?
(This would be going in a 98 Z28 - stock displacement, big cam and trick flow 220 heads.)

It really depends on what you want to do with the car. If this is a street machine, I'd say the FAST 92 is the one to use. Fewer installation problems and you can use your existing fuel rails and injectors. If you're going all out for racing, then the FAST 102 might be a better choice.

My fast 102 was worth 16hp over 92. But it was a vengeance ported one and also on quite a bit larger engine than stock.

I've yet to see a cathedral msd outperform a fast 102. And they're even more of a nightmare to install in a 4th gen than a fast. Not to mention all the problems with the injector bosses and **** with the the msd.

Yeah, I'd imagine you'd pick up a lot more, lol.
I wouldn't run one stock, but a Mamofied MSD is DESTROYING, I'm talking like a barn-burner, Mamofied FAST. Yeah they need a bit of tweaking, but they perform. Moot point though. You couldn't pay me to run a cathedral head again.
Point I'm making is for ease of install and easy on the pocket, run a fast 92 with the larger injector of your choice, be it red tops or the 42# White Bosch 3's

Dude, if you're talking about what's in your sig.... your engine is bigger than even what's in my 2009 Z06

He didn't state what motor, or heads, would be used for the compare. I didn't ask either. Maybe he'll see this & chime in with some detail.

To the op, I think you'll be just fine with the 92. Could you see more power with the 102, yes. To me not enough to cover the install differences. I'm still happy with my 92 as well on my 383. I do want to "fix" it up a little.
Just a little history/info about the FAST manifold. The first Fast intake up to the 92 used the original design, which was by Wilson Manifolds. Hence the stamp on the intake. The 102 has a RHS stamp on it. I've always wondered if they just took the design by Wilson & put a bunch of little change/updates & called it their own? Or is it completely redesigned?
