Default FAST 90mm Top Shell Only?

Is it possible to get this from anyone? I called one place and they said they did not have it for sale anymore. I have 78mm FAST intake manifold and would like to upgrade soon. Thanks! Also, if so, how much?

Does anyone know? Is the 92mm shell interchangeable with the original 78mm manifold? Thanks.

I contacted FAST about this and they never responded. I and pretty sure they will interchange, I believe the 92 is just an updated version of the 90, but bot 100% on this. I am in the same boat as you.

i am also looking to do the same upgrade from the 78 to the 92 and was wondering if it would interchange and if you can even buy just the top section?

The WS6 store has the 90mm shell, does anyone know if anyone sells the 92mm shell? And keep us posted bandit-00.

I still haven't got a reply from FAST, somethings they reply on some they wont. Now the 92mm is discontinued as well with the only new choice being the 102mm. I'll contact Wilson manifolds and see what they say, I have been dealing with them on throttleblades lately and they seem to be pretty helpful.

FAST wont tell you it will fit most likely. That blows their sales up when people sell the 78mm and buy a 92mm. That top shell is just half of what they would make.

straight from FAST:

No parts interchange between the 78 and 92. The old 90 and 78 shared most
parts, though. We do not make the 78 anymore since the 92 came out.f

Thanks,
Matt@FAST

The 92 top shell WILL interchange, however you cant get any 92mm parts anymore. The 92mm is done and gone. Only dealers who have parts still in stock is the ONLY place to get them.

I was on the phone for a while with fast, i forgot who this was 2 summer ago. But he had to find a older 78/90 parts, but found them, And the newer 92mm style, did not fit. The lower and mid section are mold style rev.J and diffrent.

they sold all the parts they had, do this online only speed shop. I forgot there into it comes up in google. It was some 1-800 place. Like the 1-800- headers, type parts ***** place.
But they sold there parts out a few years ago.
