how can you tell if you have a 90mm or 92 mm fast intake?

just measure the opening? or is there a part # cast into it?

and where can you get replacement gaskets for these models?

thanks!

 

the 92mm says 92mm the top by the FAST logo

most of the vendors carry the replacement gaskets, either pm them, or check ws6store or texas-speed

 

We carry them on hand as well. FYI the Fast intakes 78/90/92 for cathedral port will take the same gasket. 27.95 for the set.

 

So technicaly i might have a fast 78 or fast 90 then since its doesn't say anything other than FAST and Wilson on the top of the intake?
there is no numbers onit!

 

yep, measure it, or compare it to your stock tb. You should be able to tell if it is 78mm or 90mm. Also, the FAST 90's opening is round, where the FAST 78's is like the LS6, round with another section out of the top right, here is a pic of the FAST 78

 

thanks man thats what i needed to know

and I am wanting to replace not the gasket where it meets the heads but the
gasket where the two halve come together since I am gonna have it apart are all those the same or different on different models?

 

lucky for you, I'm extremely bored. here you go, its called "F.A.S.T. LSX Intake Manifold Top Shell to Inner Shell Replacement Gasket"

thanks man!

 

From the last I remember of seeing them....The FAST 78 is a 3 bolt TB opening. The 90/92 were 3or4 bolt....that is an easy way to tell.

 

fast 78 mm 3 bolt,fast 90/92/102 4 bolt tb.
