Hey guys i looked around and cant find much info on this topic, so I apologize for any repeat of discussion.

I was wondering if the 6 port gslse lower to upper mounting bolts were the same as the 86 to 88 fc.

I want to use the racing beat weber upper intake manifold on my fc lower, when i compare a picture of the gslse gasket to the fc gasket i have, they look just about the same. yes i know the website says 84-85, but i know sometimes theres wierd grey areas. Any info is helpful thank you

here are some pictures and links of my situation

i was going to say no its different, and i think it is, but really how different?

 

All i really need know is if the bolts and holes match up decently enough to mount it so i can run a weber dcoe.

 

Ive decided to go ahead and buy a gslse intake gasket, i will get back to yall if it works, feel free to add any input

 

If it doesn't work let me know and I think I might be able to help you out.
I don't normally hang out here so @ me or something.

 

I don't believe so, here are the gasket photos from Mazdatrix:
S4:


GSL-SE:

 

those are the plenum to the upper runner thing,




i do know the S4 to S5 the rear most stud is different, so we'd just pull it out and run without it, 4/5 would be an easy A when i was in school

 

Yeah heres the gslse gasket from atkins rotary on my s4 manifold. I did end up finding someone on Reddit by some miracle that had one of the discontinued racing beat weber manifolds for 6 port fc.
