Will a Fd exhaust manifold fit of a 91 Engine?? My buddy wants a T4 exhaust manifold for his 91 but i cant seem to find any. All i can find is for the FD so im just wondering if i get him a FD manifold will it fit? I used to see them on ebay for the FC all the time, now i cant find even one. Any suggestions?

 

What im really not sure about is the manifold studs. I dont want to order him one and it doesnt fit right.

 

the studs are not a problem all 13b flanges are the same.

 

Some FD manifolds will fit the FC, some require using an on-center turbine housing( which is bad). If the main engine flange is less than 1/2" thick the fd studs will require washers on the nuts.

 

The cheapie Ebay manifolds don't properly fit a TurboII - test fit one a long time back. Not to mention they are ultra crapola, and you'll be fightings cracks something fierce.

Can he get the HKS T04 manifold for the FC? It's like $250 or something brand new, heavy cast iron, and guys have made crazy power on them. No sense reinventing the wheel there.
