Are the stock intake manifolds on b20's to big to fit in an EF? Is this true for both the b20b and the b20z, or just one or the other? I think I read somwhere that you have to use a b18 manifold or get an aftermarket manifold from skunk2 in order to get hood clearance. True or false?

 

even if it does fit, you don't wanna use it... you can pick up a LS integra manifold cheap that will fit, make more power, and be better for modding in the future (not being from what is essentially a truck motor)

buy an integra manifold and call it a day

 

Me says no! I dont think it will work because there is limited clearance to begin with. Go with the LS mani.

 

LS mani..any particular year?

 

They are all pretty much the same... the later ones are a little cleaner looking (they don't say PGMFI on the top)
