306 S16 Outlet Manifold On Rfv-engine

[sub205 5]

Hello,

 

is it possible to mount an 306 s16 outlet manifold to an RFV-head ? (oval ports)

 

are the bolt positions the same?

do the ports match?

Do you mean a gti6 manifold? an s16 manifold is cast and not going to be any better than the standard rfv one. Im pretty sure an s16 manifold wont fit anyway.

the service-box pictures tell another story, but i want to hear it from someone who tried it :-)

 

what have you done to your engine to get this power output?

i'm currently in the process of an rfv-rebuild and will rework the engine where it is useful.

better cams, optimized/planned head, etc.

i think the 150ps s16-inlet-manifold is optimal for a good compromise of torque at lower rpms and power at higher rpms.

i want an engine that revs good till, lets say, 7400rpm.

S16 manifold isn't very good. It's too short and tends to crack. If you want to optimize your exhaust buy proper 4-2-1 manifold. By proper I mean one that is designed based on your engine specs. Changing exhaust cam means that tune of your exhaust manifold changes too.

But anyways long story short, the GTI-6 manifold is better than S16 in every possible way.
