Intake Manifold queston
Sup everyone, i am new so don't flame me please, and if you do be gentile. I was wondering if any one knows a few things. First is; who, if anyone, makes an aftermarket intake manifold for the s5 turbo motor and is it worth it. Second; are the front, intermediate, and rear housings for the 20b cosmo interchangeable with the 13b. I looked but didn't really see anything so educate me please. thanks

Most people who ditch the stock intake manifold go for a IDA-style manifold and twin TB, and put a custom plenum on top. The only complete aftermarket intake manifold I've seen for 13BT's was made in Australia, was very expensive and IIRC added only 30hp to a 500hp engine. In short, not really worth it. You can't make far more power than is sensible on the stock manifold.

I got a question about intake manifolds too, but no one seems to know the answer. If I throw some block-off plates on my lower intake manifold for the valves, what do I do to the vacuum lines that normally ran to that location? DO I just plug them shut?
