has anyone attempted to port the stock beta 2.0L manifold?

i was curious as to what results have been acheived...

i was thinking of opening up the collectors at least...

get a little bit more flow capacity when using nitrous... i think the engine will thank me with a nice boost in power smile.gif

 

In theory, you could probably get some minor gains. But since headers provide such a large gain, most go with headers.

 

what manifold are you reffering to?

 

the exhaust manifold.
