Right i have stored at my mates pad a janspeed 4-2-1 manifold.
anyone got one and whats the power gains and stuff like on a 2.0 8v engine?
also whats the benifits of a crank case breather?
i know it helps let out contaminated air or something but i need a lil more info on that.
cheers!

You normally see about 3/4% with a manifold change, depending on how bad the original design was.
The benefits of those little breathers are that they look pretty.
