Timeattack 20b turbo porting!
So..... i just bought a 20b (c240 with black raised letters on the housings whatever that means)
and im gonna get it pinned/ported/balanced/clearenced/oil and water mods.
So i started thinking about the porting, my goal is a 500-600rwhp on e85 (gt4088r maybe)with durability and a broad powerband and a very responsive engine.
My builder suggest a early primary port opening and some exhaust porting with only a minor cleanup in the secondaries.
What do you guys think?
