FYI (actually for most other people here since you probably know that)- 20HP gains with standard port/polish techniques is not unheard of on the B18C engines when mated to proper exhaust manifolds and exhausts. I don't know what it's worth on a F20C. I'd wait for a stroker kit!

I am betting there is not going to be anything near 20 HP on the S2000 engine. To produce 120 HP per liter the engine HAS to be flowing alot of air. There just won't be much more to be gained. The B18 engine left much more to be gained than the S2000 engine. I would say less than half of that. Is 5 to 10 HP (max) worth the expense and effort (as well as losing your warranty)?
