I'd agree with the other folks.....if you want to mod an engine, pick up an M20B25 from a junkyard and stroke it during a rebuild. You'll have a new'ish engine with appx 190 crank hp from a 2.7L stroker.
The funny thing about the M20B20 is the horrendous gas mileage for such small displacement.........I swear, but never measured, I get the same gas mileage out of my stroker compared to my M20B20
