forget boost unless you sleeve the b20, b20 cylinder walls are really thin. I did have a b20 in my hatch, the torque line was awsome, went straight to 130ft/ibs at 2k and held all the way across the rpms. have dyno sheet to prove. just had a fp guage and bumped up fp. b20's will run 14.0's in stripped hatches all day with minr bolt ons
