Mitsubishi 4B11 HP engine kit N/A. The 4B11 N/A motor is one of the most overlooked performance platforms on the market, and the least understood as compared to the 4B11T(turbo) motor. Lets so lets start with the block it is Alm with semi open piston sleeves, The advantage is that the sleeves are only 2-1/4 deep , but are a huge. 410 thick for extra strength. This allows more HP to be made then would be expected, as others in the past had thinner cylinder walls.The cranks are STD Forged the preview to the Turbo engine. Though the caps are only 2 bolt they are billet for extra strength. It comes with upgrades ignition with Iridium spark plugs stock. Unlike the Turbo motor it has a longer rod which keeps the pistons higher in the cylinders so they reduce friction while increasing dwell time.
Crank pin(48mm) reduces friction. (Turbo 52mm) and a lighter piston and pin being 21mm N/A and 23mm Turbo making its ability superior for reving faster.
Along with smaller add ons like exhaust etc the potential is there for a real HP engine. 4 forged pistons 11-1 compression. Complete gasket set>High Lift Johnson.Pistons come in 86mm& 86.5mm 11-1or can be ordered in lower compression for Turbo application. We expect this engine will be able to use aprox10-12 LBS...
