Vtwin engine with reduction drive and wiring harness: $7,250 1 1 would be 134 HP. , All of these AC Corporation diesels use a two-stroke engine cycle, but Andy says he has a way of stratifying the exhaust charge inside the combustion chamber resulting in many benefits. Because the Fit engine has its exhaust manifold integral with the cylinder head, the engine is not a good candidate for turbocharging, but it does boast gasoline direct fuel injection (fuel is shot directly into the cylinders). Theres little wonder a factory re-man is considered new; not much more than the engine case, crankshaft, connecting rods, pushrods, rocker arms, some drive gears, and maybe some of the tin work (valve covers, pushrod tubes) is re-used. Andy has been showing a series of interesting compression ignition engines on his website, without question the flashiest one being the E-1000 V-12 which carries a cool 1000 to 1600 hp rating.
