Squeezing 800 horsepower from a four-cylinder ain’t easy. This 4G63 is put together with Arias 9:1 pistons and Howards Pro I-Beam connecting rods. On top is a Fox Lake cylinder head with Kelford 280s camshafts (Fidanza adjustable cam gears), along with Kiggly valve springs and lash adjusters.
An FRH intake manifold and Q45 throttle body help feed the engine with air forced in by a BW S363 SXE turbocharger. A DV/DT T4 divided exhaust header wicks the spent gases away and Tial wastegates (38-millimeter) and blowoff valve (50-millimeter) help manage boost.
Power is managed with a Vipec EVO 9 ECM custom tuned by John Whalen @ Whalen Speed Research and Development (WSRD). A custom Milspec Industries wiring harness helps hold everything together.
Fuel flows from an APM fuel cell via an Aeromotive fuel pump and a Kenne Bell 40-amp boost-a-pump. Bosch 1600cc fuel injectors handle the heavy volume at the cylinders.
As a car that was never sold in the states, this import is making quite a first impression.
