The Car

The car is a 1993 Alpine Silver Lexus GS300(soon to be badged Toyota Aristo). I purchased in April of 2005, and 6 months later in the car was turbocharged. Due to a faulty radiator the engine blew a head gasket and the car sat for over 2 years. It has now been resurrected and will be my greatest build and achievment yet.

Intake Manifold
The intake is a custom made intake using 4" aluminum piping, and 1/4" aluminum sheet metal. Velocity stacks were manual spun out of 3" bar stock on a manual lathe, then flow tested within 2cfm. The stock NA manifold was cut short, and the aluminum plate was cut out with a hold
Intake with fuel rail
saw to fit each runner, then welded. Each velocity stack was then welded to the top of each runner. Using several specified pieces of 1/4" aluminum sheet, the manifold was assembled and welded together to form a nice tapered design to the thottle body plate. A Q45 flange was used for the larger 90mm Q45 throttle body.
