Performance part. Our Stage 2 turbocharger with intercooler is a complete bolt on system for the BMW "Big 6" six cylinder engine on E24/E23/E28/E34/E32 chassis. A medium pressure system (10-13 psi), it was designed to work on stock engines with standard compression (no special pistons needed). The Stage 2 system was designed to significantly boost performance, with a torque increase of 55-75% to be expected.
Kit includes cast iron exhaust manifold, TO4E turbo, Tial wastegate, 3" ceramic coated downpipe, 30 lb injectors, billet fuel pressure regulator, Bosch air bypass valve, K&N air filter, cold air intake pipe, custom computer chip, oil lines with fittings and all necessary silicone hoses, couplers, clamps and gaskets. Intercooler components included are a water to air intercooler, Bosch heavy duty recirculating pump and dual aluminum heat exchangers.
The only problem with this is that its $5,100 ~(not shipped) and in California.
Wonder what that goes like?
