easier method of adding a turbo
charger to popular LS engines.
More durable than traditional ex-
haust headers, manifolds are sold
per pair, complete with V-band clamps and flanges, heater hose heat shield, and header bolts. Available cross-over tubes are constructed from mandrel-bent 304 stainless steel com- plete with a flex joint and welded V-band flanges. Compo- nents are fully compatible with most common LS swap parts.
Custom engine mount brackets allow installation of a late model Coyote engine into an 1984-95 Ford Mustang using the stock K-member. Powder coated for corrosion resistance, brackets are sold per pair complete with hardware.
