Each kit includes the complete turbocharger with compressor inlet pipe, compressor outlet hose, t-bolt clamps, gaskets, o-rings, exhaust ring, exhaust v-band, exhaust manifold gasket, new studs, bolts, and washers, all new oil and coolant line o-rings, and our ECU Upgrades for select vehicles. The upgrade uses your factory electronic wastegate and diverter valve, and connects to your factory exhaust, intake, turbo outlet pipe, and oil and coolant lines. This system has seen many road course track days and extensive testing to ensure longevity and reliability of the setup in the harshest of conditions. This setup does not spike torque hard or run on the edge of what the factory rods and pistons have been known to handle, making it as safe on the stock engine as we can for these power levels. Go APR!
