This performance turbo kit provides the final touch cleaning up the smoke and enhancing the power for the E7 VMAC I & II engines that have been cranked between 475 to 550 hosepower. It provides faster acceleration, more air volume, and clears up the majority of smoke for those engines that are putting out serious horsepower. This kit includes a wastegated turbo, an elbow boot connecting the air filter ducting to the inlet of the turbo, an adapter clamping to the compressor housing outlet leading to the charge air cooler, and the appropriate clamps. Slight orientation of the turbo may be required for final installation, but in the majority of cases the turbo should be a direct fit. Call our parts department if you have any questions. 800-891-8038
