Compressor side inlet and outlet are ported and tapered out.

Porting and Polishing of the stock turbo is very advantageous because:

  • Keeps the external stock look(good for emission reasons)
  • Faster turbo spool by 200-600 rpm
  • Increased gas mileage
  • Increased horsepower and torque(10-20/hp and 10-20 ft/lbs tq)

Ceramic coating of the turbo is important because:

  • Greatly decreases engine bay temperatures
  • Turbo will retain heat more which increases exhaust gas velocity.
  • Higher resale value because the coating will protect the turbo from corrosion


NOTE: This service requires you to send in your turbo for port and polish work. We are unable to provide core exchange on this item. Porting services may take 4 to 6 weeks to complete, so call our customer service staff for a current lead time.

COATING: Because porting is done to order, adding coating services to your order will increase it's lead time because coating is done in batches. Please allow up to two weeks for coating services.
