You will experience much quicker spool. Increases 10-20 horsepower and 10-20 ft/lbs tq. Perfect for everday use and also a major bonus for you autox'ers that need to keep the stock turbo but want more power. Watch that boost needle swiftly jump right up even at partial throttle.

Turbo exhaust side is thoroughly ported on the inlet and outlet.

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.
