Garrett GT2860R (GT28RS) 350hp "Disco Potato" ball bearing turbo with S15 comp cover

We have made a limited number of special order "Disco Potato" GT28RS turbos with the S15 style comp cover that is flange style bolt up rather than hose clamp style normally used.

The Potato turbo great bolt-in replacement for the Silvia's stock T25. In fact, from the outside, the two turbos look nearly identical. The oil feed and both water fittings for the water-cooled centre housings are identical to the stock turbo. They do require minor modifications depending on make and model as they are a generic turbo not model specific (mainly the comp cover and actuator positioning and plumbing).

It was developed by Garrett in the US for a project car called the Disco Potato with an SR20 powerplant.The car's power was impressive, 280 hp at the wheels, but not earth-shattering. The driving experience however, was. Throttle response was excellent, turbo lag virtually non-existent, and the tyre-smoking horsepower was outstanding. The turbo spooled up early, making so much torque, that the best quarter-mile time (13.7 at 104.5 mph) was achieved launching in second gear. The vehicle was so successful that Garrett the turbo as the GT28RS.

When ordering please let us know which housing size you want: .86, .84 or another size.
