I have one pair of brand new custom hybrid turbochargers for sale, ready to ship - $2350 plus shipping. These are the Garrett GT2860RS "Disco Potatoes", but with several mods and a couple of variations in the design which produce significantly improved spoolup, broader powerband, and are capable of producing the full ~31psi of boost pressure that the Garrett 60mm 62-trim compressor wheel is capable of. These are not your typical shelf-stock GT2860RS, to say the least, and it has been quite the challenge to work Garrett to produce these for AshSPEC. In addition, there are a multitude of additional improvements I apply to these turbos in-house.
Specs:
- Standard T25 mounting flange with 4-bolt .63 A/R turbine housing.
- Wastegate Port Increased to 25mm (from 20mm)
- Housings have been port matched and casting flash cleaned up with special attention to cleaning up casting flash at the turbine housing nozzle as well as increasing nozzle impingement angle for improved spoolup.
- T28 Bearing Housing w/wider T3 journal bearings for greater longevity.
- 360-Degree thrust bearing group for significantly improved longevity and improved shaft dynamics.
- Carbon Race Shaft Seals for Improved Longevity and Leak Resistance.
- Custom machined compressor housing inlet flange desgined to more efficiently deliver incoming air to the compressor wheel.
- Wastegate control arms have been re-positioned to achieve proper actuator rod to wastegate arm angle.
- Garrett high-tension single port wastegate actuators
The turbine housings have been ported at the inlet flange to match the OE gasket and the internal casting "roughness" has been removed to produce the best possible flow. Great attention to the turbine housing nozzle has been paid as casting finish in this area will have significantly more negative effect than a smoothed nozzle. The nozzle area has been cleaned up and the nozzle impingement angle has been increased a few degrees to further improve spoolup response.
