Garrett GT2860RS (Disco-Potato) Dual Ball-Bearing Turbocharger Kit for L-Series

Garrett GT2860RS (Disco-Potato) Dual Ball-Bearing Turbocharger Kit for L-Series

from $1,405.95

Looking for a good replacement for your OEM T3 turbocharger? This turbo offers the same quick-spool characteristics of the factory T3 turbocharger, but with modern technology. Featuring dual ball-bearings, a GT28 compressor housing, and a 1 BAR (14.5psi) wastegate actuator!

This is the perfect option for someone wanting more power from a turbocharger upgrade, but wanting to maintain the factory spool characteristics and response. This is a common upgrade for the Z32 Twin-Turbo crowd, and we have found to be a very good mild upgrade for the L28 engine. The max boost pressure recommended for this turbo is around 24psi, and is commonly dubbed the “Disco-Potato” upgrade in many circles.

This kit will require some minor fitting, as the flange is a T25. The following areas will need to be addressed for fitment

  • Turbo studs removed from factory manifold, and included T25 to T3 adapter installed

  • Compressor housing clocked for proper orientation, and wastegate actuator removed and bolted to different part of compressor housing

  • New intake and charge pipe worked up

  • New downpipe made (we include a 5-bolt to 3” v band adapter)

  • -10an Return bung welded to factory oil pan

If you are not in the position to do any of the fabrication work listed above, we offer this as a complete exchange service, please e-mail us at Godzillaraceworks@gmail.com to discuss specifics.

Available add-ons include the oil supply hose kit, return hose kit w/ fittings, and coolant fittings.
