These turbos come with Brand new CHRAs(Center Housing & Rotating Assembly)and reuse the original JWT Sport 500 housings. The Garrett CHRA is brand new and not rebuilt, thus you will essentially be getting a brand new turbo, and not a rebuild.

Garrett is the manufacturer for the original oem turbos for the 300ZX. After so many years, turbo charges start to wear and lose potential horsepower. Turbos will start to leak, due to aging seals and/or worn bearings. It is highly recommended that turbos are replaced with brand new Nissan replacement CHRAs(unless upgrading).

Turbos must be shipped in 1st, we do not have any cores to build at this time. You must return original JWT Sport 500 Turbos, we will not accept Stock or any other Turbos for cores.

Please send the Turbos to:
