300zx Z32 Turbos Direct Turbo Kit w/ New Garrett OEM CHRA, Standard Cast or Billet Aluminum Compressor Wheel - Twin Turbo TT 90-96 - Manual Transmission, Standard Compressor Wheel

This is a great alternative to buying brand new turbos outright, as the only part that typically goes bad (the CHRA) is replaced with a new unit, while the housings are re-used to keep costs down.

Compressor Wheel: Turbos Direct offers billet compressor wheels for stock turbos. These retain the same diameter of the stock wheel, but the billet construction allows for a thinner root of wheel. This, along with changes to the overall shape of the blades, allows for greater blade surface area while slightly lightening the compressor wheel, so spool response is the same, if not faster, than stock, while providing a 10-15% increase in output.

Automatic vs Manual Factory turbos differ slightly between AT and MT vehicles. AT vehicles had a .54 AR on the exhaust housing, and MT had a .63 AR. This means the AT's exhaust (turbine) housing is slightly smaller in diameter, and produces less power, but spools slightly faster. Please note: this is the AR number cast into the turbine (hot) side, near the 4-bolt rectangular flange where the turbo meets the manifold. The ".48 A/R" cast into the compressor housing is not relevant.

Warranty Disclaimer
These are brand new, genuine units direct from our authorized Garrett distributor and builder. They are not rebuilds or substituted with any other brand.
Garrett's warranty is a 90-day period against manufacturing defects, and accepted on a "per inspection basis." It is extremely rare for new CHRAs or turbos to be faulty or defective from the factory. If failure is suspected, they will need to be sent in at the customer's expense, and they will be torn down and inspected by Turbos Direct. Garrett's warranty does not cover shipping charges in either direction.
If following a fresh engine rebuild, which includes new turbos, smoky or oily exhaust is almost always a result of a bad rebuild and not faulty turbochargers.
Installation errors, abuse, mishandling, or failure from external factors (foreign object damage, oil-fuel contamination, oil starvation, overheating, etc) are not manufacturing defects. Nearly all premature failures are caused by an external factors such as these, and are not covered under warranty.
In the event that you experience a failure, and the cause is determined not to be a manufacturing defect, you will be responsible for re-assembly and return shipping.
