Z1's VGX800B Ball Bearing Turbochargers are the latest iteration of Z1's VGX turbo kits for the 1990+ 300ZX.. They are virtually identical to the original VGX800 Turbochargers, but use ball-bearing CHRA's to improve spool time and response. They offer more performance potential than any other product in our catalog, supporting up to 800hp with the correct supporting modifications.
VGX800B's are a 5-bolt, ball-bearing turbo sporting a .60 A/R compressor housing and billet compressor wheel. They feature a custom anti-surge compressor cover and come pre-clocked, making them a 100% bolt-on turbo with no necessary modifications to the turbo or the car. The kit includes all installation components necessary, including oil lines, gaskets, hardware, and silicone hoses.
VGX800B Features and enhancements:
- Highest level of performance potential of any Z1 turbo kit
- Ball Bearing CHRA
- Utilizes 5-bolt downpipe
- Advanced turbine blade design
- Next-generation billet compressor wheel
- VSR-balanced rotating assembly
- Custom compressor housing makes it completely bolt-on
- Anti-surge turbo inlet
- 48 lb/min flow rating
- Provisions for turbo speed sensor
- Compressor A/R .60 Turbine AR .64
- Includes oil lines, gaskets, and hardware
- Adjustable HD wastegate actuators (1.0 or 1.5 Bar)
These use brand-new compressor and turbine housings, designed specifically to house the larger compressor and turbine wheels. Inside the compressor housing, you'll find a lightweight billet compressor wheel, helping contribute to their excellent response. We have also employed a ball bearing CHRA assembly to further improve the longevity and response of these turbochargers. The inclusion of a .64 A/R turbine housing provides exceptional response without becoming a restriction at higher power levels. It also maintains great spool characteristics in mild street-driven applications.
The first dyno graph below highlights the efficiency of these turbos, producing 553whp and 535wtq at only 20PSI of boost!
The second dyno graph below was captured on a 300ZX sporting a set of Z1's VGX800B Turbochargers, the 3'' Catback Touring Exhaust, and all of the necessary fueling and induction modifications. It produced an astounding 689whp and 607wtq on 104-octane race fuel and the stock rotating assembly, only held back by the fuel system and the owner's wallet.

Installation Note: As is the case with any turbo larger than stock, slight trimming of the motor mounts and clocking of the turbo may be necessary if using aftermarket exhaust manifolds. This is dependent on the installer and the use of other aftermarket parts. It is also possible that your downpipes made need clearancing to fit the large wastegate.
