Martin B has owned this 1991 300zx Twin Turbo Z for a very long time. With 237,000 miles on the clock he visited Z Car Garage for the first time in 2013. The difference between a general repair shop, an independent repair shop and a Z car expert is a big deal on a Z32 because it is a car that you can get behind on quickly. If you are not well-versed in this chassis you will throw parts at it endlessly, often leading to more repairs.

After more than two decades of working with Nissans, the crew at ZCG have got it down. The 90-96 Z32s are some of the raddest Japanese sports cars of the era. We know what to do and what not to do. For Martin’s first visit we corrected the knock sensor and harness, replaced the clutch with a JWT HD unit, turned the existing flywheel, replaced center support bearing, clutch M/C, power steering hoses and corrected rack bushings:

We installed a few suspension parts including new adjustable camber arms:

The transmission had several leaks needing attention:

After 237k miles the driver’s seat had seen better days so we rebuilt it from frame to padding and sent Martin on his way…

Later that year, after enjoying the car with the ZCG touches he felt that it earned a place in his collection. With 240k miles on clock,  we removed his engine/transmission for a rebuild using a Rebello VG30DETT with JE pistons, Eagle rod and balanced with ACL bearings. Full engine bay harness service as well. Many more pictures of the build in the gallery below!

All hoses and parts in the engine bay that are relatively inexpensive were replaced while the engine was out:

The drivetrain is installed and buttoned up. A clean Z32TT engine bay is a treat to look at, despite the complexity:

On the dyno the freshened engine made 318hp/320tq to the wheels:

It has been since 2013 and Martin’s Z now has 255k mile on the clock. We touched up everything and added some Work Emotion wheels (not pictured).

Enjoy The Ride, Martin!
