When I was Building my Z31 I was having an issue with the stock S-Pipe slipping off the turbo and causing issues with letting un-metered air into the intake system and this was causing a rich running condition. The Stock S-Pipe is also one of the most restrictive areas of the Z31 Stock intake system. To do away with this I have made a Pass through solid motor mount that allows for the intake air to the turbo to pass through it as seen below.

Motor Mount Installed

The mount is made from a 1″x 3″ x 1/8″ Rectangle tube for the base, 4″ Sch 40 Pipe for the center pass through and then 1″x 1 1/2″ and 3/16″ Steel for the engine side of the mount.

In 1985 The 200ZR was Created and was the last of the Z cars to have a straight six engine. Nissan dropped the L-series motors and instead used the RB20DET motor in the 200ZR. The RB20DET is a Inline-6 2000cc Twin Cam Electronic fuel injected Inter-cooled Single Turbo and is the same motor used in the R31 Skyline GTS. It also had higher speed limiter, stiffer suspension, and a LSD R200.

The Dashboard was fitted with white face guages like the 87-89 300zx and different interior Fabrics.

Out side it had a small lip on the front air dam like the 300zx turbo models. It also had a Large hood scoop centered on the power bulge. This directed air into the top mount inter-cooler on the RB20DET. The 200ZR was offered with a set of 15″ Alloy wheels that were used on the 1986 300zx Non turbo.

The Differential offered in the 200ZR was a long nose R200 Limited slip unit with a 3.545 Gear set.

The 200ZR – I was offered again in 1987 – 1989 with the RB20DET motor just like the Zenki models.

The 200ZR -I also kept the Arched fenders like the Zenki models but added the new Kouki nose, headlights, Tail lamps and Bumper. It was Available in both 2 seat and 2+2 models. The 200ZR – I was only available in a Slick Top model with manual Transmission.

Differentials in Automatic transmission models received a 4.625 gear set and the manual models received a 4.375 Gear set.

The 200ZR – II was offered again with the RB20DET motor just like the Zenki models and the 200ZR – I.

The 200ZR – II also kept the Arched fenders like the Zenki models but added the new Kouki nose, headlights, Tail lamps and Bumper. It was Available in both 2 seat and 2+2 models. The 200ZR – I was only available in a T-Top model.
