Z31 Pass Through Motor Mount

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.

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.

These Mounts are something I have been thinking about producing but need to get a feel for the need for them. If you are interested in purchasing one of these mounts you can message me at joseph@melnicksautoworks.com

200 ZR


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.
