Options | Installation

The CJ Motorsports HR / VHR Oil Rail is a product of our twin turbo system development for the RWD Nissan HR and VHR engines. The oil rail kit plumbs itself in-between the engine and the factory oil pressure switch and provides a pair of -4 AN oil pressure outlets for sending oil to the turbochargers.

A 1/8 BSPT to 4AN adapter is provided to thread into the engine in place of the oil pressure switch. The opposite end of the oil rail is threaded 1/8 BSPT to accept the original pressure switch. The rail inlet is threaded 1/8 NPT and so are the bottom outlets. 1/8 NPT adapters are provided for each of these 3 ports.

The rail secures to existing M6 threaded bosses on the front of the upper oil pan with included stainless hardware. A short length of wire, butt splices, and heat shrink are included for extending the pressure switch connector wire to the new location. Cushion clamps are supplied for routing the oil hidden behind the oil rail.
