73Ed Posted Friday at 07:26 PM Share Posted Friday at 07:26 PM (edited) I have a 73 240z with an RB26, ECUMaster Black ECU and SpeedHut Guages for Oil Pressure, Oil temperature. The ECU needs oil pressure and temperature as well, so I have 2 of each sensors. I am running the mishimimoto thermostatic oil sandwich plate/cooler which only has 1 1/8"NPT port. How or where can I install all these sensors? Does anyone know what this port is for, between cylinder 4 and 5 on the intake side of the 50U block?

240Z Turbo Posted Saturday at 06:19 PM Share Posted Saturday at 06:19 PM I have an RB26 260z running EMU Black and PMU-16.
