Does anyone have an ECU pinout diagram for the R31 RB20det red top ECCS computer. Is it like the older NICS or newer R32 ECCS? Any help would be appreciated. Thanks, Geoff.

Keep your VVT. Simply tee into an oil feel (at your pressure sensor will work) and run a line up to the head. If you look back through this thread and at the page Joel has been compiling you will see where on the head to run it to.

Strutto, Your car has 2 knock sensors. They're screwed into the side of your block high on the intake side of your engine. All imported RB engines have them.

Is it available for R31s. Currently using SAFC & ITC. Emanage sounds great.

Great thread guys, I have been reading your posts for some time and finally thought that I should add something. My first point relates to the differences between series one and two blocks. Some series one blocks have all the necessary oil and water provisions ready for use and do not require any drilling. The major difference between the two blocks is on the front of the engine. The series two blocks have a machined flat surface with a hole drilled and tapped in the middle of it that you can locate your idler pulley on. The series one blocks do not have this flat surface and require a little fabrication to locate the pulley there.( Anyone who has issue 21 of Zoom magazine with the green Torana on the cover will be able to see that the RB30DE engine featured has had metal putty used to create a surface to mount the pulley). I discovered this the hard way almost 3 years ago. Secondly, using RB25DE pistons gives a very high CR(10.5:1) not a low one. Series 8 RX7 injectors are side feed and will fit the RB25DET fuel rail. Due to the rotary's use of primary and secondary injectors they come in 2 sizes. It has been a while since I looked at injectors so I can't remember the exact sizes but both are quite large and work better than the earlier 550cc top feed items. You have stated that RB20 fuel rails will fit R33 intakes. Only the ECCS rails can be modified to fit. The NICS rail is completely different. The bracket for your power steering pump & aircon comp will also need slight modification to fit due to one mounting hole on the block sticking out about an inch. Measure the difference accurately and simply cut the bracket down to suit. I hope this little bit of info helps someone. Be wary of R31s..........
