I used the Stagea pump, bracket (I slotted the rear-most mount bolt to make it easier to install with the twin turbos), and crank pulley. Seemed like the easiest solution and has worked for just at a year now without problems.

Ah ha you put the RB25 crank pulley on th RB26 to line up, that makes sense, thanks.

I am currently doing an RB26dett manual transplant to my previously RB25det s1 auto Stagea, here's a few pics, let me know if you need any more pics (R33 handbrake mounting, R34 clutch pedal & master install etc.) and I'll try and post them as it's still in the process of conversion........

Have you started to work out the wiring side of things yet?

I am starting to think this is a better way to go than keeping the Rb25. Have been looking into this conversion a bit more lately.

Did you lift the motor and box in from below or did you feed it in from the top?

I have the various Stagea / GTR wiring diagrams and have been scribbling notes on them as to which wires need to go where, but have not as yet started to physically cut wires and unwrap looms. I am still doing the final mechanicals, currently sorting out a rear GTR 4.11 LSD and driveshaft conversion to match the new GTR front ratios and upgrade to LSD rear.

I should get to start the wiring in the next few weeks so I'll post up progress and pics as I go. I would also like to hook up the GTR's front torque split gauge but haven't had a look at the wiring for that yet, and I have a torque split controller to wire in at the same time.

If anyone out there has any RS260 wiring diagrams please post them up! (I will swap you some hen's teeth! lol)

I pulled the motor and box out from the top and the same to put the 26 & manual in............see pics....................

has anyone got wiring diagrams for the rb26 engine loom to ecu and to what wires in the s1 stagea needs to be redone to get the rb26 to work with

and the wiring of the plug for the auto to manuel gearbox

thanks

I would think you need the RB26 loom and ecu. For the auto wires look in the DIY section above in the manual conversion thread.

Yes I do know I need a rb26 engine to ecu loom as I have that it's the wiring of that loom to the stagea std loom I need a diagram of.

And as for the auto wires I've had a look in the manual conversion thread and can't find the relevant post

Go back to the front of car with the four plugs. The two pin grey plug is your inhibitor switch, put a loop between those (cut plug off auto trans loom). The brown plug is for the reverse lights (well two pins of it anyway), hook those up.

      I'll probably be putting the shit box back on the dyno again soon, I want to dial in the closed loop boost control properly. I'll have a camera facing the car/motor for fun too. Just note, there are essentially 3x 10AN inlets going into the catch can and 1x going back to the intake pipe. Most of the time the catch can "return" to the sump actually is the crank case breather, pushing air out.

      I have the R3C with a Nismo slave and by no means does it behave like a stocker, it ain’t THAT bad. On take off just give a bit more throttle than you would say a coppermix and it’s fine. It will not slip though.

      Yet another RB Neo misfiring thread after reading all the others.

      Okay. Final round of testing done. Got a friend to hook up a fancy scanner to the car and we also ran some compression and leakdown tests, she is healthy.  The MAF was definitely the culprit. So for future reference anyone with similar issues that find this thread. I suggest the following steps, in order of affordability:   Check your spark plugs for any fouling, replace plugs if they are bad or re adjust the gaps making it narrower (0.8mm would be good). Check every coil's resistance with a multimeter. It can be done by probing the IB and G pins on the coil pack. Resistance should be around 1.4 (+/- 0.1) Ohms Check the MAF. If you have Nissan connect or a good scanner with the 14 adapter it should allow you to see the voltage on the MAF reading should be around 1.1 - 1.2V when car is idling. But if you don't, buy a new MAF from Amazon and test, then return it. (For instance, I got a Chinese one for $40 that was reporting 1.3v on idle). If you still have scanner, you can run tests on the injectors to see if they are working, just remember to unplug the fuel pump fuse/relay and have no pressure on the line. Then listen for the noises that the injectors make. Clean/replace injectors as needed. Once you find the issue and fix, order thousands of dollars worth of OEM parts to refresh unrelated things (Optional)   PS: Thanks to the absolute legends of this forum for the responses and help to someone that went a bit over their head.

      Ha ha ha, so they stopped the bearings spinning on the one you want, but then decided the crank hub should slip instead 😛   Stick to RB, at least you can work on it yourself. And now it doesn't smell of vapour   Also I still believe there's a chance your new flap doesn't "pop", as even though the engine might breath hard, it has a direct path with no restriction to the inlet, which when on boost should pull a bit of suction for you. If you do get pressure in the catch can id be very intrigued. Time to put a boost gauge on it, and a session at the track, then solid cover your vent and do another session
