Rb26 Conversion Tutorial - How To Do It!

[STA63A]

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.

No problem... good luck with your swap.

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....................

Hi was just wondering if you has wiring sorted as i am doing rb26 con on my s1 rs4 already done manual bit so just lump to go in any help will be great regards mark.....

Never done it but should think if you got the loom and ecu with the 26 you are 99% there - just have to work out the connection with the atessa.

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.

OK. What about the gearbox sencers that's on the box do thay not need to be rewired to plug into the stagea loom.
