Where do you start...

If you want the AWD system, I won't even bother mentioning everything, just get a GTR or a drop a RB26 into a GTS4.

A RB25DET or a NEO RB25DET is the better option. If you have your heart set on the RB26 (a whole +70cc of displacement over a RB25) in RWD and willing to screw around, then you will need the engine obviously (with the front diff cut off) and at least a RB25 gearbox or a RB26 gearbox (with transfer case cut off) as a RB20 box can't take the power, new fuel pump, new turbos.... I'm not even going to bother continuing.

I have a gts4 and nearly have the funds to do my 26 swap,for you tho it would be easier and cheaper to go the 25 in a gtst but if your hearts set on a 26 and you have the money and time for the hassles that go with the swap go for it mate..

I believe on paper a Neo RB25/S2 Stag 25 ? puts out 206 kw and an R32 26 on paper 209 . Neo 25 is probably a cheaper simpler better all round road engine with a lot less complications/agro . Stag 25 block is like a 26 round the sump and possily has a better ratio diff for the larger (than RB20) engine .

Your call , late Stag 25 better option IMO .

    • Is it alright to top up with just another green coolant?
    • thanks GTSboy. My confusion at the moment is i am trying to locate the ignition, ECU battery power and the ECU negative The closest thing i can find is the for the S15 on Page 8 of the Wiring Specialties web page https://drive.google.com/file/d/0B9F33_M_GgENQnZ6STMxVmVNd1E/view?resourcekey=0-eZ4nNRwRoqa1qvKlWWHm8A I cannot find the same diagram for the R33 RB25DET Series 2 dash plug pin out.... Do you know what the Pins? or know where i can find the same pinout diagram for the RB dash plug? Thanks for the advice on the box... i like a 6 speed so might be on the lookout or the box now.. a topic of discussion for another post...
    • Will have a look at that. I cant see any leaks 
    • Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.
    • Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
