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 .

    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
    • It's TWO steering wheels actually. 😛 one for each hand They are wheels, and they steer!
