good choice for you I think

use the rb26 ecu and loom afms etc .

you gear box will bolt up hicas and abs are separate to the motor..

you will also need a different sump for the rb 26 as that one has a diff in it your rb 25 sump could work but might need a few mods

u will need to modify and splice the 2 looms together. as for the rb25 keep it aside , as u will need bit and pieces of it to make your rb26 works. also the power steering pumps need to be modify as the rb26 is a dual lines unit and a rb25 is a single feed item, hopes that help abit. but do it, it brings smiles on your faces every drive.

Four more questions :(:

1. what is sump

2. what does loom mean?

3. Will GTR ceramic clutch fit my (rb25) gear box?

4. I heard that 280 hp is a law limit in Japan. But the real potential of rb26 engine is much higher, so how do i use the potential - just get a reprogrammed ECU?

about the power steering pump - i was planning to fit my pump to that rb26 engine, i guess it will work fine?

rb26dett sump has the front diff moulded to it so u cant use in your car but u r rb25 sump should fit on the rb 26 block thats what meggala was all about other option would be to modify the rb26 sump cut the diff off and a bit of welding .

yes you will be able to you will just need to have some one doit who can trace the wires back . the speedo runs off a cable to the gear box you will need to find the source for the tacho. one trick is to keep you alternator and starter wiring from the rb 25 .

I think your water temp should be ok as well oil pressure should be the same or very similar.

I fitted an sr 20 into my r32 most things in my dash do work only the tacho isnt working but we will sort that

The tach is simple, just find the wire for the tach on the cluster, should be yellow/red, then find the wire on the ECU pin out, and splice a wire from the ECU tach signal wire to the wire in the back of the cluster. Thats how I got the tach to work in my RB20 240sx, but I had to put the R32 tach into my 240sx cluster, meggala, you may need a different tach, I know the SR20 has a different signal than the RB20 tach signal has. It reads 2x as high with the tach meant for my KA.

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
