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

meggala

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

meggala

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.

Thanks a lot! i will be doing all this stuff myself :) will spend whole winter to prepare my car for the next summer season. i guess you don't have snow in winters? :)

we dont have snow... just rain, that makes for good, WIDE, drifto at the saving of tyres!

But yeah, if you can do it yourself good luck, post up pics too.

I love seeing 26's.

There is a 26 going into and R31 here in melb ATM. It's been done before but it's still cool!

    • @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand
    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
