Hi all after a buggered rb25/20 turbo as I want to learn more about turbos and wondered if anyone has a dead one they want to donate or sell really cheap. I am not after one to repair just want to pull it apart an figure out how it works etc. located in melbourne prefered.

Thanks

Ashley

Don't have anything for sale, but happy reading here:

Here's also a starter on the differences between RB20 and 25:

It is worthwhile getting your hands on one just to check it over, and the two things I've learned is

1. biggest is not always best

2. more (impeller blades) can be better

If you have a technical bent, then it is a fascinating area of study in engineering. People talk about this trim, or that A/R, or that major diameter, sometimes without realising that it is a difference of less than 6mm and yet it can make a difference of 100hp and seconds of lag.

cheers

when you pull them apart, there's literally nothing to see at all.

you've just got the wheels, oil section, water section. Very primative sort of thing.

you'd be better off researching about turbo technology e.g. different wheels, shafts, bearings etc on google.

hi guys

thanks for the reply

that garret site has heaps of great info.

I am a bit of a handy man when it comes to my car and like to pull things apart to get a good understanding of how they work and how hard things are to rebuild etc.

Hehehe sounds like me, just like ripping shit apart to see whats inside for yourself :D Sometimes I can read something a million times and it still wont stick or make sense til I just bust one open and take a looksie.

I did the same thing about a year ago, bought a shitty rb20 turbo with blown seals, got seal kit from nissan for Im pretty sure it was 170 bucks, and put a seal kit through it. Had a look at how everything worked on the inside. Was really good, I knew how they worked prior and understood the theory but nothin like gettin your hands dirty n rippin stuff apart to really get a good grasp of how everything is put together :)

i have a dead rb25 turbz if ur interested

Sometimes I can read something a million times and it still wont stick or make sense til I just bust one open and take a looksie.

by far THE quickest way to learn anything,...

thats how i started off, now repair turbochargers for all vehicles all over the uk

if there is anything i can help with drop an mail, and ill try my best : )

    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • 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.
