Hey All

I bought another spare turbo for my R33 Gts25t but have discovered some differences. Can anyone help me in telling me what it is off? Main differences:

Spare one I bought is only oil cooled and does not have water feeds.

On Turbine side there seems to be more blades and the turbine hole is bigger

Compressor blade looks very different to.

Pictures are below.

it is water cooled

post-a313519-Standy-Side.jpg

looks like an r33 turbo to me. and this looks like the coolant feed.

both the compressor and the exhaust housings point towards an r33 turbo

if the compressor turbine is made of steel then it's from series 1 R33, if it's nylon then its S2 R33

Thanks for the help. Will look for the numbers on the housings and post back. Does this mean the the turbine wheel is more likely to be steel than ceramic? Is there any way of finding out?

Will have a look in the morning for the numbers and try the magnet thing. Lol nah im only looking at running like 15 psi max. still a stock block with just basic mods and only got a safc 2. Hopefully it aint to laggy or anything like that.Being that its only oil cooled whats the best way to ditch the water lines? Join them together or just remove and block off?

weld the holes on the bolts and screw them into the block without the pipes, problem solved =]

to me, it looks like a highflowed nissan turbo cause those wheels definately aint standard, especially the exhaust wheel..its HUGE

Without injectors & AFM that turbo is largely a fruitless upgrade.

In fact pretty much every turbo is, you need supporting mods for anything other than the factory turbo

Thanks. Yup I am looking into afm and injector upgrades. I have seen on these forums from the dyno results page of people running highflow turbos on safc's etc so would be interesting to hear from them. But am definatly aware and looking into investing in some injectors, afm and most probably a nistune in the near future.

Will post up numbers on the covers tonight when I get home. For those who want to know current engine mods are:

Full 3 inch Exhaust from turbo.

Apexi Pod Filter

Front Mount Intercooler

SplitFire Coil Packs

Nismo In Tank Fuel Pump

Safc 2

RSM

Aftermarket Light Flywheel

Excedy 5 puk clutch

12 Psi of boost

Stock Turbo

38mm External Wastegate

Am Looking at making around 230kw at the wheels or so.

I have read and been told i should be fine with stock injectors and might just get away with the stock afm. Am still looking into gettins a full aftermarket ecu to gain full benifts even though some have shown that they have run highflow turbos on safc 2.

Compressor Housing has 45v2 on it and I can not read the turbine housing. I think it might be OP6. Tried to look for a badge of some sort to see what internals were used but could not see anything either.

    • 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. 
    • 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. 😂
