Here is the answer from GCG (for my RB25DET - may be different for M35):

1) We use the factory bearing housing and modify it, we do not use a Garrett "cartridge" as such to replace the internals.

2) Exhaust wheel = Stage 3 T3

3) Compressor wheel = T04E

4) A/R is same as the factory housings that come on the vehicle from Nissan, we do not modify, or touch any of the external housings on this unit.

As we are the only people who can build these units in ball bearing, we don't like to give away too much detail, i'm sure you can understand.

Cool, thanks for that Kiwi :P

Out of interest what model of Garrett (?) turbo is fitted to your RB25DET?

I was wondering if they were the same model that the M35 adopted.

I'm getting a bit excited in anticipation of my GCG High-flow :P

No the S1 Stagea turbo has a T3 flange but that may be the only thing in common. It doesn't seem to have a Garrett code on it, from memory it just says "Nissan" but its .40 A/R . The S2 had the neo engine with the GTT turbo with a bigger exhaust housing and the M35 as pictured earlier has M24N stamped on it as well as .60 A/R

Jetwreck has given me a rundown on what hassles I need to go through to remove the turbo and I'm not so sure I want to do it myself lol too much that can potentially go wrong and many things I can potentially break ;)

I think I might use a reputable workshop to do the dirty work, anyone got any suggestions of a workshop to approach for a estimate on doing it.

The turbo will probably be a week to two to get turned around, hopefully a workshop that can safely push the stagea to the side out of the way until the new turbo is ready to go back in would be ideal. I don't want to be getting the poor girl tray trucked all around the joint.

I get my spare turbo tomorrow. Yah. :)

let the learning begin.

Woo hoo! Sounds good.

If you havn't done anything with it by the time I ready for high-flow I may be calling on you :P

I was thinking about what you said and I'm leaning towards the turbo out & in in one day, especially if I can line the exhaust up at the same time. Would be the easiest way, then it's off to SAS for a tune.

I may have secured an ECU, just waiting to confirm they have a VQ25DET not a VQ25DE, considering it's an Australian wreckers I highly doubt they have a VQ25DE Stagea Half-Cut so it should be right.

Does anybody on here have a turbo charger for sale for VQ25DET  Garrett M24N  mines stuffed and has a cracked exhaust casing.  Was about to get it rebuilt but they discovered this. 

Thanks!

Have you tried Joe Kyle? Or the four or five Nissan wreckers in Auckland?

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
