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.

were you right? :D

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?

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
