Well i just say if the rear is damaged - why/how? Something must virtually have gone through the engine for that. Comp wheel a bit more common but turbine isn't.

Cartridge might be damaged, totally depends on what is actually stuffed and how :)

Cost - depends on the above.

Actually Ash I'm not so sure about the turbine being the harder part to get , the GT compressor wheels are actually modified spec big center section diesel turbo parts . By modified I mean they have a smaller bore hole through their centers so its not like you can top and tail a truck one and bolt it in .

I went through this years ago with Brett - trying to find ways of getting smaller trim comp wheels into GT3076R's and GT3582R's . Some of the truck turbos have the wheels I wanted but no one wanted to bush back the bore size to suit the GT25BB sized turbine shaft . In other words the appropriate wheels are unique to these BB cartridges .

If you can get in good with someone that mixes and matches BB turbo bits you stand a reasonable chance of getting some of their components .

The thing is that if the turbine has had a big lose it may have struck the inner bore of the cartridges bearing housing and damaged the section that the turbine end piston ring seal runs on . You really need someone who assesses these things to pull it down and say yay or nay . Once the turbine housing is off gutting the cartridge is a reasonably quick and simple operation - in other words not much labour time .

The trouble with damaged turbos is that you can end up with something that owes you nearly as much and sometimes more than a new cartridge or unit .

I more-so meant the turbine was harder to kill.

Being you have

1. Air filter

2. Comp Wheel

3. I/C

4. T/B

5. Motor body

And whatever else in the way - to mince a turbine wheel just raises questions in my book :)

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
