Small update - my diff has now been received by SQS who are starting to put my new gearbox together, ready to ship over to me
I've also spent some time talking to LOBA Motorsport in Germany over the phone who kindly spared some time to discuss my plans for pushing more power from my Turbo Dynamics hybrid and what they may be able to offer while I continue to monitor Rob Smith's progress with his V2 K04 from CRT.
LOBA have been involved with a lot of development on various hybrid turbos, including the MTM/Dahlback K04 for the RS4 etc

Following up over email they advise I may be better off selling my existing turbo and starting from fresh as they can't account for the exact modifications and spec that Turbo Dynamics have installed.
They are able to provide an off-the-shelf K03 hybrid, the LO300 which uses the 2283 compressor wheel (which amazingly appears to fit inside a K03 compressor housing) with a clipped RS4 turbine wheel and accompanying modifications. Pics:
"How about that side boob? That turn you on?"
As the name suggests, this model is apparently good for around 300 ponies - though LOBA can offer varying degrees of spec using the 2277, 2280, 2283 and their own custom 2479 compressor wheel.
Knowing that the 2283 wheel is capable of flowing over 330 BHP with the correct accompanying mods I'd like to aim higher than 30x BHP, but the hotside will remain the limiting factor here, not forgetting the issues we've seen with surging on some other similar units from other companies which are actively being investigated further. It's all a fine balance.
I was told that my turbine wheel is a full trim RS6 wheel, though it's believed that this can't physically fit inside a K03 housing
Here's a pic I got the other night, where you can see it's not cut-back at least:
I'll try and get some better ones tonight when more things are stripped off the engine.
