From what I can see the best & easiest turbo to bolt onto a Mtdi is the K03/K04 hybrid wastgate unit that both Boraparts and Kermatdi sell. Basically its a Ko3 turbine with a K04 compressor. I drilled through the tdiclub forum & PM'd a bunch of guys there who have one & also talked to the folks at Kerma & bora parts. I was actually very surprised that the responses, of about half a dozen owners who replied all said the exact same thing. Good spool, 20psi and no issues. Its still a K03 hotside so its a bit constrictive at high RPM, I imagine in my van i'd be running around on the highway at 8-10psi so not the most efficient option from a EMP point of view. Also they have the stock K03 shaft, BUT from what I can see the K04's have the same 7mm shaft anyway. The best thing is if you have a rebuildable K03 around (I have 2) both of those vendors will give you a core exchange, $100 i think. Last time I looked they were around $700, not to shabby for a pro rebuild with all Garrett parts.

First, the main shaft of that turbo may be 7mm but the shaft diameter coming out through the compressor wheel is only 4mm! Second, that turbo is a Borg and Warner KKK turbo and Garrett parts will not fit in it no matter what size hammer you intend to use! These reasons alone is why I do not ever use a KKK based turbo in that frame size for a hybrid construction. My manual control unit is only weeks away from being released, I finally got my custom springs delivered for the boost control valve and the boost specific actuator will be in production very soon! It is only a very short time until everyone can install manually controlled VNT turbos in their M-TDI's Less than 2 weeks by my calculations!

would a K26 be any good? ive got one spare and i was gona run it in my corrado 1Z?also anyone know what power a gt15 (not VNT) is capable of producing? after loosing my fight with VNT im never going back to that
I'm curious about the K26 if anyone run one before.

Weren't the K26's on the 5 cyl audi gas burners?
