here are some pics.
You can see that on the inside of the housing was written K-29 along with some other stuff I cant make out, and then machined

Very cool! You have a 2.5 right? I'm curious on how this turbo performs...

Doesn't a K29 not fit under a stock manifold? Also, wouldn't it have to have at least a 8 or bigger hot side which would mean LOTS of LAG??..

M Danger

if youd have read my other threads, id mentioned that is is a #8.
there was a little reliefe for the vac nipple on the bottom of the Throttle.

Sorry, I missed that M Danger. Is your car stock or modded? How does it perform on your car?

Was the shaft in fact broken and if so, did you figure out why? I read through you previous posts but didn't see that you'd followed up with the end result.

M Danger

I did actually, and the turbo was just fine. going to swap out the wheel studs tonight and give it a test drive, and put some real gas in it instead of couple year old gas.

hey what kind of vacuum do you get?

you know that this is a k27, right?

M Danger

the housing yes, the wheel is a K29, it was even marked inside, before the housing was machined to fit, by powerhaus

Check those wheel dimensions again, dude.

Looks like a K27 wheel to me. I had a K29 in my hands and it's a LOT bigger than 3" diameter.

well what are the dimensions of a k29 wheel??

I think we need to start using the term K29 Hybrid around here before too many more people get confused. A full sized K29 is much too large for a 951 motor, and AFAIK there isn't anyone out there running a full K29 on a 951.

Powerhaus builds K29 hybrids, and I have heard of various other builders that do as well. There are various ways to do it, though generally it consists of a K26 exhaust housing and turbine, K29 compressor wheel, and a K27 compressor housing that has been machined to fit the K29 wheel. I haven't personally seen any of these hybrids that actually use a K29 compressor housing, so I cannot verify whether anyone does this or not. Maybe someone else can, though it has been my experience that the few of these K29 hybrids I have seen in person use K27 compressor housings. Therefore the only real differences are internal, meaning it should have the same fitment issues as any K27 hybrid. There is a guy here in my town with a 2.8L, Motec, and a Powerhaus K29 hybrid (the owner of Speed 6). I've personally seen it and I can definitely say that it fits the profile of what I have described above.

A #8 turbine/housing should be the bare minimum for a compressor wheel with the flow capability of a K29. I believe the K29 compressor wheel is a 59lb/min wheel according to a Borg Warner website (can anyone verify this).

BTW M Danger, just FYI but the blades of your turbine have been clipped.

Edit: I have to agree with some of the others. That compressor looks smaller than the K29 wheels I've seen before, and more similar to a K27 wheel.

You have to have at least 3 1/4 across the exducer.

You are MUCH MUCH better off with this turbo. The K29 is very poor for a 2.5 951 - or any 951/968 nowadays. If you had one on your 2.5 you would hate it and remove it immediately because you need a 6 foot breaker bar to start the damn thing spinning.
I am not big on triple K's in general - but this one is probably the best one you could have for street/track car.

M Danger

thanks, yeah i thought the turbine looked modded, what difference does it make?
so does this look like a k29 hybrid?
k-29 is written on it as you can see at the top of the inside of the housing
