Anyone have this turbo? If so, what type of numbers can this turbo produce?

All this turbo is, is a ko4 with garret oiul and water pluming. its not a hybrid turbo.

Does it have the same shaft and bearings as the K04 or the T28?

A t28 is about twice as big as a ko4. theres no way they can cram a t28 compressor wheel into a ko4

Well it says that they use a T28 cartridge, doesnt that include the compressor and turbine wheels? Also, I believe the port out both housings to fit the wheels. I will e-mail them to find out exactly.

Unless they change the housing there no way in hell they could cram that big of a wheel inside a KO4. and if they changed the housing its not a KO4.

Let us know what they tell you...

Yeah man, I think they are blowing smoke up your ass. Or they just aren't telling the whole truth.

they arent blowing smoke. what they are doing is taking the center cartige and the compressor housing with the wheel trim of the T-28 and putting it on to the k04-15 exhaust housing. although they are deff using a diff compressor housing bc i know thats not a T-28 nor a k04. now as for the lag time im not too sure on how that would be effected considering u r puttin a hudge compressor on compared to a small exhaust side. i would kinda see it as the whole problem of using the k04-23 seeing it has a little larger compressor housing than the k04-15 but thats prob bc there isnt correct tuning software for its specifics. although there are venders that will program it to any specification u need. im really thinking about buying one bc there is upsolute tuning close to me.im tryin to get a price now though first.
