The ct20 is even smaller than the ct26 and is generally expensive and a POS as it was rigged up to exhaust hardlines, instead of something that would flex.



I dunno what that thing is you've got.. Frankenstein turbo!

 

Thats surely not a CT20, i can bet on it . i already have one ct20 in my garage and its a lot different. A lot smaller with smaller fans and smaller compressor housing. My turbo is definetly not a CT20 but i dont know even if its a CT26 cuz there is no sign of grinding on the compressor housing at all. but the compressor side(from where the boost comes out) has a different face welded on to the turbo. same is with the turbo housing flange. T3/garrett flange has been welded onto it.
I measured the compressor fan. Its around 6.6cm exducer and 4.7cm inducer. pretty close in measurements to 16g.

Ihave completed installation of this turbo on my B16. will post the pics real soon.
The reason why i've replaced the 16g is that my 16g doesnt builds up the boost at all . i had to replace it with another turbo and i got this toyota turbo for free so idid

 

Yeah that compressor housing is pretty odd on that turbo. Could that inlet be something someone fabricated?

I don't know just my .02
