I know a guy with an ats gt2860rs kit making 300awhp thats wanting to upgrade to a gt3076. Dunno if you'd be interested in his kit....?

You can get kits with adapters for the std manifold. A gt2860 will get you low 300hp and be super responsive.

anyways my engine is pretty good,
40 thousand on it,
just needs forged internals, but pulled 160psi on all 4 cylinders.

If you are aiming for 220-230rwkw I think you should be looking for a larger turbo GT3071/76 etc

oh yeah of course not but i plan on only having a mildly built car
aiming for 220-230rwkw
with a standalone, exhaust, tune, mild cams, fuel pump and injectors, liquid injection, intercooler etc :) nothing major/

i highly doubt you will get 350whp from a twin entry ct variant. definitely not without a rebuilt engine, cams and an aftermarket ecu etc.

a 20b is a good upgrade over the ct26, it will hold decent boost to redline on a stock motor

dont waste your money on a ct27, there are supposedly pretty laggy with the wheel upgrade. you best bolt on is the blitz k1 380v and good luck finding one!

Fair enough,
Just want to out something on there that will bolt on and hold boost right up to 6800 and hold about 350hp
Unless someone can suggest anything else I could use I think a 20b or equiv hi flowed 26 would be fine for my application
I was leaning towards an ats ct27 but bit expensive for what it is

Did the person you're looking to buy it from have it rebuilt themselves? If so get all the details you can, as others have said above it looks to be a rebuilt CT26/"20b". If the seller doesn't have any info on it (came with the car etc) see what else has been done to the engine and if they have a dyno chart so you can see what it performs like, to give you an idea if it's a standard rebuild or a hiflow.
Another option would be to phone GCG with the info stamped on the turbo and see if they can give you more info on what was done to it (and when).
If it's been hiflowed it will likely have upgraded internals making it a little more laggy than a stock turbo in most cases, but able to produce and hold more boost at higher revs; the last pic you posted looks similar to the steel wheeled ST205 CT20b wheel.
CT20b's aren't amazing turbos by today's standards, plus they are all going to be at the very least 13 years old so don't expect crazy drastic improvements over a CT26 or finding one without shaft play that hasn't been rebuilt, but in saying that they are better than a CT26, just some food for thought.

Those are the only pics I have of it
Probably a rebuilt ct26?
Worth buying? Says has no shaft play etc
Was being driven on 14.6 psi.

If its a 20b I'd be keen a hi flowed 26 tho are those as good as a 20b?

Obv been rebuilt, prob hiflowed with a steel turbine.

Comparing it to the pictures I took of mine CT20b today it looks very similar. What does it say on the comp cover? Toyota or CT26?

Do you have a pic of the comp housing?
Almost looks a bit like a ct26 from those photos. Can't get them full screen on my laptop.
