guys,

I have some CT26 turbos at home and noticed that I have two different exhaust housings and wheels. One is larger and the other one is smaller!

Are there any other housings I can use which are small due to my small one is cracked? I read that there is one for the ST165 from Turbonetics but is there anyone out for ST185 too?

thanks in advance

Mario,

It seems as if you have a single entry CT26 from a Supra (the bigger one with a 4 bolt discharge flange) and a dual entry CT26 from the 2nd gen 3SGTE (6 bolt discharge).

I dont think there is a replacement turbine housing for the 185 similar to the one turbonetics sells for the 165.

both have the same flange and are twin entry! I talked about that to my turbo specialist and showed him the housings and he said that they are different!

As I wrote, one is smaller. But both are twin entry and have the same flange and bolt pattern!

I'm not really sure if the upgraded ones als use different exhaust housings?!

The smaller one is probably a ct20b. they had a smaller turbine and a smaller compressor also.
hmm it is not the CT26 that is smaller than the CT20b?
the CT20b is a much more better turbo
