looking at the specs on that, the turbine wheel is the same size as what's used for the 4.2 litre 1HD-T 80 series landcruiser engines.
That's not necessarily a problem by itself because turbine characteristics are also very much dependent on the #cm2 specification on the turbine...
So, you might have no interest in the technical stuff, but you're asking advice from people who can actually give you some useful recommendations, IF you provide them with the technical info.
All you have to do is link a page. You found your way here, can't be that hard to do.
There's wires crossed here.
60-1 is a reference to the compressor wheel and housing.
CT26 was produced in several variants. Turbine housings vary a lot from one to another.
The *cm2 size of the turbine housing is equally, or more important than the compressor wheel size. Although, both need to...
The turbine housing specs will be the most significant thing that affects how it will perform on a 13BT.
post a link to the specific turbo you have bought?
