If you want to stick with the toyota turbo's then they come in the following sizes.
CT9 lucida std turbo
CT12 toyota 1GGTE twin turbo 2lt petrol (bigger turbine but smaller compressor
CT12A 1JZGTE twin turbo 2.5lt petrol Bigger turbine and compressor, ceramic turbine wheel and very free flowing whilst also responsive.
CT12B 2JZGTE bigger turbine and compressor again ceramic turbine.
CT26 3SGTE 2lt petrol. Big twin scroll turbine housing bigger turbine and compressor. Would be ok for the second turbo on a 2stage turbo setup. The CT9 as the primary and the CT26 as the larger more efficient secondary.
Of course there is a multitude of turbos out there to choose from...
If I wanted outright power and fuel economy then I stick with my RB20 turbo on the van now.
If I want more torque in the low end with not as much topend as the rb then the GT2052V is good enough for me! There are some more potent or larger turbined variable turbos out there.
Basically the the garrett code GT20 means a T2 turbine, the larger the number the larger the turbine.
The 52 means 52mm on the major diameter of the compressor wheel.
The bigger the turbine wheel is will mean more power at the cost of lag.
