It's not the same, there are slight differences.the all trac celica has the SAME ct-26 as the supra's except the water and oil passage pipings.
This may interest you.SlimFastSupra said:... The ST165 has a bigger wastegate flapper door (a little know fact). It is theorized that the exhaust A/R is smaller, but there is no data. You can physically see the snail section being larger on the supra...
A/R ratio only refers to the exhaust housing/turbine, and is independant of the compressor side.Racefiend said:But they are not. THe supra compressor is actually quite a bit bigger than the celica ct26. So I wonder if that test is valid.
What?Racefiend said:But the larger compressor would have a larger rotating mass, and I would think it may throw off your readings due to resistance changes. How much I don't know.
