And now I present a freshly rebuilt Gen 1 CT26 turbo (single entry), complete with a mild T04E/46 compressor upgrade, a 7M-GTE turbine housing swap, brand new seals, and full balancing. See where the compressor housing inlet was bored out and slightly ported for the T04E/46 compressor wheel? And here is the turbine housing from the Supra 7M-GTE CT26. It is has a larger A/R than the original Celica 3S-GTE Gen 1 CT26, and will, therefore, allow a greater CFM relative to back-pressure than the stock housing. This may hurt low-rpm spoolup, but that can be offset with an unrestricted turbo-back exhaust upgrade.
