Point is the ct26 is more than the stock 5s can handle for sure... and it has a little faster spool up time than the t3... because it is meant for a 2.0L low end torque MONSTER! biggrin.gif

Which is why it's too small for a 2.2L; you have increased air volume going through the turbo- THATs why 13 psi is out of the efficiency range for a ct26 on a 2.TWOL engine

Shid read up on turbo performance alittle more... I think you are forgetting some things. First of all... 13psi is 13psi. A 2.2L engine is going to be able to reach 13psi QUICKER than a 2.0L. It doesn't matter how big of an engine you have... it doesnt govern the turbo's performance abilities... the design of the turbo is what determines its efficiency range. The ct26 is the first turbo on the sequential twin turbo setup in a supra... which is a 3.0L It is able to spool the ct26 WAY faster because of the increased volume of air... it still begins to choke around 17psi... and 13psi is still its most efficient zone.
