Toyota CT15B Turbo

Posted on 21 January 2012 by admin

CT15B-Turbocharger The CT15b Turbo is one of Toyota’s well engineered blow dryers capable of providing 400hp, It was designed purely for 1jzgte to eliminate the twin turbo setup without loosing response or power but it also improved the maximum torque by about 4% and is 25% more efficient than ct12 setups.

A stock CT15B is rated at 400hp / 225KW and once high flowed it can snap out 450hp / 270kw, the stock unit has a max boost of 16 – 17psi. It is common practice to see the CT15B high-flowed, one option is to use a 20G compressor and bore the comp cover to suit, this will give you he 50 -70hp increase and as the 20g compressor wheel is a better mapped for volumetric efficiency you will have one super responsive turbocharger.

It uses Toyota’s own flanges on the exhaust housing inlet and their 4 bolt rectangular outlet and incorporated a internal waste gate that will open a 6-8 psi depending on the year and model of car. Its not a twin entry and 90% if the CT15s run ceramic technology and are both water and oil cooled. Looking at the dimensions of the compressor and turbine wheels it is very similar to the CT20b and it probably is one of the best turbochargers Toyota has developed.

RRP $1200 ($300 Secondhand)
