chek it out.....oh the spool, i want one
basic rundown for those of u that dont know, twin entry turbo = two entry points for the pulses of ur exhaust gas from cylinders 1 and 4 and 2 and 3....twin scroll turbo = different. u have two seperate turbine inlets, one small, and one large, activated by an actuator, one for low RPM, one for high RPM, basically u get high boost at low RPMS and great spool. previously only IHI have done real good with this, it was also on previos rotors, but never really used well, then mitsubishi put one on the evo's, and one other company made one, but this is just beyond that, so much larger than seen before

I had to strip mine down for a rebuild... my CT20B had shitty worn-out seals. Firstly it had to have a steel wheel put in place of the ceramic wheel... once these come off you can't put them back on again.  While they were at it, I said to them (Precision Turbos) to hi-flow it - only cost a couple hundred more for the privilege, but will save me a heap down the track when I'd do it anyway. Turns out they couldn't hi-flow the stock CT20B as the bearings and housing and shaft were all too small, in their words, "it was a mess to rebuild". They snagged a second-hand CT26 and hi-flowed that instead. A 56mm steel comp wheel was put in, and as I understand it, the turbine wheel isn't that much bigger than the CT20B's so lag won't be a problem. It will come on probably 100-200 RPM later than the CT20B, which is what I can live with.
I got it back now, and it's being refitted up.
