ka-t_Zenki, what are the specs on your setup? I'm thinking about buying another KA to build up and then drop it into a cheap chassis.
Oh and try a T25 on a KA... you think they spool fast on an SR? Try taking the same turbo that is stock on the SR and putting it onto an engine with an extra .4 liters of displacement. Lots of useable power in the lower RPM range.
details in my forsale thread, i have a much larger turbo than a stock t25
