in issue 75 of zoom, there is an article about a buggy with a twin turbo 1MZFE. for a while they ran it stock with twin T25 turbos and medium low boost... had bout 150KW at the wheels, and that was not pushing it at all....
they built the motor with some new innards and some GT25 and made like 450 or something KW...
they are used pretty often for race engines in the states too...
they have certainly got some potential, as for mile mods, i got NFI really
hope that helps somewhat...
