try it.. lets see how long does it take for you to 'piang' your
engine and u need a new one.
fyi, turbocharger isn't a simple bolt on mod. you need to change to
low compression pistons, reduce the compression ratio of the
engine, piggyback the ecu, retune it, change a downpipe, slightly
bigger exhaust, add an intercooler, re-run piping and etc etc.
furthermore u need to upgrade quite alot of stuff. saying is easy,
doing is another...
if u really do own a supra, maybe u will know its not easy.
