ok, I have just been told that this is a SI turbo (I though the 45 v 2 on the compressor wheel meant series II) but anyway, this is good news because its a steel wheel meaning you can run more boost through it and it wont disintergrate like the ceramic ones.
I thought all R33 both series 1 and 2 have ceramic exhaust wheel and are limited to about 14 psi boost.
Series1 has a metal compressor wheel and series2 has a nylon one.
