oil pressure restrictor

[hawkwind]

G'day blokes  
Question for the turbo bike blokes ( or cars ) Im running the increased volume  oil pump (larger pump) for the busa ,not the the geared up version , does anyone use a pressure restrictor for the oil suply to the turbo ? does it require one ? no it aint one of those fancy GTr garretts
Been quiet lately mostly working long hrs for extra $$$ and in the shed building  
All the best for the upcomming speed week ,ya lucky bastards

ya dont need it. when ya increase the pressure you blow the coining out of the oil filters. the filters are the week link. ya dont need it if ya prep your crank and rods properly. secondly if ya increase 2 much pressure ( over 65psi) to the turbo you will definately blow past the seals and smoke the shaft.
