i have a nonbb gt4294, does it require a oil restrictor?

 

Pretty sure that all turbos will require one in some way, Honda's produce upwards of 60psi of oil pressure at times, which is far too much for the seals on a turbocharger. Best thing to do here is to contact the manufacturer and ask.

 

yea i was just reading up on garrett's website, and they said you may or may not need one, depending on your oil return design design.
