I am helping a friend install a Vitesse Stage 5 turbo and I want to verify if we need an oil restrictor or not. Tried to reach John but he may be traveling. I think no but wanted to be sure. TIA

No restrictor is required. Only to be used if there is excessive crankcase pressure, causing the turbo not to drain properly. I would start without one, then evaluate.

BTW I did not receive any message(s) from you. If you need to get hold of me, email is best.

Thanks John! I sent a text to a number Jon gave me. He also tried to text. I will email any other questions. Thanks again!

I'm running my current Stage 5 without a restrictor and having no issues. My AOS is drilled bigger and routed to a catch can, which may help. For my 8v 3 liter, this turbo is a perfect match. Makes 1 bar around 3000-3100 rpm and keeps going up to 500rwhp.

I ended up having to run a restriction on mine.
