So I put twin turbos on my 350z and it is smoking like crazy especially when you hit about 2500 RPMs.. it is using oil like crazy as well.. I have noticed that oil is blowing through my charge pipes and dont know how to stop it. It has a catch can so that isnt the problem.. I have also noticed that when it hits between 3000 and 4000 RPMS it starts to sputter and has a hard time getting above that.. but once it does it doesnt sputter.. it has the full greddy turbo kit and the profec boost controller.. if someone can give me some ideas that would be great.

 

Sounds like seals are gone in the turbo, or the turbos are not draining properly, its seeing to much backpressure and blowing past the seals.
Just my 2 cents

 

w a car like that, youd best be on first name basis w people at a local shop that deals in boosted VQs.

 

Yeah that is what im afraid of.. they are brand new turbos have less than 100 miles on them. But thanks for your help

 

Ball bearing turbos? Did you install a 1mm restrictor on the feed line?

 

Need appropriate restrictor on oil feed, depending on the turbo.
Need to release crankcase pressure. See catch can threads in FI section.

 

since when are greddy turbos ball bearing?
