Those using nitrous jets for restrictors come in! Just seeing where you guys are starting when choosing which jets to use to restrict oil feed for turbos. I am a twin set up and have too much oil going to the turbos. I'm going to use just 1 restrictor in the main feed line and have no idea what size to start with. Thanks!

with a restrictor keep in mind you most likely wont be seeing less pressure, youll probably be seeing less volume, so you may want to put the resrtictors at the begining of each turbo and keep an eye on your drain.
bump. So i should put a jet in front of each turbo then your saying? Or one i nthe feed off oil block spout? And what size should i start with? Thanks!

Ok, i'll add some more info that may be useful.... My oil feed in -4 goes from the oil block thing above filter to a Tee just in front of drivers side turbo, then into the turbo, then the other side of the Tee has a -4 line going to the pass side turbo. Also these are journal bearing turbos, not DBB. This help a little more? Thanks!

I called Garrett on this subject years ago, they said to keep the turbo inlet between 5-30 psi during the whole rpm band. On my engine a .060 worked out good on the low side (above 5psi) but had a little to much high side (around 40psi @6500rpm). My truck now has over 60,000 miles on it with two different turbo's in that time. The one that broke was a overspeed problem (shaft sheared@ 25,000miles) not a oiling problem, the second one is still on it.

Verdad Gallardo so your saying i should use a .060 at each turbo or in the main feed line after oil block? Any way this could be too little oil and starve them or is that not possible? Thanks!

I use a 40 at each turbo. Are you ball bearing?
journal, i dont want to start too small and starve my turbos ya know? Just need to know of a refrence point to start that will be safe and if it'd be best to put the restrictors at each turbo or just 1 in the main feed. Gracias~!

I would put one restrictor at each turbo, maybe start with a pair of .080 and see if it smokes. If it don't smoke run it!!

What is the difference of putting the restrictor at the source (oil block) Vs. one at each turbo? How is each one different and what does each do differently? Trusted source Turbo Tech says it should be at the source, and W2W and a few others say to run it at the turbos like they personally do.... Is there a big difference? If so, what is it? Thanks!

I bought a function7 restrictor for my setup. I like it better than using a nitrous jet. I tried the nitrous jets, but they did not give me much confidence that it would not leak.
Ok, well im going to pick up some clear line to hook up as drain today so i can see what its doing to make sure its not the drain. If the drain is working good, then i'll try out a restrictor and hopefully can have it sorted out today. Thanks!

I have a .80 and it is still a little to big still smokes some but I tried without it smoked alot. I did a search and come up with people using from 80 to 60 so I went with 80 to make sure I had enough oil.
