GSR motor, Do I need a Restrictor on my GT35R? I know BB turbos need less oil pressure but I am running 3AN line so I dont want to have to little pressure. I would like this turbo to last as long as possible without seizing or blowing seals. What would you guys reccomend?

 

Ive read the Garrett BB turbos have restrictors built in.

 

with a 3an u shouldnt but im using a 4an on my teg with a sc61 without a restrictor and i have 30k miles on my turbo so its hard to say but ask the people that build the turbos they know what size is good

You are correct.

 

my precision 35r has one..just look at the oil inlet

 

I think as long as oil pressure is below 60psi your cool with the 3an from what the garrett site says. I just ran into this problem with a 2000 Celica, oil pressure is a bit high on that engine so a restrictor is needed.

 

i was gonna get one too, but i asked precision and they said they recommend a 4 an for my sc61
