Before my most recent build, my car saw about 400-500 miles. I was running a -4 feed line to my SC-61 and oil pressure gauge was reading 50-60psi at the most, no restrictor. Now on my most recent build I'm reading like 80-90psi on cold starts and 40-50psi at warm idle. Haven't driven the new build because I'm waiting for a tune.

A) How badly do I need a restrictor?

B) Was driving 400-500 miles w/ no restrictor but lower oil psi numbers enough to damage my turbo?

 

i drove like that for years and thousands of miles without any problems with a -4 line and no restrictor. now I have a GT turbo with a -4 line and the built in restrictor in the turbo and its fine too.

depends on how good your drainline is too, but since I've always had a topmount, i've always had a good drain angle.

don't read into the bandwagon too much.

 

I tuned a car with a -4an line today and a decent return line. Its turbo was literally spitting oil out of the compressor housing . I'm sure the turbo wasn't in the best shape in the first place though

^^^I forgot to mention this part to you McLude.

 

Yeah, see my drain line is **** diesel and drains straight down and into the pan. I guess that's good?

**** diesel is no good man, Diesel is out...Methenol is in. Good is: straight down, short/direct as possible is good, no kinks, no part of the line being level or at an upward angle.

 

how big of a drain tube do you guys use?and does it matter on size of the turbo too ?

 

curious also, im wondering if i should just run the oil restrictor built into my GT35R, with a -3an feed and a -6an return

 

I think i'm running a -10 return, straight down, and short.

-10 is basically the common size, and is generally considered the minimum. That doesn't mean you need to do a bigger size though.

You might want to change that out. That -6 return is way too small.

 

-10 return into my moroso pan. its directly down, at like a perfect 45 to 60 degree angle.

if you are worried about it, just buy an inline restrictor, atp turbo sells prebuilt ones that bolt right into the turbo.

 

so -10 return is what i should be doing then, i still havent done anything yet

 

i ran a standard garrett turbo.. t3/t4 non bb, with the oil line kit from fastturbo, the drain is short and sweet, perfect angle too, i used 2 45' pieces, and the feed was whatever lenght size came in kit. no problems here.

 

personally I didn't have a problem, but I do know someone who ran one and messed up his turbo seal.

Compared to a -6, yes.

 

14mm+ ID on the return is best

i was wondering about the -3 and -4 feed. Usually we have always used -3 on non bb and now with dbb turbos some were saying -4 with restrictor but i dont see whats wrong with -3 with restrictor.. we havent had any problems.

lmk what you think.

 

A -3 with a restrictor might work for you....it would just restrict the flow a little bit more than a restrictor on -4

 

a -4an killed my first xspower 57 trim.. now i run ATPturbo.com restrictor

 

im havin kind of like the same problem cause it seems like my turbo is being flooded with oil and literally pouring out from the exhaust side...i have a ramhorn manifold and running a -10 return line and the small feed line...wat kind of restrictor would i need?

I just got one in the mail. This one to be exact. Anything special I should know before installing it? Is it pretty straight forward?

Just goes between the fitting in your turbo and the turbo.... funny they make it like that... they should make it a male on both sides that way you dont have fittings stacking on top of each other. I use that white tape for all fittings even if you dont need too, to keep things leak free. I also use lines from Stan with female on both ends so you could have a different line.

I just talked to Stan at fast-turbo and he is getting the male/male fittings made at their shop soon for a good price.

I think 14-15$ is too much.. here is one.. 13mm or 1/2 wrench will tight it down... this is a -4 fitting for gt35r and like DBB centers

Oh man, I like that one. My fittings are already stacked tho... The male to male is much better I agree.
