i am installing a precision 62/62 journal bearing turbo on a 2002 s2000 was wondering am i supposed to run a restrictor?

thanks in advance

 

-4 oil feed line from relocation block thats on the engine block with NO restrictor and at least a -8 drain into the girdle and you wont have any problems. This is how mine is and I also have the Precision 6262.

 

Alright just checking, don't want to destroy this beautiful snail

 

i have a -3an line and no restrictor. you don't need the -4 line.

 

-4 line will work fine also. I've been using them on journal bearing turbo's for 6 years now with no problems.

 

well, those new precision turbos are pretty sensitive. They will not take a beating. May want to contact inlinepro. I spoke with Ya not too long ago and they made a semi oil restrictor because it looks like what is ripping up those precision turbos is high oil pressure.

From what i know the ball bearing units have no issues but I know for a fact the journal bearing ones do from first hand experience. Contact Ya and see what he recommends.

 

I called Precision directly a few weeks back to see what they thought about using a restrictor with their 6262 JB turbo. They, according to the guy I talked to, said the F20c engines 80-85 psi of oil pressure wont hurt anything and if I do notice a little bit of oil burn, then add a slight restrictor. He doubted very much that I would have any problems and said the main problem people have isn't with the oil feed, its the drain. Too many people put the drain in the oil pan when it needs to be in the girdle just above it.

 

Well I blew my first precision 62/62 with a -4 fitting running to it. I didn't even have 40 miles on it. That's y I started this thread to see what is right for this turbo

 

Where is you oil feed coming from and where is the drain going to? Is the drain in the oil pan and you're using a rubber hose of around 5/8" ID. If so, it cant drain correctly and the fitting used to slip the 5/8" hose over reduces that drain area to 1/2" ID and that is too small of a drain. It restricts the drain flow too much. Also, there is no good place in the pan to put any drain and expect it to work well.

 

my drain is the right size.. but where do you have ur drain running to if ur saying there is no good location in the oil pan?
