Jason062100 Posted March 25, 2020 Share Posted March 25, 2020 I got a Gt3076r for my RB25DET. Does anyone know if there is a built in oil feed restrictor or if you need to do that separately. I can't seem to get a straight answer. Link to comment https://www.sau.com.au/forums/topic/480024-gt3076r/ Share on other sites More sharing options...
Murray_Calavera Posted March 25, 2020 Share Posted March 25, 2020 None built in, you'll need to do that separately. Link to comment https://www.sau.com.au/forums/topic/480024-gt3076r/#findComment-7927167 Share on other sites More sharing options...

Murray_Calavera Posted March 25, 2020 Share Posted March 25, 2020 (edited) Too easy mate, this is from Garret's website - https://www.garrettmotion.com/racing-and-performance/choosing-a-turbocharger/turbo-system-optimization/ Oil Supply & Drainage BALL BEARING TURBO An oil restrictor is recommended for optimal performance with ball bearing turbochargers. Oil pressure of 40 – 45 psi at maximum engine speed is recommended to prevent damage to the turbocharger’s internals. In order to achieve this pressure, a restrictor with a 0.040” orifice will normally suffice, but you should always verify the oil pressure entering the turbo after the restrictor in ensuring that the components are functioning properly. Recommended oil feed is -3AN or -4AN line or hose/tubing with a similar ID. As always, use an oil filter that meets or exceeds the OEM specifications.

Jason062100 Posted March 25, 2020 Author Share Posted March 25, 2020 I heard somewhere that some of them came with oil restrictors built in. Is that just straight up wrong?

Murray_Calavera Posted March 25, 2020 Share Posted March 25, 2020 I'm hesitant to say 'it's wrong' as I don't really like absolutes... However, I don't see how they could incorporate an oil restrictor as there are different sized restrictors for different applications.

Murray_Calavera Posted March 25, 2020 Share Posted March 25, 2020 Ooo just found this - https://www.turbosmart.com/product/opr-t40-40psi-blue/ Oil pressure regulator for your turbo, very sexy. Then you don't have to worry about correctly sizing your restrictor. Nice.

John iatrides Posted June 11, 2020 Share Posted June 11, 2020 No you gotta buy the oil restrictor it doesn't come with the turbo I had one on my gtx3076r. Link to comment https://www.sau.com.au/forums/topic/480024-gt3076r/#findComment-7932821 Share on other sites More sharing options...
