dzieki za odpowiedzi i znowu zdania sa podzielone

jak bede mial w lapkach ja dzis to obejrze sobie wejscie a pozniej rzuce moneta w sprawie dorabiania restrykcji bo i z nia i bez niej turbo jezdzi. pytanie tylko jak dlugo.
ja przechodze z t28 na 2560 i pamietam ze przy montowaniu starego turbo cos sie dzialo z odplywem wiec teraz powinno byc dobrze.
tak wogule to nie wiem czego sie spodziewac po tej sprezarce.
kupilem 'po kosztach' za 3100zl z papierami od kumpla. tak ot to okazalo sie ze na polske garrety rozprowadza moto remo z ilawy
na garrett turbo tech znalazlem takie cos
Ball-bearing turbochargers can benefit from the addition of an oil restrictor, as most engines deliver more pressure than a ball bearing turbo requires. The benefit is seen in improved boost response due to less windage of oil in the bearing. In addition, lower oil flow further reduces the risk of oil leakage compared to journal-bearing turbochargers. Oil pressure entering a ball-bearing turbocharger needs to be between 40 psi and 45 psi at the maximum engine operating speed. For many common passenger vehicle engines, this generally translates into a restrictor with a minimum of 0.040" diameter orifice upstream of the oil inlet on the turbocharger center section. Again, it is imperative that the restrictor be sized according to the oil pressure characteristics of the engine to which the turbo is attached. Always verify that the appropriate oil pressure is reaching the turbo.
The use of an oil restrictor can (but not always) help ensure that you have the proper oil flow/pressure entering the turbocharger, as well as extract the maximum performance. "
