What Are The Garrett Equivalent P/ns Of The Oem Turbos?

[sonoramicommando]

Hi all,

Im wondering if there are exact (or loose) equivalent of Garrett turbo p/ns for OEM skyline turbos - like GTxx for rb20det and rb25det etc.

cheers

Different products by different manufacturers . All dimensions different , some mounting flanges aside .

ohk wo - so its made by nissan in-house?

in that case, does anyone have data on the oem turbos - like a/r, wheel diameter and what not?

has some pics with impeller dimensions to give you some idea.

compare that with published data at turbobygarrett.com to get more of an idea.

A/R of the turbos fitted to the RB20/25 engines was not given by the manufacturer, so it's a case of look and learn to a degree. The turbos were manufactured by Hitachi though I believe there was a financial arrangement between Nissan and Garrett for the technologies involved.
