[bades]

Well guys i just got my rb20det in my s13 up and runnin.... im open o2 housing as im waitin on a downpipe.... well my boost gauge says im runnin 12-14 psi at WOT the wastegate and all turbo vacuum lines are fine.... i felt inside the turbo and looked at it and i believe it maybe a rb25 turbo.... are their any identifing marks?? other then the metal wheels....

if u did have a rb25 turbo u would only be boosting around 7psi. Its more than likely the stock rb20 turbo. The reason ur boosting higher is cuz you have no back pressure
