T28 And T28Bb

[Kevs]

Hey guys,

I recently sold my R34 and got myself a silvia. I doesnt really know much about SR20DET as i drive rb for most of my life until i decides to have a change. I figure if you guys can gives me a clue of the t28bb turbo, does they comes with internal wastegate? i just couldnt source these information on google, so decides to get some help from you guys.

Cheers,

KEVs

Yeh definitely...

no factory car has ever come with an external wastegate... Not that i know of!

[T.D]

Yep, sure does come with an internal gate. T28BB is the ball-bearing version found in the S15s (bothADM and JDM models)

ADM s15s did not come with a bb t28, only the JDM models did.
