93 ECR33 GTS-25t RB25DET turbo charger adapter plate between turbo and exhaust manifold

[twr7cx]

My recently purchased 93 ECR33 GTS-25t RB25DET looks to have an adapter or spacer plate in-between the turbocharger and the exhaust manifold. Is this a normal fitting or indicative of a turbo charger change?

Thats not a stock turbo, no not a stock fitting.

Sometimes used to space a turbo out so it doesn't hit stuff.........sometimes used for a different pattern turbo  eg T4 to T3 etc.  As Hardsteppa said, not standard.

Is there usually details on the turbocharger to identify the model? With some of the aftermarket VNT's I've used on diesel engines they usually have a plate on the front inline with the waste gate actuator.

normal for gt30 upgrades years ago. should be an ID plate on the cartridge
