the compressor housing has a A/R 60 w/T4 inlet and it looks like it's mated to a mitsubishi or other cast manifold. I dont know what size the exhaust housing is but the wastegate actuator is on the back. I'm guessing this is something that is normally run on a DSM. Also looks like the manifold is coated.

early buschur 3076 kit.

Thanks man! I was thinking it was probably a early BR kit.

This car is a complete frankenstein.. It's a 03 GSR and it's got a Evo IX MR drive train (except the head) - including 6 speed. IX interior. AEM standalone. Pretty sure the turbo is blown seals.. smokes like crazy.

Yup that is definitely the buschur manifold and with the internal wastegate it is probably the 3076 kit...Dave did do a few custom turbos to try and make various kits and ended up selling them off, so there is a chance it could be a custom setup.
