Which Bullseye Turbo Is This ?

[2ndgendsm-md]

I recently purchased a bunch of dsm turbo parts and im selling what I don't need, however, I am not sure which turbocharger I have here. I was told it was a Bullseye turbo capable of 500 whp ? It is pretty large, but it has almost no casting marks to identify it... Id feel like an idiot selling a turbo I cannot identify, any help would be appreciated, thanx

Also, does anyone recognize this manifold ? It looks pretty sweet, and has a large wastegate flange, it is also not labeled anywhere...

Manifold is a OBX...turbo looks like a bullseye power 60-1

Turbo could be a 50,57 or 60 trim so the only way to find out is do some measuring and let us know.

forgive me for sounding ignorant, but what am i measuring exactly ?

forgive me for sounding ignorant, but what am i measuring exactly ?

Both turbine wheels and the size of the inlet and outlet.

ok, so heres what I measured:

compressor inlet - 2.75"
compressor outlet - 2"

I didn't take off the compressor cover (I have no tools at home) but I measured what part of the compressor turbine wheel was showing if that helps anything - 2 1/4"

also the exhaust wheel - 2 5/8"

note: these measurements arent perfect - also I measured the outer diameter of the inlet and outlet

any ideas ?

The size of the compressor housing leads me to believe its most likely a 57 trim, but it is slightly possible its a 60-1 with the "small" compressor cover.

Bullseye T04B 60-1, P-Trim turbine. 3" compressor inlet, 2" compressor outlet. Your turbine housing has a Garrett T3 inlet flange with a Garrett 4-bolt or 5-bolt outlet....it's drilled so either outlet flange will fit.

I used to have the same turbo in a DSM Bolt-On; ended up letting it go for the "right price" to a DSMer in need:
