I went and checked out the turbo this evening, i think my new turbo looks worse than this one.
The 51 has a polished compressor housing, very nice turbo and i would run it on my car, except mine is bigger:biggrin:
Should work great, 11.08 and no issues with the turbo. I personally helped Neil build the motor in this car many years ago with the heads never off, once a few thousand miles after it was cleaned up we installed the turbo.
No flat cams, and no popped head gaskets ran thru this turbo.
