Not really...but looky what Daddy Zach has
stocker/stock turbine/tbird/t3t4 57 trim and turbine
comp and exhaust housing, comp wheel and turbine
small fine brass wheels do wonders to carbon/oil build up. the polishing on the comp housing is a standard 2.5 brass wheel....hopefully i will be able to smooth it out over time. the above, I worked on it over an hour of actual polishing...
