well i know very little about the metro turbo and ive built and worked on a few rs turbos and the escort had a garret t3 turbo... is this the same? im asking as i have a fully rebuilt one with all the 360deg bearing and all balanced up sat next to me from my old fiesta project......
only pic i can see on photobucket but think its got a ar48 compressor housing on... cant remember!

its a long shot as its huge and lags a little on a 1.6 cvh! lol but if its a possible donor i might build a turbo lump

cheers dave
