Having not been on here for a (ahem) while I decided to venture down to the basement
to see whats lurking down there...
I've found a V interesting turbo that I sorta remember buying but not what it was for,
one of my RST's or Cossie's DOH! Of course if I had any sense I'd have kept the invoice
but double Doh!
I think it's a hybrid, I can see it ain't a standard T3.

The casting marks as as follows,-

BCC2 A/R 42 GARETT
Any ideas?
