Compressor housing - .42
Compressor wheel - 45 trim.
Exhaust housing A/R .36
Exhaust wheel - not sure probably 68

Thats whats I have in my head...

AFAIK Cossie 2WD with 0.48 exhaust and 50 trim compressor, and 4x4 with 60 trim compressor, T34 with 0.63 Ex. housing....

Dont quote me though!

Be interesting to sort a definitive list of Ford Turbo specs between 82-97
