> There is a cheaper option. Buy a Turbo Metro-MG for about £50 ($90) and
swap it all over. Guy I know fitted one and ripped the ends off the
splines, fitted race hardened ones and ripped the ends off the splines
again. A modded Triumph Toledo (I think) axle is in the process of being
used. I could get some turbos organised if anyone is keen on trying.
Cheap fun!
