Easy option = buy complete metro turbo engine


Non easy option = depends on his budget.


The T2 is a good turbo for a road going A series.


Personally i NEVER recomend over 100bhp on a road going A series though, due to the reliablity of the gearbox above that, and for that he is better off with something like an SW10 cammed 1380, which will make over 100bhp without any lag!


1275/1293 = best size for turbo, as said above, due to the block thickness


I would never build another a series mini though, better to put a modern engine in IMHO (like the 550bhp or so one im doing at the moment, see my sig)
