As far as the standard cars go..
For drive-ability and economy: GT15, Bosch, HDi box.
For power: T2, Bosch, XUD box.
I had a GT15'd Lucas on XUD ratios off DumDum and it felt very nippy. On full boost by under 1800RPM at 20PSI all the way up to 4,200. On a modded bosch I presume it would be even better!
