1 1/2 inch SU's were used on the XPAGs installed on TD MKII's and
TF 1250's.  It is used in conjuction with a milled and ported
head, the larger later style valves, altered ignition timing, and
few other alterations.  It is also best to fit the 1 1/2 inch
intake manifold, but the 1 1/4 manifold can be ground out some. 
The original air cleaner and it's plumbing must be removed and
individual pancakes fitted.  At 9.3:1 compression and high grade
gas the factory gives a 68 BH power output.
