I have a 1991 square nose ski with a 2002 engine. It has recently installed foot wells, bilge pumps, ride plate, star bar etc. I am interested in adding a B-pipe, trim and msd enhancer. Even though my ski is old, it has a great 2002 motor. My ski is sooooooooo reliable. I was wondering if you recommend the additions. Another company recommended ADA head with 35cc Domes, the msd enhancer, factory b-pipe and freestyle porting. I think i also want the trim. I am also considering Wamiltons stage 2 upgrade. thanks in advance.
