Have a buddy keen on upgrading his '01 summit highmark 600 to an 800, has anyone done this swap before? Already lengthened the track to a 163 and the power just isn't adequate compared to the 144 track. Would the exhaust, wiring and dpm all need changing? Turbo or nitrous on the 600 would likely be a train wreck, any advice would be helpful.
