>I am not very mechanically proficient, which kit is easiest to install? SMC by far. It typically takes about 1 hour to unpack, install and get up and running.
It took the mechanic at Full Function *5 hours and 35 minutes* to install my SMC kit (not including any tuning, or even testing the pump to prime it and see if it worked). He started work at 10am and finished at 3:35pm.
