a wet system is the only way to go... dry kits use pressure to bump the fuel up through the regulator. a wet kit uses an extra solenoid that feeds off a fuel rail or some fuel supply and feeds it extra fuel. you should be alright with a 150 shot on that car as a max. you cna always retard the timing a few degrees, and colder plugs always helps as well. just remember dont spray it under 3k rpm, make sure you have good botle pressure.. around 1150psi... and its best to have a purge system on it , that way you can purge it before you spray it.
