If U don't want to mess with tuning the ECU buy a NOS or Nitrous Express 4 cylinder kit and a bottle heater, but you'll have to tap into the fuel tank, and drill and tap the throttle bodies to put in the nozzles, also I had to cut the crankcase breather cover down to fit the nozzle into the the cylinder closest to the clutches. It's a very involved install but it will perform better than boss or boondockers. You get a full 58hp with a 40 shot. Also once it is jetted for the HP you want, your finished, no tinkering with a control box, though you may have to reclutch it for the spray.
