Well you can use any B series pistons except for the B20's in order to raise compression and make that bore a littler larger by .25mm. I posted a cam guide up top so you can check out which one would fit into your budget and goal the best. P&P I would go with alaniz/portflow/dpr. Bottom end work I would trust RS machines, Ericks, IB, GE. The key with the b16 is to have a light car, and make sure to get the proper gearing that came with that motor. As far as bolt on's I would recommend Comptech Icebox, either SMSP or Hytech headers, straight through 2.5" exhaust mandrel bent piping with a nice muff. Light flywheel such as toda, jun, fidanza, spoon and a decent clutch. Port match your Tb wtih your intake manny and head for smooth flow. 12:1 compression is usually max for street use but you can go higher wtih tuning from hondata. Little wide tires that are sticky and your good to go. have fun.
