I would definitely recommend the 4-2-1 header for sure, but I'm not sure if you can use the OEM crank pulley... you could try it, but the spacing might be off, thus possibly leading to premature belt wear, or worse, belt slippage and/or breakage at higher boost levels. Not sure on the throttle cable either, but good job going for the map controller vs. that lame relay!
