the piggyback ECU is not that crash hot.
Radiator > oil cooler as water cooling is faster than the oil cooling.

BUt the other stuff bludger said is true, i'd get cams later. Also spoon cams are designed to be high revving N/A cams if i rem rightly. Not something recommended on a FI car.

If you can afford those items you should opt for no ECU from an AVO kit and get Hondata or PFC. The AVO kit is great for beginners but it has its limitations and is prob not the best kit out there
