*You will need injectors,
*get rid of the power fc cause there are much better ecu available now,
*get rid of the n1 pumps as the oil pumps are a time bomb waiting to break and the water pumps cause over heating in traffic
*adjustable cam gears should be one of the things at the top of the list
*dont worry about the crank collar till you rebuild the engine
*the dump pipes find the biggest bellmouth ones you can and run them, also jap exhaust tend to have restrictors in them and custom made exhausts end up flowing a hell of a lot better
