Doing up a 77 280Z from scratch. The donor car had no injection system parts full stop. So starting from zero, what do the members recco on a complete aftermarket system for a NA build. Engine will be mildly cammed with head work, bored .040 over, flat topped pistons, balanced, and the usual easy upgrades. Is Megasquirt a complete system for someone like me or just an upgrade? Are there other complete kits I could look at? Not having a lot of luck with the usual searches and Z car specialty outfits.
