I have a '99 EK with JDM B18C.

I have a few things to add to my setup and I was wondering if it was okay if everything else was stock.

I'm having a shop install pr3 pistons, Crower Cams (stage 2), Crower springs/retainers, Skunk2 intake manifold, adjustible cam gears, and a dyno tune.

I was told I should add VAFC (or hondata), fuel pressure regulator. I can't afford those at the time, but will my car be fine for the meanwhile?

Is there anything else I need?
