Okay. Yeah, remove swaybars. Swaybars work by lifting a wheel; you go into a corner, the suspension compresses on the outside corner, and the swaybar forces the inside corner upwards, keeping the body flat. This is fine on tarmac when you're trying to not corner on the sidewalls. But on dirt, traction is far more important than bodyroll. When the surface is uneven the last thing you need is for a bump on one side of the car to raise your other wheel...I bet you gain half a dozen positions with that one mod.
Stock injectors? Yeah. 15psi should be safe assuming you've got a handle on getting more than stock fuel. I used to run 15 with 17 psi spikes on my bpt gtx with stock injectors, vj20, and an FCON. Took overall stage wins with it, too..
Miata diff fits, dunno about it being a drop in fit though. The viscous LSD's aren't all that great, but prolly better than a stock open diff.
Your strut inserts are fine, but maybe you're running too much spring. I think I've got about 250 in front and 185 in back, but then again that thing's got at least 3" more suspension travel than stock. But if you have themthere cool rally golf bilstein inserts, they are up to the task, and might work better with less spring rate.
Engine oil? Redline. Trans/diff? Torco RGO 85w140, or a mix of redline MTL and heavy shockproof. You should see pretty much the same oilpressure and engine temps on a rallycross as you do going down the freeway. If oilpressure is less than 20 at idle you're about to have a problem, and it better be at at least 40 when you're thrashing it. Stick a bottle of redline water wetter in the radiator, and that should be all you need. My GTX had a totally stock cooling setup, right down to the fan, and the radiator was totally hidden behind a freaking huge saab 9000 intercooler, and it never overheated, even on long , like 20 mile long, stages.
