That's a bit of a stretch of the current project I have on the go.
IRL EFR7163 + cressida + 1jz VVTi

Im hoping for full 23-25psi no later than 3k.

Step up to 245s, 200whp, and join us up in RA :)

Gotcha. I'm planning on picking up some more power but staying in RA for next season, and the following season shooting for ALLOFIT and GT class. I'm low on power for RA - if I just went down to 225s I could run in RB. I just want some more Miata company in RA next season :party:

Honestly for a 175chp goal, I'd be looking for an old M45 supercharger. I actually have one in a box at home right now as an intermediate solution until I have enough in the piggy bank for an EFR. Just need to get my MS set up first.
