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.

 

It ain't easy.

 

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

 

i want to stay in rb for next season then after that go to ra. So the plan is vvt swap this winter then turbo the vvt next winter

 

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

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.
