IC
HP Fuel Pump
Bigger Injectors
Standalone Or
Bandaids
Such as Timing control, 02 clamp, etc.
With 10psi I would rather want a standalone though.
A Bigger DP would be helpful.
A helper Spring

Thats all i can think of. Im tired.

it's a spring that goes onto the internal wastegate and runs parallel to the wastegate actuator. It should help with keeping a steady pressure instead of overshooting your target pressure and settling down towards redline.

Of course, I'd highly recommend going with a better actuator. I upraded to a gt28 wastegate and it helped with both spool times and controlling the boost levels across the rev range.

Thats all i can think of. Im tired.
FMIC, 1.8inj, MSD Timng Controller/Bipes, LC-1 w/ gauge for tuning, boost gauge, Begi AFPR, 255LPH HP fuel pump, boost controller.

Bigger DP/exhaust would help ALOT.

If you start seeing boost drop off, and aren't running INSANE RICH, you will need a helper spring. Too rich and you start losing exhaust velocity and it won't keep the turbo spooled up. I found that out the hard way this week.

They have a disk set that lets you go 2:1. 4:1, 6:1, 8:1, and 10:1. With 1.8inj you will probably end up using the 6:1 disk.

For the amount of money they charge for the set though (and for that matter each disc) it's probably worth it to just buy the BEGI add-on regulator for $199 and get rid of the Vortech. At least, that is my plan if I don't man up and do MS.

See the FAQ. Section 4.

https://www.miataturbo.net/forums/showthread.php?t=4288

190HP should be more than adequate for anything utilizing the Greddy turbo.
