If you could design a motor around the greddy turbo, then used n2o or exotic fuels, it could be possible.

Not on the average DIY miataturbo.net budget.

Another to the list....get rid of the Vortech. Either go Begi or a piston type, or go with a standalone. I'm seeing 15psi of fuel variance on my pressure guage depending on outside temps. The warmer it is, the less pressure I make coming off my vortech. I tested my clamping pressure today with the vortech out of the loop and my fuel pressure is stable and capable of 95psi. I installed a brand new Walbro GSS250 last year.
