dont really have a desire to spend that on a turbo tbh, i will go with the s1 or shanghai and then see how i feel about it.. i also would like to keep the option open to use as a DD..
If i get a kick out of it, i will likely be open to more improvements. Also as my understanding increases and i am more comfortable with it
As everyone else said, Megasquirt first, then everything else. The Megasquirt will let you make more power and get better fuel economy right away due to improved fiel and spark. You get to ditch the AFM and remove intake restrictions to let the engine breathe better. You can hear the intake growl when you stomp on the throttle pedal once you get rid of that stuff. You could actually do a cold air intake that pulls in cold air unlike most of them.
ask questions about how old it is. if the wideband pictured comes with it, if it includes the o2 sensor itself. if not i want to say a new sensor is about 100$
A new still in original package PNP is going for $500 on Miataturbo, an a lightly used lc1 for $120.
so 650 is high, if you could acquire it for under $550. i think you would be doing fairly good.
