Intro/progress on my turbocharged 97 STO
Hi all,
I figured I would do a small introduction, build progress, as well as get into some technical aspects of my new to me car. I have been a Mazda enthusiast since my dad turned me on to rotary’s. I have a T2 rx7 and a Rx8 in addition to my 97 turbocharged STO Miata I picked up recently by telling myself it would be a daily driver. The car was purchased from a long time autox friend for what I thought was a good deal. The car is pretty modified having a full begi s4 kit, MS Pnp, torsen diff, 6 speed, and other supporting modifications. The car was dyno tuned at 11psi making 240 whp and 220 ftlbs tq.
After purchasing the car I began the “initial making the car my own” process. The paint was very neglected which I remedied with the mirror glaze m105 and m205 combo. After a full interior and exterior detail I did a brake job and installed a new thermostat.
The next project to tackle is the tune. The car is currently getting 20 mpg on the highway which doesn’t help with my “ It will be a DD” concept. Also I would love to get the boost and overall power output to more conservative numbers (Thinking 6-7 psi). I am hoping I will have greater peace of mind when at autox and the annual matg trip. I have been viewing many of the Mega squirt related information on this forum which has been very helpful. I would like to post my fuel and timing maps as I believe that my timing map is on the aggressive side. The tune on the car currently resulted in great power at a safe air fuel ratio but has poor drivability. The biggest contributor to this is that the fuel enrichment on throttle tip in is not setup at all. I have found a great How To on DIYPnP website on tuning this but would love to see some Miata specific values/map to get me started.
