1990 Mazda Miata
Current Modifications

At a recent dyno session (5/16/99), these are the numbers that turned up:


206 hp at crank @ 7700 rpm
177 ft/lb torque @ 6150 rpm


I am still searching for that last bit of HP, my future plans are to go with a set of throttle bodies sometime before the end of the year.  Current candidates are either TopEnd Performance's TWM kit or the kit Dealer Alternative has or might one day have: With a bit of further tuning I think that 200 hp at the rear wheels is possible.
