Complete Vishnu kit minus injectors.
Ran it for about a year and moved to a hydra.
Comes with everything you'd need to run a turbo setup. I have electronic copies of the miata installation manual as well as hardcopies of the original manual (new versions are online).
Off the top of my head:
water temp sensor (and tee fitting for water line)
air temp sensor (not used--a new one came with the hydra)
GM knock sensor (not used)
crank trigger wheel and mounting hardware
crank trigger mount
crank trigger (newer 1/2" version)
magnecor plug wires for Tec3
DFU (two-coil ignition unit) and mounting hardware
two main wiring harnesses (pre-loved, of course)
DFU wiring harness
all the software and documentation you can eat (via EM's website)
Proven engine management for only $650 plus shipping!
PS I post pictures and more detailed parts list if you're interested.
