1990 Miata

99 1.8L swap - 1995 ECU and wiring harness

stock 5spd with stock VLSD diff

Koni Sports with GC sleeved coilovers

205-50-15 Bridgestone Potenza RE11 tires - 180 treadware

Flyin Miata front sway bar - rear sway bar removed

Jackson Racing header

Cat removed

Custom Exhaust

Cone Air filter

Full interior minus heater core and blower motor and AC box.

Dry weight probably around 2200lbs (will be more specific later after I get it scaled)


More or less looking to see if there was anything for the 99 swap. Rules cover a 94-97 1.8 swap, but nothing beyond that. Also covers the use of factory wiring harness and ECU. Am I somehow going to be stuck going power to weight? or can a base class be decided for just the swap? Personally I would gladly start with the 99 miata base class and base weight and take points from there. Just want to hear opinions on this.
