We build injectors for Flyin' Miata. When the biggest name in Miata performance needs injectors, they come to us. The kits on this page come off the same bench in Tennessee.
To top out our line up of plug and play injector kits for Miatas, we followed the same formula from the FF640 kit and turned it up to 1100. Flowing at 960cc in NA Miatas and 1100cc in NB Miatas, these injectors will have you twisting axles and breaking 6-speeds.
We start with large batches of new OEM EV14 injectors from a Renault, and match them into sets flowing within +/-1% at both idle and wide open flow. With this size of injector there is a wide variance of idle flow rates for small engines, making careful matching essential. We then package them up with carefully designed components to make them plug and play in NA and NB Miatas.
Capable of 500+whp, these are for the truly insane. We think you'll like them.
Add a DW200 fuel pump to your kit above, shipping included. The DW200 is the best pump for most people. It uses stock wiring and requires no changes to your tune, and it delivers enough fuel to nearly max out FF960 injectors.
Plug and play for 1990-2005 Mazda Miatas. Requires standalone engine management.

Frequently asked questions
Will the FF960 fit my Miata?
Yes. Plug-and-play for all 1990-2005 NA/NB Miatas. Pick the variant matching your year (90-93 DW200 or 94-05 DW200, or skip the pump add-on with "No Thanks"). Standalone engine management is required.
How much power can the FF960 support?
500+whp on a built engine. The 960cc flow rate gives plenty of headroom for forced-induction NA/NB builds without the idle-quality compromises bigger injectors usually bring.
Do I need a fuel pump upgrade with these?
The DW200 (available as the bundle option above) is the right pairing for most cars. It's stock-wired, no tune changes, and delivers enough fuel to nearly max out the FF960. If you're already running a high-flow pump, the "No Thanks" variant is fine.
Can my standalone ECU (MS3, MS3 Pro, Speeduino) handle these?
Yes, any modern standalone works. Your tuner will need the dead-time / saturation / dwell values for proper idle quality. Reach out and we'll send the data sheet.
What's the difference between the FF640 and FF960?
Flow rate. The FF640 is good for around 300-350hp, the FF960 supports 500+whp. Pick based on your power target. The 960 still idles cleanly thanks to flow-matching at both idle and WOT.
