Check Nopi to see if they have any injectors. Also there is a company called RC Engineering at www.rceng.com they can balance and clean your old injectors or get more flow from them, they also sell different cc injectors as well check them out you might find what you need.

RC Engineering doesn't "upgrade" injectors... it's not safe. The only way to get more flow out of the stock injectors is to up the fuel pressure, unless they're thoroughly clogged. Getting the sotck injectors cleaned and tested is a MUST in my book when you're dealing with injectors as old as ours or with used or off brand injectors. It's cheap insurance.

Anyway, the OP isn't looking for new injectors, he's looking for injectors that are compatible and higher flowing. The RX7 injectors are the only ones I know of. Just be sure to get the right ones. There's a different year that uses smaller ones with the same part number (how dumb is that?).

Thanks CRE I never knew that RX-7 injectors will work with Supras? What year RX-7 work with the supra?

Most top feed injectors can be made to fit, just a question of clips, impedance and type (peak and hold versus saturated), and whether spacers are needed for the injectors or if a riser is needed for the fuel rail and whether or not the rail or head need to be bored out... I can't remember the diameter of our injector inlets or outlets right now.

The first thing you need to be sure of is that the injectors are low impedance and peak and hold... low impedance + saturated is uncommon (unless it's a saturated injector and there's something wrong with it), so generally, if the impedance is low it's a peak and hold type and you're good.

I didn't think the RX7 injectors needed different clips, you sure? What's the flow rating, impedance, and what are the dimensions of those DSMs?
