hey FI forum, need some help figuring out what these injectors flow and if they are peek and hold. They are both out of NA RX7s (the old *** lumps) all with red tops but 2 have red connectors and 2 have gray connectors. I picked them up from a local Junkyard for $20 for all 4 with clips All 4 have the part number 195500-1350 and DENSO on teh other side. I'm thinking these are Peak-Hold 460ccs but the connector color is throwing me off. Pic:

Thanks for the help!

No one knows?

It is possible. You just need to add a resistor for each of the Peak and Hold Injectors (essentially the same as adding the injector resistor box which houses the resistors). You'll need to leave the other two (saturated) injectors alone (without the resistor). Sorry I don't know the resistor value.

ECU does NOT matter. It always sends out the same data.

Everything ive always read bout the 7 injectors states that the second set of injectors is definatly smaller, somewhere closer to 240 or 310s.
Even though they have the same part number, i would definatly not just
throw them in until your sure. It is possible that someone replaced the smaller
pair with another pair of 460s, but dont count on that.
