Are these the right ones for my car?
 

Wanting to get some 720cc injectors for my car and wondered if the Greddy ones on Rx7store.net drop right in with out having to modify anything

Thanks!

Sorry no sleep make me forgetfull, i have a 87 RX7 TII

yes those will work

since you have a 87( they switched impedance in the middle/late of that yr....) do you have the resistor pack in the front of the engine bay in the pasenger front corner underneigh where the stock air box goes??

if you DO have the resistor pack then those are the right ones. as you would have low impedance injectors.

if you DONT have the reistor pack then your going to have to use a 10 watt 10 ohm resistor inline with those injectors as they are low impedance ( well the ones u showed us)
