It would start and run, but it would be very lean under boost. The result would likely be a blown engine.

paying attention to impededences and such, yes it will start.
Dont reccomend running it like that though. the non turbos are 460 while the turbo injectors are 550. youd go lean and blow the motor
unless you use gls-se injectors at a 680cc... those are still NA

just asking. my friend gave me some n/a injectors instead of TII injectors because i thought my TII injectors were clogged.

after changing the injectors, the car refuses to start. it cranks and cranks and cranks but doesnt start. ive pulled the egi fuse and tried, pulled the plug under the steering column and tried, but nothing. i even tried pulling the leading plugs and adding a little motor oil in but nothing.

should i try atf in the leading plugs?

i THINK these n/a injectors are high imp, but for some reason they arent purple.

my TII injectors=purple, high square, with the key offset

my n/a injectors= red, high square, with the key offset, but the rx7 FAQ stated that the cap should be purple?

stupid question, but how would i go about checking it with the injector plug plugged in?

edit: or would i just test via the two prongs on the injector itself?

I am running 460cc N/A injectors for secondaries in my t2 without any problems. I did this only because the 460's were just cleaned and two of the 550's were stuck partly open. I was running extremely rich after thesecondaries kicked on so I thought I would try this temporaily. turns out that with this setup I am not dumping fuel out my tailpipe and I haven't once run dangerously lean. Granted I am only running a AFR guage of a standard O2 sensor, but it does work well enough to give me an idea of the AFR.
