RX7 injectors

[S13Ka24e]

I have hear on some threads that RX7 TII injectors are top-feed injectors and fit the ka24e. Is this true? Should I just go to a junkyard and find them? Does the TII have 2 or 4 of these injectors? They are 550cc? Thanks, I'm going to use either greddy e-manage or AFC to control them.

They are top feed. As for fit I am 99 percent sure they will work. They have 4 but you need to remove the intake manifold to get the lower 2. TII are 500cc...I will be your best friend if you EVER find a TII with a motor in the Junkyard.

Also I hear the AFC licks balls.

Hope any of this works...

I will be your second best friend if you find the motor.

Any one for thirdsies? But anywas, do you think that you will be able to save money by doing this and buying used injectors rather than going through an aftermarket supplier and possibly going larger?

I like getting my injectors from RC. You never can tell how used injectors are going to run. If they were in my car chances are they spent most of there life pumping fuel at there max duty cycle and there about to crap themselves.

I would recommend buying new ones and having them flow tested. Then stick the one that flows the most in cylinder #4 and work your way towards #1, with the #1 flowing the least.

just got a set back from RC, good service. I'll be sending them 12 GT-R injectors to clean and flow test for me. If you are going to use used injectors I highly reccomend this be done before you use them

Why does the flow system work like that WD, with #1 having the least?

[WDRacing]

#4 is the hottest cylinder, so it should get the richest flowing injector. Everyone does this on I6's so I figure the same should apply to I4's.

It has to do with the coolant and oil temps as well as the pressure to the rear cylinders. Its just a little somthing for added safety.
