looking to buy replacement injectors for my 88 na wondering if anyone could send me a link on where to buy them cant find any that look reputable.

 

welcome to the board.

have you checked with places like Mazdatrix, RB or Atkins?

have you looked into having yours rebuilt (WitchHunter, Marren, etc.)?

 

Rockauto has them as well 1988 MAZDA RX-7 1.3L R2 Fuel Injector | RockAuto
I used a GB Manufacturing on my truck last year. So far so good.

 

Be careful with this. The picture rock auto has for the GB manufacturing is a low impedance injector. 87.5-88 cars used high impedance. If you run low imp injectors on a car meant for high imp, you'll fry the injectors and the ECU.

To visually tell the difference for S4 injectors, the low imps have a centered keyway. The high imps have an offset keyway

 

I was in a similar situation, old ones didn’t have a good output and they were all junk, bought a set from five 0 motorsports and they were junk aswell, I would not recommend. After they wouldn’t start my engine because it kept flooding I checked them out and the cap that the needle sits in cracked by just putting it into the oring and taking it out. Sent them off to get cleaned and they were all over the place and the part numbers were scratched off and I never realized. I thankfully found a used set from rx7 owners club on Facebook sent them to get cleaned at injector rx and they are perfect. Haven’t been able to find any new decent oem cc flow injectors for the life of me. Good luck.

 

What all is done to the car? stock?

 

I just bought brand new injectors but they were god awfully expensive. Make a post in the market and hawk eBay usually whatever you need will show up before long.

 

I had my stock injectors rebuilt and they worked fine. I started having flooding problems at about 20k miles on my Atkins rebuilt engine and thought that the injectors were leaking again. Turns out that the injectors were still fine and the flooding was caused by low compression not leaking injectors. So I recommend sending yours out for rebuilding and testing!
