I am replacing my fuel injectors withen the next week to get my car on the road but i dont want my fuel injectors getting screwed up again if the regulator is bad because the injectors were not exacly cheap. I would like info on what fuel pressure regulator i should go with cheap and good quality would be nice. 86 rx7 1.3L non-turbo. thank you

 

...? stock one is fine, they don't fail that often and there are plenty of good ones around. there's no reason to replace it on an n/a.

 

Is there any way to test the one on there justin case?

 

yes, with a fuel pressure gauge.

as stated before, it probably doesn't need to be replaced.
