Would 550cc Injectors be too big, or is it like everything else, nothing is too big

 

Many people on this board and m.net use them with various EMS.

 

There is such a thing as "too big" when it comes to injectors- rough idle and increased emissions.

550cc ought to be good for around 270 HP or so. Quite a few folks are running them 'round these parts. 440 and 460cc are the next common sizes down, and perfectly adequate for most sane Miata applications.

 

I run 550cc RC injectors. Its all in the tuning.

 

I don't have them installed yet but i got my RX7 550cc injectors for $150 after cleaning and servicing at cleaninjectors.com.

 

I mean I wont be running 270 hp, but it would be nice to have bigger injectors incase I were to build my engine and get an upgraded transmission :-D haha

Those injectors with the MSPnP should do well and not have that bad of an idle?

89-91 RX7 550cc are direct plug in?

 

if you can afford to build your engine and transmission, you can afford bigger injectors when you need them.... right?

 

It would just be eaiser to get injectors that are more inline with the power you'd be running.

 

I would like to run around 220. What would be a good injector for that?

 

440 or 460
