I have a 94 Civic EX with a T3/T4 turbo (6 PSI on street and approx. 10-12 PSI at the track) and am not sure what type of RC injectors I should be using. Do I want to use the Peak and Hold Low resistance 2.5/3 ohm injectors or the Saturated High Resistance 12-16 ohm ones? Also, is 550cc injectors ok or is that too big/small? Thank you for any help I can get!

 

I'd go with 680 cc. Just to be safe. Its probably only another $40. And look into Precision injectors. They're a better injector than RCs in my opinion.

 

You'll probably get a better response to this in the forced induction forums. Personally I think the 550's are big enough for what you're doing.

This may or may not help you out, but here you go anyway, I think its a nice little tool.

ITS A SOHC CAM MOTOR.....i would say 440's are perfect, I ran 440's with more boost than that before, and for the type just use the high resistance ones, pretty sure you got to get different injector clips too.

 

Thank you for the advice, but I still don't know if I need to get the Low or High Resistance injectors, any input on this?

ok, thanks! When you buy the injectors do they come with the clips you're talking about?

 

No......dont ask me where I got mine because the car allready had them on it when I bought it.

 

Yeah you need the saturated injectors..To use the peak and hold you would have to wire in a resistor box..How much HP do you want to make..?? HAve you ever though about maybe some dsm 450cc injectors..? You can get them things for like $50 all the time..

 

Yeah forget the 670cc. I forgot it was a SOHC. DSM injectors are direct install and cheap.

Direct install minus the resistor box.

 

Thank you guys for all the help. I'm going to just go with some low cost 440cc High Resistance injectors for now because I just bought a Sleeved block this morning. Hopefully by mid summer it will be ready to go and I'll be boosting 20-25psi. Any idea what size I'll need in the future?
