I have a B16 swapped into a CRX Si with a PR3 ECU and have a couple of questions. From what I understand the injectors are peak/hold 240cc. I happen to have a set of saturated 550cc injectors here and am thinking about swappiung them out. Am I correct that the PR3 ECU will run saturated injectors if I remove the CRX resistor pack and solder the wires together? Also, what kind of fuel management is needed/recommended when going to 550cc injectors?

 

Anyone?

 

Too big, kinda useless.

But you can run them by removing the injector resistor box located on the driver's side firewall area. There's a power in wire, which splits off into 4 wires for each peak and hold injector. If you remove the injector resistor, just splice these all together into the main power wire.

Don't even think about running these without management.

Not really worth it IMO, unless you're boosting.

 

If you want some bigger injectors without all the trouble, get some OBD1 (310-345CC) Peak and Hold injectors.

 

Thanks for the info! The reason I want such big injectors is because I am going turbo down the road but I think I have a leaky injector right now but do not want to have to buy a set to use for just a short while. Any suggestions for management?
