i have a B16A2 civic vti (equal to 99-00 si)

I purchased 440 cc injectors from precision but I don't know if they are going to work without a resistor box. how do I find out if they are low or high impedance and how do I know what impedance I need them?
also, I have problems trying to put them in the holes where the old injectors used to be. the old rubber gasket doesn't seem to fit the new injectors. it seems to be too narrow. should I try to cut a bigger hole in the gasket from the inside to make it fit or should I get new ones? if yes, what kind of gaskets? and do I need any gaskets with these injectors at all?
if i put in a gasket the injectors would sit higher... does the height of the injectors matter?

thanks

 

you should be able to put the precision injector in the hole wihtout the gaket the 440cc you got is definitely a high imp injector no wiring needed.yuo can veify by taking and ohm meter across the two points

 

oh, here are some pics of the old and new injectors:

 

thanks b18, I will do this.

 

i took the ohm meter and the result was:

old injectors: 11.5 OHM
new injectors: 15.7 OHM

does this mean I need the resistor box?

 

No you don't need a resistor box because its high impedence.

Also your gonna need to take the sanding drum of a dremel tool and make that rubber gasket bigger. (The same thing that people do when using DSM injectors)

yeah I read about people doing this with DSM injectors.

however, the DSM as well as the RC injectors don't have the integrated rubber seal as my injectors do:



maybe I don't need the old gasket at all... what do u think?

 

dont need the old gaskets and all just put them straight into the rail you should be fine it will not leak

 

These are high impedance injectors.
