Honda Car Forum

I'm looking for what fuel injectors off a stock car will fit a Honda civic. I need bigger ones but don't want to pay for expensive after market ones. I was told WRX ones will fit? Also RX7 will fit? Anybody know?

it depends on ur car and ur engine set up. Id suggest leaving the injectors alone jus give em a good cleaning. If u wantmore fuel get bigger throttle boddy and adjust ur cam so u can get a better fuel to air mixture. Them car like the Wrx and the Rx7 make their power by the turbos and how their programmed not the fuel. If i was you id get sum spoon parts from that web site in cally and u can get that thing moving.

How do you know you need bigger injectors? has the car been flow tested? If you put larger injectors in the engine without the proper fuel management then all you are going to do is run rich and get horrible gas mileage. The only way you will need larger injectors is if you have forced induction or a full motor high compression build.

what is the year and engine of the civic? How many cc/min are you looking to gain? I have a catalog I can look up some numbers for you if you would like. check out the web site below

DSM 440 injectors will work.
