hi guys, wanna check, is it ok if i just fit in my 450cc injectors into my still NA 5sfe engine,

wld that be a good or bad idea.

i'm only swoping the injectors, cause i got them on ebay and want to test to see if they are working well.

Bad. You'll be running way rich all the time. You can try and take them out afterward.

yea, running rich, because even running as little fuel as they can, it's way too much for your car.

ok, thanx, so i can just plug them in, and check if they work, then pull them out again rite..

thanx guys for the running rich info.

sorry, another noob questions, how would i know if 1 of the injectors is faulty, would the engine fire up with 1 faulty injector?

^ It might

But you could put the new injectors in and then use something like a SAFC to control your air fuel mixture to make them closer to the same ratio

^ still saving up for my SAFC...

so i wun know if i had a faulty injector even if i tested it...
