Upgrading Fuel Injectors 1.8L R18 Civic 

Well I just finished putting my new ones in. I did everything the same was as you except for 2 things to make it easier. I removed the fuel line going into the rail (took 1 minute no tools required) and removed the entire rail with injectors attached and changed them out inside on my desk and put the rail back in with the new ones already installed in the rail.

I like your way of going at it . I'm all about leaving as much shit connected as I can lol. Hope mine all comes apart easily

Very helpful video bro, changed out my injectors by following this

Yes please tell the gains, i recently ordered 410 cc Rdx injectors and want to know what to expect

Kris over at Level Up Mechanics has a 35 Garrett he’s about to put in his 8th Gen R18a as well.

so the stock flow rated at 185 cc and upgraded to 310 cc without ecu tuning does it running rich and how about mpg or fuel consumption do they affected, sure consumption increased i wish to tell me not changed. also i need to know how to read the data stamped on keihen fuel injectors i have many removed from 2000's honda i want to use them in land rover but i don't know any information about the flow rate of them, this 185 cc or less is very good but how i know that i have them already..thanks

Bro, do you use the oem harness for the 310cc injectors?

The ECU will make the drivability adjustments for you over the period of a few days, so the higher cc’s only come into play at WOT.

Hi. Do you think my R18 can run 310cc fuel injectors without a specific tune? My car's ECU is remapped but not for 310cc. Do you think it's gonna have misfire, spark Knock or something?

Greetings I have a 2008 civic 1.8 that injectors SI from If I have to use that year

Where can I get 310 cc si injectors for my r18 I checked everywhere

Will this work for 2012 civic lx?

Can I plug and play ? 410cc without ecu touch ? Or better don't touch this ? (I bought chip-tuning)

what are the gains after this upgrade? I guess you also did remap the engine accordingly

do i have to tune after i change my injectors or do they adjust on its own. (like plug and play)...

How did the si injectors work for you? I’m planning on turbo with 410 or 450s

You put a 410cc injector on a stock r18 without any ecu tune? Why and what the gains are? Thanks in advance!

Do we gotta run 93 octane with these or will they be fine running regular

Did your car hesitate to accelerate when stepping on the gas.

what is the oem injector's flow rate please

Will these si injectors fit on my 2014 civic lx?

injector 310 from what car? 

what are the gains after this upgrade?

How did this mod do? Did you see better or worse gas mileage? More or less hp? Did you tune it or let the ecu work it out? Doesn’t seem turbocharged or supercharged? Just curious if the upgrade was worth it? Thanks in advance!

Saludos alguien que tenga esos inyectores en su R18 Vale la pena o el carro se nota alguna mejora?

I feel more dumb and have a headache.
