my friend gave me some 440cc injectors cuz my injectors went bad from sitting for 2 years.. what will happen if i put these in my civic without a tune, my ls is stock except I/H/E... could this damage my motor... it already had gsr injectors on it b4 ran fine. idk if there same cc with ls or what ??? could someone let me know what could happen or if it will run like shiiit or something or do i need a bigger fuel pump..

thanks alot

 

oh my......stock injectors often last almost forever. Even if they get stuck a bit, this will sound funny, but i've hit them on the side with a wrench to free them up...it works.

btw, both LS and GSR injectors share the same oem flow rate of 240cc's

Running a 440cc injector on a stock car, and stock ecu program is overkill, and will loose performance in a major way

 

Unclog your stock injectors sell the RC 440CC's = Profit?

 

ill just save it for when i go lsv and i tryed uncloging them at a shop they said i needed new ones... idk so if i tune it would it be fine or is it still over kill?

 

that shop is not very good at what they do or something i would go to the junkayrd and get some injectors from a integra than and 440 injectors without a upgraded fuel pump would just still be overkill w/o a tune

 

You will not be able to use them not matter what. These are overkill for any engine Honda has and you will need a tuned ECU to utilize them.
