you need a different rail thats for sure, but I dont know if the GTi-R Rail will work on a SR20DE. I may be wrong though, you can't use the stock rail though because thats for sidemount injectors, and the 444cc's are topfed. So what I did was I just bought a new rail from JGY for topfed injectors.

Wire the resistors into the the injector signal wires by the ECU, that way your engine bay will look better that way.

the injectors are too small to fit in the jgy fuel rail its made for 50lb and 72lb msd

lemme ask this, will the 444cc need resistors? I am looking to get a set w/rail and need to know. Also do they fit fine on the intake? And I imagine I would need the clips.

This is one of those hard to search subjects, has been asked many times and there's no sticky for it :/

yes they will because they are low impedance. the car will run without them but will run very rich. u need four 6.8ohm 10watt resistors. you put them on them on the signal wire for the injectors u can also put it on the power side if u want.

Hopefully, I will be done by the end of the year.

How do Know which wires are the injector wires that go to the ecu? And will the stock injectors wire conectors/clips work on the 444cc injectors?

Aight I spoke to someone and found out that you wire the resisitors into the negative injector wires. I have the gtir clips for the gtir injectors and they all have different colored wires but all 4 clips have one thick wire and one skinny wire. Which one is the negative wire?

Aight I figured out that the skinny wire is the ground for each injector set.

Just solder the resistors inline to the negative wire on the injectors. JWT had a write up on how to do this properly and I used it for my gti-r injector install but I can't find it so here are some of my install pix..
