Rep Power: 349

I have the opportunity to buy some RC 440CC injectors from my friends RSX-S. He also has the stock ones that he's selling which as everyone knows is 330CC.

I have been talking with some people and they say that if I use the 440s I'll run into problems and especially detonation

I'd like people input as to what size injectors to use since I obviously don't want to wreck my engine.

Here is my setup:
SAFC II
TurboXS RFL BOV
TurboXS single boost controller
Turbonetics deltagate wastegate
Equal length manifold
T3 super 60 .48 trim turbo
Front mount intercooler
custom IC piping and downpipe
GReddy oil catch can

now the decision is between the injectors, but also if you have any recommendations please give me your input, I'm really new at this.

I don't even know what detonation means

i am now thinking about the GReddy emanage to control the larger injectors....anyone know what I'll need other then the box itself?

If you are gonna get the Greddy E-manage for your injectors, you will need the unit (the box) and If you are going to tune with it. You will need the extra Injector Harness if you want to mess wit your injector duty cycle. PLus if you are going to mess with your timing (retarding it) you will need the extra Ignition Harness that they sell with it. Both Harness's are like $35 so yea. I think 440cc should be fine. Not sure if they will fit tho. I know stock RSX injectors fit fine.

I'm pretty sure that the 440cc will fit the same as the stock ones.

So if I get the GReddy emenage, it'll JUST be those 2 extra parts with it right?

Yea those two other harnesses will be all you need to tune that stuff. Not to mention a good shop who is fluent in tuning the E-manage.
