RC Engineering 310cc Injectors

I just contacted RC Engineering about getting some slightly larger flow injectors (310 cc/min) that are about a 10% increase from stock. The computer should be able to account for the increased flow with no issues. Thanks to Perfworks, I had the correct info when I called them and this is what I found out:

The injectors we need/have hold the following characteristics:

*They are saturated injectors NOT peak and hold.

*They have 14.5 Ohms of resistance

*Each injector is $85.65

*They will require a connector swap for $8.95 each injector

*RC has everything in-stock!

*If you call them know the make and model of your ride (no brainer....I hope)

According to the guy I talked to (John), I can get everything shipped ground for $387. Can you say CHACHIING!! I think it would be worth it.

Here are the price listings:

UPDATE!!! Juan at HiBoost (http://www.hiboost.com) has RC Engineering injectors (440cc)available for the Protege for $330 with spacers, connectors and all! What a deal!

What's pricing like on the MSP injectors?
What is the difference between the MSP ones and these RC ones?

 

[LinuxRacr]

MSP injectors are the same as the other Protege 2.0L injectors. They just have the advantage of better computer control for boost without a FMU.

 

[Kooldino]

That doesn't seem bad, BUT I plan on getting nice big injectors with the Microtech, which hopefully will be out soon.

The 310cc will be great. RC Engineering makes good stuff. Will you need to alter the injector pulse width to avoid running rich
when N/A?

I've bought a set of used 440cc RCE injectors and am awaiting delivery of a Pro-M Univer MAF and MAF Tuner to compensate for the increased flow. Supposed to be able to blow thru with this MAF, so I'm hoping it will be a bulletproof set up.


Linux have you got your JE pistons yet?

Accually the 310cc/min is about the limit your stock ECU can deal with without needing some type of fuel management. It is only about a 10% increase in flow. I expect my JE pistons today or tomorrow. Not here yet

Interesting...so you can use any sized injectors and just modify the MAS signals?

If you get too large, you have to have some type of fuel control. Think of it this way. The stock ECU can only control the pulse with to a certain degree. Add the increased flow of those injectors, and you start looking at atomization problems, and drops of fuel getting into the combustion chamber as opposed to the fine mist. This is the way I understand it.

I believe the MSP injectors are a little bigger. It was discussed in the thread about MSP ECU swap.

 

[Chojin]

Hey Everyone,

The MSP injectors and the MP3/P5 2.0L injectors are the SAME.

Cheers.

My bad, coulda swore someone said they were bigger

Folks say a lot of things. One thing we are gonna try to do more efficiently is find the right type of info, and put it out here. We are trying to kill speculation, and keep the facts straight. Shut up haters who come on our site, and tell us Protege people that we don't know what we are talking about. It's all good! We are here to learn....all of us!

to the first question no
440's ? i hope you will be running a greddy or some typeof management for injector pulsing
be careful with this MAF
i ran into some problems today with some bad news on the MAF's in the protege's
it seems they are having a hard time with changing the digital signal bieng sent to the ecu.
the majority of these MAF's are analog so i hope the set up you got will be correct.

no this is not true. you need to be able to control the pulsing signal sent from the ecu. the MAF will only show a broader range of operation so it does not "bottom out" on the voltage sent to the ecu from the increased air flow thru the meter

yes and dont forget the ecu CAN pull 30 % fuel but NOT at idle without it noticing a problem and going into limp mode. also upon acceleration it will "dump instead of pulsing it to the size that it can now handle.

there is alot of info out there now so be carefull and research before just posting. i ask more questions than i answer sometimes here and on other forums so i can get a good picture of how different systems work together to up performance.

 

[LinuxRacr]

Hmmm....I have a "not" where it is not supposed to be....Time for an edit.

So, if someone like "me" for example, bought bigger injectors, what would I get out of the deal? Another psi or something?

I'm just curious. That price isn't too bad. I guess I'll wait to see what we find out. But if I can supply the necessary pressure to the injectors I currently have, there isn't any benefit until I go to a higher boost. But doesn't this also mean that I would have to change the FMU to a lower pill in order to keep from being too rich with the bigger injectors?

Is the 10% increase worth it? Damn, now I'm confusing myself.
