sorry about the immature response.
the truth is the cold does affect, even with the heat back on the throttle body the afr still all over the place until the engine reaches operating temperature, before it would be all over the place until i shut the ignition of and back on.
OK now for the record, i replaced the DW550 (blue) injectors with new Bosch 550cc, i'm not making any reviews yet cause it's too soon but so far it's as perfect as it was stock even the fuel trims????...go figure


My Dad told me I should turn the other cheek... but keep my fist ready...

What are the most affordable and yet best for the money injectors for the 2013 Bk2 2.0t when looking to go Stage 3 custom but not with methanol or nitro? And are an AEM fuel pump and an AEM clutch 100% necessary? Thanks in advance.

RC racing 750cc are decent.

They don't state that they have any for the genesis, but the one's they state for the evox work. they don't have the extended injector nozzle like on the oem evox injectors
They don't have 550cc for the evox, because the evox injectors are already 550cc.
Might have to get denzo to bosche injector adaptors if you get these... or they might already include them. There's been people (other forums) that got the adaptors, and some not.


I believe the ones for the neon str4 work as well.

Yeah I just read that for being only at about 400rwhp that the 750 cc's should work just fine. Unfortunately my money is short thanks to buying a used BTR3 setup.

RC Fuel Injectors (Evo X) ? Modern Automotive Performance

These are still showing for $419, does anybody have these for somewhere in the 300's?

To add what I posted earlier.

The only time I used RC injectors are when I had my 280z with the stock L28E engine and then with a KA24de-t swap.
Ran quieter than the stock injectors on both. L28 injectors cost me about $300, and the KA24 injectors cost me about $260.
Don't remember what CC they were rated at, it was a long while ago.

Try looking up prices for the SRT4 versions of the injectors if you're still looking at RC injectors. Might be cheaper.

Thanks so much do they fit our cars or is an adapter needed? I'm new to researching injectors for the turbo swap I'm doing. and what size injectors are they 60mm or 48mm? Standard/Long/Compact? Thanks for the help in advance, I want to make sure I'm doing this right!

Looks like the srt4 injectors might be shorter than ours.

I have an extra set of oem injectors in the trunk. I'll get measurements and post them.

I was going to draw up a CAD rendering of the injectors, but solidworks keeps crashing on me.

Anyways, length is about 61mm from end to end (nozzle it recessed)

diameter is about 13.5mm

you can get away with injectors being within about 5mm longer.

There are NO aftermarket injectors that'll work on BK2 with the stock ECU. You have to have the stock injectors modified. Otherwise you have no choice but to go Haltech.

Who said anything about running larger injectors without a retune?

This is the BK1 section. BK2 ecu can be retuned to run larger injectors.

You can run larger injectors on a stock tune.... but it's going to either bog down, or flood the engine.

Injectors aren't sensors that can see how much fuel it's putting in, it can only see if it's completing a circuit when the ecu wants it to fire.

The person you're talking with lately has a BK2, only reason I mentioned it. I know it's the BK1 section, doesn't make a difference to me since he came here for help. Just don't want to see him waste his money. And trust me, no aftermarket injector will work on BK2 on the stock ECU, it simply will not even work, I know, I tried. I drove 8 hours one way to a dyno event and was going to be the first BK2 with aftermarket injectors, but they simply didn't work at all due to impedance. So yes, they're not sensors, that's pretty obvious but they also will not work.

You know, they make high impedance injectors.

You would have to find ones with the right dimensions.

diameter wouldn't be that hard to find, but matching length would be the issues. Most are a cm too long, but pretty sure you can just put spacers on the fuel rail bolts.

Sounds like someone didn't do their homework, before buying stuff. It says they're high impedance in the Fuel System - Engine Control System section of the shop manual

I absolutely know they make high impedance injectors, that's what BK1 injectors are... (12 ohm)

Size is 14mm in diameter and 60mm long for stock BK2, but doesn't matter since high impedance doesn't work.

Stock BK2 injectors are 6 ohm, no one makes them that I found. And the person that didn't do their homework? Yeah, we just assumed that BK2 used the same impedance injectors that 99% of other fuel injector cars used, you know, since I was the first one trying to do it after all, no one had done the work already... Anyways, only trying to help but apparently this has turned into a knowledge pissing match that I didn't sign up for. Good luck to the guy asking for larger injectors for his BK2 Stage 3 kit, only option is Haltech or modified stock.

Actually a majority of the cars made today run high impedance.

Reason it takes less amperage to run and runs the injectors cooler because of it.

Exactly what I said. Just Sadly not the case with BK2.

@huntken is correct. To date, nobody has figured out how to use aftermarket injectors with the OEM bk2 ecu. You have to switch to a Haltech to upgrade injectors on a BK2, period. I believe one of the vendors had drilled out stock BK2 injectors for sale, maybe BTR, and those flow a bit more than stock. To my knowledge that's your only option for the Bk2 at this time, but that's not good enough to run e85 if you want that. If you go Haltech then your BK2 will not have working air conditioning, so most people will not choose that option either.

Upgrading your turbo without owning a wideband is like skydiving with a blindfold

Ok yeah guys that was me with the bk2... So that means that the only aem injectors I could use would be going Haltech or having BTR modify a set correct?
