Very good video, thanks!

The K20 already has good injectors to start with, multi hole with a good spray pattern, so it wouldn't make more power with RDX injectors, you just have more headroom for power. This test would be interesting when replacing old tech injectors, like for example B series injectors or 00-05 S2000 injectors, with these.

@tuningbynick

Thanks - I dont think so, i am running extremely aggressive ignition on this engine already. The main benefit to these injectors in my opinion is they allow about 20-30% more fuel flow which allows you to make more power if you are close to maxing out the stock injectors

​@@tuningbynick Does decapping help stock injectors or does it just ruin the atomization? Thanks!

Perfect man!!!!!!

I guess the only reason you would want to change is if the injectors were holding you back. Seems pretty obvious if you are balancing air and fuel it would be the same. Same amount of air its just easier for the rdx to do the same thing.

Nice vid, you would se BIG gains if you swap the k20 head out of the k20z1 (completely) to your your k24 block about 15-20 whp minimum...

Do one with the stock k series injectors with the caps removed.

@Tuning by Nick Just did RDX injectors and noticed how short they are. I had the manifold off and saw that the injectors sit about a 1/4 inch up into the hole. Almost like it's shooting the fuel threw a straw. Would like to see this test with intake ported down, so the injectors sit flush in the runner.

This video was so helpful! Wondering now if these injectors could handle e85 on a k20a2. I guess I will find out!

He wont need a ported oil pump unless he is doing serious NA building.. 9K is MORE than enough even for a frank build. And reliability would be hugely compromised with a k24 bottom end at 9K+ rpm.. 9krpm on a K24 is the equivalent of over 10K rpm on a K20.. At least in terms of piston speed.. He would need a fully built motor. The stock k20 oil pumo is perfectly fine to 9K.. I had a built frank making 290whp that revved to 9100 rpm and that thing lasted for over 3 years being beat on constantly with the stock k20 pump. RDX injectors are overrated.. For around the same price you can get a set of ID725's that have(in my opinion) better spray pattern and are tested more for performance and have more capability to for more power.. RDX injectors are only good for a super small rev and power range over stock injectors.. You may net a few HP with full bolt ons on a K20 with a higher rev limit or a built head, but if you build the k20 at all with cams, valvetrain, and pistons, they are limited. So it makes no sense to spend $350 on RDX injectors for a few HP but still have an injector that cant make 300whp.

@@PeterFeltersnatch852 To go 250+ Naturally aspirated is gonna cost money.. You'll need cams, port-match intake with 70+mm Throttle Body, a good 3+ inch Cold Air intake. You will need a good race header and at the very least a 2.5 inch full exhaust. With that, you can probably make about 250-260 tops depending on the cam you go with, but reliability does become an issue with more timing and cams. In my honest opinion, Id look for a used Greddy Turbo kit, or a nice SuperCharger.. MercRacing makes a PHENOMENAL kit, but is expensive. But what makes going boost more practical is 1, you have more versatility to make more power, 2, you can stay bone stock without needing more RPM and more timing, which keeps reliability up.. If you stay below like 11 PSI of boost, you will be perfectly fine and reliable. If you go with full bolt ons without cams, you can probably make about 230whp, but the K20 motors are so slow below 6000rpm when they are Naturally aspirated. I personally went K24 in my RSX Type S and it made a significant difference as it has more torque and more power at lower RPM. If you want to save some money, just go with a custom turbo kit. You can get away with an Ebay turbo for cheap, just have it balances and checked at a machine shop before install. Just make sure you dont cheap out on the technical stuff that is crucial for operation, like injectors, intercooler, wastegate, BOV, map sensor, fuel system.. Humble Performance has a FANTASTIC turbo kit for like $3,000 ready to go with a Precision 5858 Turbo. Its a 500-600whp kit but you can run low boost and make 300-350 quite easily.

I see your actual AFR and AFR Command are not always the same. Why is that? (Mine does the same thing) 3. Any issues with tuning authentic RDX 410cc? 2 tuners told me to go with DW injectors because these are hard to tune.

Hi - For your questions 1 - You would need to adjust the AFM Flow table 2 - The actual AFR reads will fluctuate based on what youre doing with the gas pedal and or if youre transitioning between low load to high load - You can really only expect them to be the same or close under state state load conditions - When tuning we are trying to get those actual readings as close to the target/command under steady state conditions 3 - Real deal RDX injectors work well - But if youre going boost they are on the small side - Ive tuned hundreds of sets of RDX with no issues As for your turbo project - i am always happy to answer questions - but my honest recommendation is always to find a good local tuner to work closely with so you dont get conflicting answers to your questions - We all like to do things differently
