Do RDX injectors make power? 

Same goal with my z1!

Glad it was helpful!

Thank you!

i'll try and put that in a video when i can

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!

Thanks - I actually want to do a video on comparing intakes

they do, but their are bigger & better injectors that support E. these are good for NA setups imo.

Go 1000cc u won’t regret it save u time and money later down the road lol

Have you checked out some of my other videos? In my other RSX videos i go into more detail about the VTC angles

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.

@ I'm new in the Honda scene im on old vw guy. I recently bought a 08 si K20 Z3 6 speed manual has a well penis intake and Honda with flash pro. Trying to get it to at least 250 275 without spending too much. What do you recommend? Really appreciate the info.🙏

@@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.

Nitrous.and tune Cheap and safe as hell on a nice tune

Aaron Millar I made 265whp on those

@@mcmastersnick with just bolt ons and this setup in vid??? So it's a better choice to go decapped stock vs stock capped or rdx 410s?

The Dude no, I had drag cartel drop in cams and a k24/k20 setup. Bigger injectors aren’t going to do anything for you unless you’ve got mods that require more fuel.

@@mcmastersnick what duty do the de capped stock injectors run at that bhp?

Yes I do - its best to send me an email and we can discuss - nick@tuningbynick.com

jonny francais - Stock oil pump and VTC gear. Yes I am running an RBC intake manifold. Check out some of my other RSX videos. I go into detail of the whole car

This is a great comment - Exactly what i was trying to get at in this video. To try and not focus on the peak numbers. The important part is the before and after results

Because this is my personal car that i really only use for testing ive set the redline at 8000 and i was taking it to 8200 on the dyno. Normally i dont recommend over 7800 for clients K24 if it has the stock oil pump

most likely overall temperature, those crackle tunes rarely do any damage to your exhaust valves and if it does it takes a LONG time. also another thing i do know is that these tunes don’t take away from performance

5 to 10 hp at this power level, but more and more if i added more parts to help make more power

This is actually the cheap stick on universal lip you can get on amazon or ebay - Its super easy to do and looks good on these cars

I would personally go with the IDs over the RCs - At the bare minimum you should upgrade the pump

@@tuningbynick okay. Can you also tune JRSC, on a k20. After I figure out what's wrong with it first. Might have a big vacuum leak somewhere, because when I block off the TB with my hand, the car hesitates a bit, but it kept on running.

Rc750cc

Thanks! - Jeff Evans offers paid course you can watch to learn all sorts of different systems. i hear they are very good

@@tuningbynick Thank you, I'll look into it.

Thats odd, i had no issues like that - Maybe its how the engine mounts sit - i am using Innovative mounts

Thanks ya I’m on stock mounts, and got hood to close had to shave some off the hood

Sometimes older tunes cant be downloaded with the newer versions of the Kmanager software - Its best to contact the tuner and get the original copy of the tune

You wont see much of a gain without getting Into the tune. The increase you're looking for isnt going to happen just dropping in another stock cam without any tuning.

Joe Dooley how much difference in hp would a drop in drag cartel get vs stock cams. Obviously with a tune now. Not going with tsx but either prc or k20z1. Again trying to gauge the best $ per hp route.

I would run RDX injectors

those injectors would not be big enough to run E85

Yes to both of those.

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

@@tuningbynick thanks for the tips. Because I will be doing a Budget build I will be the one adjusting parameters. I’m new at this but have been doing a lot of research. We will see how it goes. I started off running afr flow but some tuner in Germany advised me to adjust AFM fuel not flow to adjust fuel trims. With 5-8 psi on 410 cc I’ll be around 70% duty. Also looking at DW 450s

Thanks! - I honestly cant take the credit tho, i bought the car with them, as soon as i get a chance i will pull one off and verify the size

unfortunately i dont have any experience with decapped stock injectors

Taking the filters out will give u more power for sure 👍

Taking the filters out will give u more power for sure 👍

@@Fa5Squad how👀

@@bryce_fa5si theres little filters inside the injectors taking them out increases the flow to like 650cc but just better off buying bigger ones

Both are good choices - I would really discuss directly with your tuner tho

RDX are too small for E85 and FBO

The parts wont work properly if you just put them in - You'd need to get the ECU tuned to work properly with the different parts. Since its just for fun till your other engine is ready, its probably not worth the hassle to do it

@@tuningbynick I did forget to mention I do have the kprov4. I should of been more clear my mistake

2006 K24A2

ya thay can

basically the same process - just change the injector size and the dead times

@@tuningbynick the dead time given within ktuner when you select rdx injectors are they any good ? Or I should use different figures ?

Yes i am - in Toronto

Im in Toronto, so not at altitude

I have orders some parts for the swap, they are going to take awhile to get here unfortunately

@@tuningbynick wait people are doing DSG gearbox swaps in these things now? Like as in an auto? Or am I misunderstanding?

@@muaminhugsy4964 i think that's a joke

@@jorgerebello8238 I just checked some previous uploads and apparently its something nick is trying to do, would be mint

I would say yes, the stock injectors are a bit small

This is on Kpro

yes - non insulated then protected with adhesive heat shrink

@@tuningbynick i saw the heatshrink. I just wanted to know exactly what they are called. Im getting ready to order some. Thanks for the response. Is there a particular brand you like more than others?

Its still a stock returnless fuel system on this car

Its not .. i rev to 9k all day

8k is the limit for tsx pump. K20 oil pump good to 9k or so

@@oscarescobar2777 You def dont re a stock k24 to 9k all day lol

@ as far as stock rsx oil pump 9k is my limit ... stock k24 i definately wouldnt take it to 9k ... mine is k24/20 and built a bit and i do take it to 9k all day

@@oscarescobar2777 well yeah no shit you can take a built frank to 9k... THis aint a frank tho my man.. The original comment is talking about the stock K24 oil pump.. The motor in the video is a K24, not a frank..

Yes i am - I should have the final part ive been waiting for this week

Im in Toronto - shoot me an email if are interested in any dyno tuning or if youre far i can do remote tuning

Yeah I am far how can that work ? Remote tuning

In a perfect world the size of injector shouldnt matter - But older injectors had really terrible spray patterns. I have a set of 1000cc injectors as well and will be doing a similar video with them as well

@@tuningbynick awesome! cant wait to check it out.

Only soo much air and timing you can get from an n/a engine. While the injectors aren't maxed out, other parameters may be

@@Darylrb1983 I ran a k24a2 N/a with a 72mm TB, straight pipe, RDX injectors, 255lph pump. Sold the car before I went bigger on injectors but had a ton of more room because when I started really dialing it in I just kept running out of fuel.

shoot me an email and we can discuss - nick@tuningbynick.com

Just found it! Disregard haha

for sure - shoot me an email to set something up - nick@tuningbynick.com
