I wish I would’ve known this information about Honda engines 15-20 years ago. I remember just aimlessly buying parts because that’s what people would tell me that’s what I needed without any solid evidence of why. Honda’s V-tech engines were incredibly well engineered
One of the reasons I absolutely love the k20 is that it truly sounds good. Most 4 cylinders with the exhaust completely removed would sound like a brappy mess but the k20 actually sounds like a race engine
Amazing step by step experiment with bonus dyno graph comparisons of other setups, this information is so key not just for RSX but for the K series engines in general. I wonder how a fully built K series with forged internals revving to 9.5k would compare, I saved a video of it somewhere.
thankful for no salt in Oklahoma, I just bought a 180k mile 06 RSX-S that is also completely stock. put it on a lift and there is zero rust on the car and even the exhaust hardware isn't corroded.
Love these k20 Videos. Also shows you dont need to spend a bunch for bolt ons. Just get some cheap ones and a tune and you will be probably 80-90% of what the expensive parts are
Great content ! For k20z1 I would imagine the end result should be very similar maybe slightly higher power in each case ? If could also include 100cell high flow cat testing would be even better 👍
Siiiiiiickk!!!!!!! 👏👏👏👍. I would love to see more of these k series tests with different bolt on mods. My jdm k24a made 228hp 196tq. Springs/retainers, 4piston oil pump, ktuned kswap ram headers, speedfactory 3”exhaust, vibrant muffler,lightweight flywheel. Still has the stock k24 intake so I’m very curious what just an intake swap would do.
@@Without_Limit_Auto good idea 👍. That is really what I wanna do that’s why I got the k24a first then thought I’d just get the k20 head later but now it’s hard to find one in decent shape locally. It’s my first time with k series so I’m learning.
I really like your contain and i follow it in the name of science i like it ! What i think that could let your power similar after removing cat converter is : #1 this is not a oem cat converter ! Oem cat converter as the 2-1 split continuity so this would may have help to make a little more scavenging effect! #2 no more o2 sensor connected could have possibly bring the ecu to weird fuel trim etc .... But that very cool contain again sir :)
The k series engines with intake an exhaust valve vtec k20a2 and k24a2 have 30whp more than the 9th gen si and ilx, my 2019 ilx is 160 and 158 weighs 300lbs more , ouch
Curious to know how your Dynojet 224xLC Load Control Dyno compares to a Mainline dynolog 2WD600L chassis dyno that I have been too (correction 17.8 SAE J607) my j35Y1 put down 225.2Hp and 186.5 ftlb (SRI, PCD, MD, 94octane, Ktuner). What do you think it would put down on your dyno? asking so I can gauge how a k20a2 stacks up?
How did u get the AFR readings with open header? Do u have a sniffer or was it just a blind run with a known good basemap? Thank you for this great vid!
Would the results for a k20z1 be similar or different. I have heard tuners squeeze out more power out of the a2 even though z1 technically has better cams and final drive
earned a subscriber for putting this video out in the first place, nobody is making content this thorough on the DC5. Incredible

what does the "h" stand for?

Sick vid!!!! Now people gonna run around with no air box and open exhaust lmao
Haha
Oops secrets out

Great content Nick! A 2L NA picking up 19hp 14tq is really really impressive!
Learned a lot from this video thx Nick
Great video. I appreciate the concept behind it. Reminds me of the days when I used to read about this sort of stuff on Sport Compact Car Magazine.
Yes! And Import Tuner (the Power Pages section).
Thanks for the ECU Nick! The brains from this beauty will live on in my rsx.
Really cool to see the comparison of everything. Shows you where to spend your money
Love these types of videos do more please !!
Thanks for the vid Nick, I love when tuners show us dyno results in stages 👏🏾👏🏾
I like these kind of experiments very informative, thank you Nick!
Its the video we all wanted to see, but didnt received until now!!! Thanks for the research!!!
This is very good Content. Thanks a lot for showing the gains.
Love these k20

Great comparison as always. I'd love to see a comparison between a k24 and a k24/k20. Curious what the top end differences are.
Glad I live in southern BC with almost no snow.
Thank you so much for the sharing. Your video saves us lots of time and efforts
Amazing content as always)
The crazy thing is you picked up all the gains of the FBO without spending a dime, the extra hp up top is past 8k and not very usable.

You need k20 head with some good camshafts

@@Michael-kv2im got ya. I already have 3 K series motors. K24K20 NA 350 HP, stock K20 230 HP and turbo K20 around 700. But I haven't built by myself.
Great video and test! Interesting how much skunk2 intake manifold gives and also it's better to grab cold air into intake, not how it was

Can you do a comparison with the stock intake box? Id like to see the air temp and power difference
I just bought my first rsx type s
Love these videos! How do you like the DC 2.2 with a K24a? Does it see similar gains as when compared to an internally stock k20a2?
Good stuff Nick, if you sell interior, I'm in need of rear seats plz
I remember you dyno’d a ihe jdm k24a with 245whp.
💯👍
What is the afr after everything was removed?
The k series engines with intake an exhaust valve vtec k20a2 and k24a2 have 30whp more than the 9th gen si and ilx, my 2019 ilx is 160 and 158 weighs 300lbs more , ouch
Love the videos. Have you tuned a nitrous k-series before?
Cant wait till I put in my kraftwerks and get you to re tune !!!!
Sick dude where do you located I wanted to retune my rsx type s
Grt work, grt 👍👍👍👍👍💯💯💯💯
Do you sell any tunes/ maps? I have a full bolt on rsx 05 type s.
Did you ever tune RSX k20z1 only with Intake injen and exhaust catback on kpro? Or did you try same testing like this on k20z1?
Have you noticed any changes in powerband from different headers with different cylinder pairing on the primaries?
I've seen that car before! 😄
Poor decision, you really should be fixed it.. dc5 chassis is timeless... I would understand your decision if you got it for under 2k
Nice

Use 98 octanes?
Threw a k-pro in the car and already makes more than a z7 lol
8:53 weight reduction!

no shade but snow tires on the front and not the rear..... smh....
Aftermarket cat
Did that guy even need rdx injectors? Was he running out of fuel or do people not get how injectors work?
