It would benefit from a 50 degree gear because of the new k20 RBC manifold. Some k24’s even lose power with an RBC compared to the stock manifold without a 50 degree VTC. Great video! Thanks for sharing!
What’s up guys so I was always scared to through on a rbc cause of your comment lol I thought it was gonna be the waste of the 400$ for a rbc I paid 230 lol but anyways I had got dyno tuned with just exhaust header and cai I made 213hp with 168 tq (greddy 2.36) exhaust and a dtr header, I went back to my tuner with a hks 65mm and a skunk 2 header and that rbc with a spacer to still use my stock throttle body, I ended up getting all that retuned and made 227hp with 185tq similar to what this guy made I just made about 10 tq more, so pretty much saying in my case the rbc did a lot for me , I made a bunch of more torque just cause of that , and during the tune we did a run to see how much I was making with the rbc untuned I made 220 right off the back, so you do make a tiny bit of power without tuning it but once you tune it you gain a bit more and a lot of more torque so getting it tuned helps a lot!!
just deserved yaself another sub. i have a 02 rsx base with a 08 k24a2 with a unknown header and RBC aswell and i been street tuning my k24 for a good 2 months now off and on because i sometimes catch my a/f get wonky sometimes lol im glad i came across this video. can you possibly do a detail visual video on cam angles in kpro whenever you may have the chance?
Hi Nick, Just out of curiosity.. Did you measure difference between k24 and k20 oil pump on k24a2/3 engine? I would like to know ho much power can hold balance shafts. Thank you in advance for your answer!
Awesome vid nick. If you could in the near future before you go awd and turbo, plz do upload the 50 degrees VTC cam gear comparison with your current 227 hp stock setup. Keep up your good work and thank you.
Tuning by Nick awesome brother. Looking forward to it. By the way it’s odd your RSX made more power in stock form than the ep3 k24A you tunes and dynoed. Just found that odd that’s all.
Hey Nick, loving your videos! I have a k20 type R swapped mr2 spyder. But also have a k24 in the garage. I was always planning a K20/24 build. But is it really worth the hassle of assembling a K20/24 frank or should I just put in the k24 with 50* vtc and type R oil pump and call it a day? Will keeping the k20 head with the k20 cams give me that much of an advantage, of at all?
So what do I need to do same swap to my 05 type s ? 06-08 tsx or jdm k24, and a kTuner? Do I need other mounts or parts to make this swap work ? I have a z1 now but might be looking for upgrade
Did you use the stock oil pump or did you use a k20 oil pump with the balance shaft delete? Nice combo will hit you up when I get my k24 type r up and running ivd got a basemap 👍
I've seen 2002-2004's in decent shape for around 3K, I'm thinking of grabbing one and throwing in a K24/K20. Checkout his guys build ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Cv4NjiG_rug.html I'm not sure how but he's making over 220 torque with stock motor just cams.
Have you done any testing with the stock tsx intake manifold vs the RBC? Hondata shows a loss in tq but your graph looks awesome. I'm doing this swap and trying to decide if its worth adding the RBC, thanks!
Aren’t you supposed to swap over type S oil pump & plug an oiling cavity under the windage tray to avoid loss of oil pressure and cavitation at higher rpm?
The higher angles increase overlap and help with scavenging until very high rpm where the cam angles may want to be retarded to take advantage of the air inertia and the ram air effect. If this was a turbo application I would expect less cam advance in the mid range due to backpressure from the exhaust system. The k24 and k20 share almost the same bore only the k24 has a longer stroke making it undersquare. The k20 may rev higher but the peak torque figure would be less. The k24 may make more torque but at a lower rpm. Thus, both engines can have roughly the same hp but their torque figures can be quite different. If the k24 made its peak torque at the same rpm as the k20, the k24 would make more power mathematically. However the K24 being undersquare, limits the maximum rpm lower than that of the k20. Also, the K24 head is designed to be most efficient and operate at a lower rpm, thus any larger increase in rpm may net a decrease in torque. If you can safely get the k24 to rev like the k20 then fitting a k20 head to the k24 may be beneficial.
you prolly dont give a shit but does anyone know a tool to get back into an Instagram account..? I was stupid lost my login password. I love any tips you can give me.
@Hugh Zev i really appreciate your reply. I found the site thru google and im in the hacking process now. Looks like it's gonna take a while so I will reply here later with my results.
Matthew Trudeau - I technically didn’t do the work. But as far as I know. The only change was swapping the shift selector in the trans from the Civic Si one to the RSX one.
I dont personally do much install work these days but i'll see what i can do. In the meantime. Check out my friends channel - Speed Academy - They have great video on that - Heres the link ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-txvwWJmxB3U.html
There been videos by other people on this, short story is a k24/20 Frankenstein motor is not worth the extra 30 whp or so if you plan on building the engine/ boosting.
@@TienTran-kw3il Where can I find those videos? I can't see 30 WHP just from swapping a K24A2 head for a K20A2 head, that's about the gain you'd get from swapping a VTEC-E head to a true VTEC head such as a K20A3 to K20A2 head swap.
The only change to the harness was repin the crank sensor because the pinout is different. I actually had an 8th gen Civic Si LSD transmission in the car at that time
Do you know the specs of the "jdm" k24a motor? My local shop is having a sale and im thinking of picking it up. And also, would the skunk2 alpha header fit on the k24s? thanks!
The Skunk2 header fits - But because the K24 engine is taller, it raises the header up higher and it hits the front sway bar. I had to completely remove my front sway bar for now. Unfortunately i dont really know anything about the JDM K24A
Thank you for giving all this info. I know it's a year later, but do you have a teat run on the 30 degrees? So we can see the difference. Thank you again for all the tests and info. Peac n love my man.
I spent hours trying to search info for a K24 build. Ive found the highest output "OEM" build is based on the following: 06-08 K24A2 block K20A2 Head 06-08 TSX cams RSX Type-S cam gear Type-S oil pump Type-S oil pan I scoured multiple forums for this info and this has been upheld by a majority consensus. Hope this helps anyone looking for direct answers like I was.
You can use a A2 or Z1 head. They're the same cast, the Z1 has the better cams, but it's been noted, as you wrote, that the TSX cams in either of those heads produces about an additional 10hp over the A2 cams, maybe 5hp over the Z1 cams.
Did you do anything to the thermostat housing? The tsx faces up and rsx s is down. Just wondering, I'm doing a k24 build on the rsx to but I'm stuck on that
Hey I just put in 07 tsx motor in my type s, similar bolt ons like yours but the next step is for me to just swap out the type s ecu and get kpro v3/v4 or Ktunner, any big differences between these ecus?
The TSX head is nearly as good as the K20 Head - At this power level the K20 head wont actually make any real difference - The expense of the K20 head would not be worth the minimal if any HP gains over the TSX head
Does anyone know how the 06-08 TSX cams compare to the JDM K24A cams? Is it worth spending 300 bucks on used cams. Is the increase in power even negligible?
Marcellino Munsami my k20a2 with RBC 4-1 manifold and 2.5 inch system pulled 221 WHP.. the k24 has a lot more it can gain in an NA form just from a K20 head or VTC gear with better cams!
What’s up bro I got a rsx base I was planning on swapping it to k24 but does it matter which one I get? There’s one from crv and one from tsx I think and does year matter ?
K24 > K20. The K20 is better suited for boost with a higher redline , less compression and make more top end on boost due to a better flowing head however the K24 on boost is better balanced between torque and horsepower if you want more torque.
@@josiahbutler2254 yeah it’s good numbers . The dyno reads hp to the wheels so if we’re talking about crank hp that dealers use to advertise their cars, 200 hp from the stock tsx to around 255-260 hp (227 hp to the wheels) is very good for basic bolt ons and a tune. 40-50 hp gain from those small things and a tune is what makes the k series engines great
Now put the K20 head on. The TSX head Vtec sux. And low redline. If you want more torque and not lose Vtec but have the best of both put the K20 head on the k24 block and your running a monster bottom end with a monster top end! ..Do It!
JoWaY - I sold the whole K20 engine. TSX heads are not bad. They flow nearly as much as the K20 head. The lower redline is because of the rod stroke ratio. Not any limitations of the head.
I'd say it would benefit from 30~32 ° VTC . Usually if a K sees an increase at the max stock 25° it will benefit from the 50° gear. I've had a K lay down the 250's @7800 @ 35° VTC
Chase Kephart - Typically a stock TSX engine cant benefit from VTC set that high. But there are always exceptions. If I can find some time I’ll be installing a 50° wheel, retune it and do another video for everyone with the results
@@tuningbynick I've tuned several and they benefit, but it depends on the exhaust side of things. They all been free flowing exhausts. 9th gens definitely do not benefit from it. Normally I set vtc to 45 then test lower or higher.
K24 usable power isn't very impressive coming in right at redline. That K24 needs to be able to spin out another ~1,000 RPM to shift into your power zone.
