K20 Tech Inspection

[@garrettrinquest1605]

Would love to see this for a K24. Especially if it included info on what transmissions to use and how to find them

[@dde6127]

Like the comment guys

[@Givelasagna]

K24a2 or the equivalent jdm spec k24a are the best ones you can get. They have the 3 lobe vtec on both intake and exhaust camshafts and have "true" vtec. Mate on an ep3 si 5 speed or tsx 6 speed and you pretty much have the best combo.

[@EduardoISF]

Best thing you can do is buy the cheapest k24 out there. That extra money you’re saving from the others do yourself a favor and just buy pistons and rods. I paid for an accord k24a3 I believe (it’s been a while) like $400 bucks compared to what the tsx engine went for at that time not sure now but were like over $1,200. I built a high compression k24 bottom end and put a k20a2 head. My favorite built til this day. As far as transmission. Since I went N/A I went with a 5.0 final drive and KAAZ LSD. That thing gripped whenever I launched it.

[@Givelasagna]

@EduardoISF you have to watch out what k you get. There's an eco k that does not respond well to aftermarket upgrades. I believe it's the crv model

[@EduardoISF]

⁠​⁠@@Givelasagnayeah the one I got came out of the accord. It’s what was recommended to me. That Frankenstein combo is probably the best mix and match on a Honda you could do.

[@lunisic]

Best honda channel going

[@jonctr]

Thanks for that - There was also a higher performance PRC manifold for the JDM EP3 Type R, K20A (and probably the DC5 Type R). The EDM EP3 Type R, K20A2 had the PRB manifold as per the K20A2 based RSX Type S. That was a common performance mod in the early days on a UK EP3 Type R (PRB to PRC) before the likes of the RBC and RRC came around. It was rumoured that the UK Type R's had the more restrictive manifold/headers, milder cams and exhaust to limit power below 200 bhp (197 bhp) to keep the UK insurance companies happy, as some performance hot hatches nearly became un-insurable due to car theft in the late 90's

[@JamesDoylesGarage]

I have so much fun watching this channel. THANK YOU !!!

[@VTECAcademy]

Thank you!

[@davej6222]

The car shown at 3:49 is called the Acura CSX type S here in Canada.

[@lssi9073]

Acura Csx-S look similar but its totally different from the FD2 Type R. nothing is the same. CSX is basically an FD1 with an 8th Civic Si motor.

[@Ontheregz]

I have k20a from cl7 euro r, it has an rbc manifold. Bolted right in with the matching trans thanks to you guys. I’m collecting parts for eg subframe swap so will be talking to you guys again soon.

[@VTECAcademy]

Hell yeah!

[@WelshyAutomotive]

Lots of great information here! Always learn lots from the master himself.

[@lssi9073]

@VTEC Academy all the FD2 Type R k20 A i've seen, they come with hydraulic power steering pump/rack and not electric.

[@ruchgini2709]

Small error regarding the Civic Type R (FD2) having an idler pulley due to electric steering. The Civic Si with the K20Z3 had that, but the Type R put hydraulic steering back in.

[@VTECAcademy]

Very good

[@jnunez9771]

Would like to see the new k20c2 vs k20c1 comparison !

[@dannylongstreth4868]

The k20z1 had more hp due to different cams.. the z1 came with type R cams if I'm not mistaken

[@VTECAcademy]

True

[@kingmarz3635]

I finally convinced the inlaws to buy a Honda after their Nissan Tidia trans went, it only lasted two years and I told them not to buy a Nissan. They got a 2010 Civic 2.0 (k20) in black and absolutely love it. Good cos I’m sick of fixing shit for them. I have a KB1 Legend in black and my oldest daughter has a one owner 97 Domani (ek) with only 110k km, very rare Honda are number 1, they are the most successful name in the history of motorsport. This channel should be at 800k subs by now it strange why it’s not, keep doing collaborations with others and maybe hit up the Boostedboiz for one, they respect you Brian Watched from New Zealand the land of JDM, so so many 90’s honda’s still getting around but hardly an 90’s Toyota’s left even though twice as many sold

[@TassieLorenzo]

How do you find maintenance and upkeep on the KB1? TBH, I'm a bit of scared of all the proprietary parts that are on it that aren't on any other Honda (AFAIK) and the complexity of it. It seems like a Lexus GS300 or Toyota Crown would be a "safe" choice as it is a more simple car and more common, but is this unfounded? 🙂

[@kingmarz3635]

So far it’s been great the only thing that scares me is the leather doesn’t seem to last on this model but mine is still good for time being. The Lexus/toyota 2/3GR V6 engines are an absolute nightmare to work on as one cylinder bank is hard up against the firewall and them engines have their problems like water pumps leaking prematurely needing engine removal to replace and just this week my mates Camry Sportivo has developed a nasty rattle when cold which is most likely the VVTI cam sprocket bolts coming loose which is a very common issue with these engines and will result in bent valves if not sorted and engine removal is also needed. The 300hp J35A in my legend is centred perfectly with plenty of room to work on it. The only downside from my Legend is the gear ratio in the transmission is very long but ideally for cruising

[@nunyaf-nbizness]

Really enjoy and learn a lot from your vid's. I have a Euro R K20 ennroute. How about a vid test running one with the factory ecu on the floor to determine oil pressure, warm up for compression/leakdown test etc? Would be helpful to know hookups and maybe be able to read ecu to determine mileage?

[@maxxibro]

Accord euro R CL7 only comes with RBC manifold. 217HP Drive by cable, electronic power steering. RRC manifold comes with Honda Civic FD2 type R from 2007-2011. 221HP Traditional power steering and DBW. Flywheel is about 7kg ish. FS2 type R engine is an improved version of the CL7 K20A. Chromoly flywheel is approximately 4.68kg-4.7kg ish.

[@TassieLorenzo]

I think the stock FD2/FN2 flywheel is ~5.1kg (22100-RSP-003) while the aftermarket Exedy lightweight flywheel (HF02) is ~3.9kg. I think the Exedy (also sold as Toda) is the same flywheel, just with more holes in it, Exedy is probably the original supplier to Honda. I would recommend either, they seem to wake things up. 🙂

[@JustThePizzaGuy]

TSX throttle body is plug and play on the RBC Manifold as long as you use the 8th gen tb gasket

Ok so I'm having an issue with cooling where its not overheating its just cooling down too much. at idle and cruising its 192 F. soon as I do a pull 1st 2nd 3rd it drops to 175-179 f. and its changing perimeters in my tune due to coolant temp and getting knock but it not knocking its a whole big thing lol. just trying to see if any one has ran into this issue. With my old engine which was k20A3 didn't have this issue while running the same everything just different engine. the build is K20a CL7/Euro R Engine in an 2002 Honda Civic SI Ep3 engine is stock, radiator is stock, the thermostat is the hybrid racing K series adjustable, stock radiator fans, Honda blue 50/50 mix coolant. 4-2-1 K-tuned Header and custom 3" vibrant exhaust all the way back.

[@vevonhaye6703]

Am looking to build about 550 wheel hp or so for a daily drive car

[@CL9k24a3]

For building engines best one is k20z4 from fn2 civic. It has rsp head that has the most flow out of any k20 head. Intake manifild on it is trash and i'm not sure how cams compare to other stuff.

[@jamiecarey5076]

Fd2 has the cams for power. And the lack of a balance shaft. If you swap fd2 oil pump which removes blance shaft fd2 cams and fd2 inlet rrc inlet you make good power with all oem bolt ons.

[@TassieLorenzo]

The FN2's Accord-like RSP intake manifold is more for mid-range, it actually performs pretty well on K24 engines ironically AFAIK. Lose a little at the top but gain below 7k compared to RBC IIRC. It has pros and cons compared to the RBC and RRC -- the pro is that the K20Z4 already comes with it, so it's "free"! RRC & RBC are not readily available in Europe unlike RBC being readily available in North America. Some people port RSPs out or shorten the runners. The plenum is massive...

[@jkatman]

Only slight bummer about the z4 is the prb 11.0cr pistons and balance shafted pump, it is a sleeper fd2 k20a tho if you throw some rrc bits at it 🤘🏼

[@MrBluePoochyena]

@@TassieLorenzo It's actually a pain to be a Honda guy because the performance VTEC K-series engines are "rare"/expensive. I have a K20A6 atm and trying to source a perf VTEC head (K24A3, K20A2/K20Z4) is almost mission impossible, and trying to source a K24A3 or K24A2 is on the ~1900€ shipped pricy

[@TassieLorenzo]

@@MrBluePoochyena Oh no, where are you located? In Australia and in North America, the Accord Euro and TSX K24 engines are plentiful, although many of them have an automatic gearbox.

[@hassansafeer7411]

What's the basic difference between k24a rbb 1,2,3 ,4 ,....I mean the difference between k24a rbb 1,rbb2,rbb-3 and rbb 4.

[@jkatman]

[long reply warning] Fyi those 1-4 suffix numbers don’t mean jack diddly for designation of k24a versions or what model vehicle it came from. The Internet has made fake news about those damn numbers and people are drinking that kool-aide unfortunately. It will be rad if Brian dispels this in a future video on the k24 family. Those suffix numbers are relating to in house factories/warehouses locations honda pulls from. Has nothing to do with age or older or newer version of the cylinder head. For instance 2004 RBB-4 cyl heads exist which shats on the this whole internet belief the higher the suffix number the newer the head - total rubbish. The other side of this too is the international versions of the k24 RBB exist not just usdm k24 RBB and that in itself caves the whole reliance on suffix numbers. The best practice way of indicating the differences of usdm/jdm/intl k24a rbb’s is this: The RBB part number alone on the head and intake manifold instantly = performance version k24a (esp if the engine has never been split). An RAA number on head and intake manifold would indicate an eco/base k24a. Then there’s a 2-digit year stamp located on the side of head and/or on the exhaust port side of the head. The US 06-08 TSX/ k24a2 received some worthwhile updates the rest of the world did not get namely an updated larger profile intake camshaft. Also has 1mm larger intake valves (arguably proven useless). It also received a larger plenum RBB intake manifold and throttle body diameter which the rest of the world k24a RBB’s already had since 03 😂; the 04-05 k24a2’s had an raa intake manifold. In conclusion the best way to check k24 RBB cyl heads takes a little more work via “RBB” stamping, year stamp, and measuring the intake valve diameter.

[@hassansafeer7411]

@@jkatman OK thx for reply.,,,,my friends who own rbb-2 head k24a2,a3 ,they claim that their engine can maximum rev to 8000 rpm ,while other friends and including me ,we have k24a rbb-3,k24a rbb-4 , rbb-3 and rbb-4 easily rev to 9000 rpm .stock motor 100%,stock oil pump ,so as per my experience ,rbb1 and rbb2 are made for 8000rpm ,and rbb 3 and rbb 4 are made for 9000rpm rev .,and if they were all same ,then company would have stamped rbb only .but there is rbb-1 ,rbb-2,rbb-3 rbb-4 . And rbb-3 rbb-4 are way faster than rbb1 rbb2 ,on track .Still I am not sure about the built difference in all of these 4 types .but one thing I am confirm ,they are all different.

[@jkatman]

@@hassansafeer7411 idk about all that and where youre getting that info from, all of the k24 rbb variants all run the same balance shafted oil pump. The only version that would have a higher redline is the usdm 06-08 k24a2 due to the updated intake camshaft. Perhaps the ones that are revving to 9K have a prb type-s oil pump or rrc ctr pump upgrade.

[@hassansafeer7411]

@@jkatman I am telling you my practical experience ,I own 2006 model accord euro r cl7 ,I have recently swapped k24a rbb 4 ,head assembly ,with all the k20a bolts ons ,which include oem throttle 70 mm stock one of euro r ,rbc intake manifold ,I just changed my head assembly block from k20a to k24a rbb-4 ,no type s oil pump ,no rrc oil pump ,all stock head assembly ,and my euro r easily revs to 9k rpm .like it use to on k20a ,now it's k24a rbb-4 ,you can check my videos on my channel ,it's on stock oil pump ,that big one .Infact my ecu is also the original one which comes in euro r cl7 ,rbc ecu.i didn't even reflashed it after changing head assembly ,and still the ecu is responding so well ,first vtec on 4500rpm 2nd on 6000 rpm and 3rd kicks in at 7100 rpm.

True, in our minds the performance is close enough. But you're correct. The EP3 K20A3 oil pump has balance shafts where the RSX K20A3 has same oil pump as Type S. The EP3 K20A3 has same intake manifold and throttle body as RSX-S, base RSX has dual runner plastic intake manifold.
