- I rundown the different options for rockers with a Vtec Killer cam setup on my K24a1. This works with the K20a3, K24a1, K24a4 and K24a8 engines with the non performance I-vtec systems.
also the k24z3 rockers spray oil directly on the cam lobe and u need the rocker shafts as well to match not just the arms lot of people mess this up and u get less oil fed to the intake rollers and lobe the a3 had oiling problems so there prone to eating the cam newer style corrects this problem
Thanks for doing the trial and error and putting the info out there. I learned so much about ls motors from your stuff and its happening again with Honda
Back in my bseries honda days the TODA vtech killers were the absolute dream haha highlob all the time full party!
I like people that think outside the box and try new things.. subbed
no idea what you're talking about but i enjoyed this video :)
VTEC is just a way of switching to a more aggressive can profile.
It essentially gives you 2 engines. a quiet one and past a certain rev range a nuts one.
Soon as you get on the gas. Vtec right off rip.
Thank you man this video has helped a lot because basically this is the only video I could find that explains like everything like what has to be done and like parts and stuff.
Your explanation is amazing and i thank you for posting as i am ready to do my sons engine.
The main purpose of VTEC killers when TODA designed them was to reduce weight in the rocker assembly to support higher revs (10K RPM). Thats why someone with a K20A2 or performance VTEC head would do VTEC killer setup.
Does this not do that?
this some top secret shit u teachin us damn
I have an a4 man 104 mph almost 240 whp no prb oil pump oem low.comp pistons just rsx cams and vtc and full bolt ons if you check some of my old videos you will see ive been more than 6 years v killer 0 problems just dont rev to much even if you dont flat the dyno curve
K24a4?
The 2200rpm kick you are speaking of is the 12 to 16 valves activating...the vtec kicks in at 5k rpm on the k24
Thanks for the tutorial, Dario...I have 3 Accords in the fleet, all running this engine...just good to know what is going on under the valve cover...
dude thanks so much for doing this
Are there any performance camshafts for the economy vtec k24s that aren't vtec killer? I've got a k24a8 with every bolt-on imaginable but it seems like without an upgraded cam it won't make much more power
...and it needs more compression.
i just get cams non used lobes ground off the cams and use the k20a3 rocker arms also get them to grind base circle on the vtec lobe to get bit more lift and duration thay work good and cost like 300 to do
I bought my 2016 CRV just for the K24. I should have done a little more investigating because it's an earth dreams vtec with reversed head. K24w something.
K24Z
Is it possible to just use a k24a2 type r head on the k24a4 block?
Can this mod be done on a 2013 Honda CRVK 24 A1 engine. I would love to get just a little more out of it it’s so dead off the line
Can you use the bc1050 springs with stock retainers and keepers ? Great video and info 👍
So I had a question for you. Loved the video by the way. Would I be able 2 put better cams in a 2015 2.4 liter honda accord. What would you recommend can you help me
K20a3 came in 02-05 civic si and 02-06 base rsx
I have a 06 accord with a k24a8 what do I have to replace to make it get 200 hp instead of the 160 hp ?
U has 166 the 8 has more the the 4
I said it has 160 because the engine has 105,500 miles on it im guessing it had some sort of hp loss by now
What cam gear are you using and what degree you set your vtc?
So my k24a4 in my Honda Accord only had the economy type of Vtec I assume
Yup not a bad starting point though
Thanks for the video
How would you get around the clip issue on the k24z3 rockers with the 06-08 tsx cams?
Bro can i use the k24 rbb cams on a k20a3 head? And do the vtec killer setup?
Any updates on the car? Looking forward to seeing this car finished!!
I have an k20a3 that i got for super cheap. can i just swap an a2 set of lifters and cam on it.
I wish I could find a cam from a different honda for this
I was planning on getting tsx cams 06-08, and put it in my k20z3. Should I just put in the intake camshaft or, do both camshafts exhaust and intake.
in for when your huge lumberjack body is in this thing ripping around lol!
have a k24a4 can i just vtec killer the exhaust and keep intake vtec cam
Great info! 👌
Gr8t video , question wen doing cam upgrade ,do both cams need to transfer over from k24
Thanks for this
hi i'm starting a k20a3 project on a Civic 81 body! I want the vtec killer configuration, I don't know how to protect the motor so that it does not break, can you help me?
Quick question on the K24z3, would a VTEC exhaust roller/camshaft swap increase the horsepower or would it actually hurt the engine and mess with the variable timing? As my research has lead me to see that almost no one really does any k24z3 cylinder modifications and rather throw it out and swap it for a k24a2 cylinder head or similar….. I would like to keep my k24z3 cylinder head and was thinking of changing the exhaust rocker or camshaft and covert them to VTECH, unless it’s impossible or pointless….
So i have a 03 k20a3 base automatic rsx. If i want to try this out i would just need another set or exhaust rockers off a base and k20a2 cams intake and exhaust?
With a K20A3 Vtec killer setup using K20A2 cams and A3 exhaust rockers on intake side can I use the stock A3 cam gears on the A2 cams?
This might be a dumb question but could I use my k24a1 exhaust rockers on a2 cams and put k24z3 exhaust rockers on my intake cam and get the same results for VTEC killer?
So... A3 head with tsx rockers and a2 cam? Drop in?
Might be a stupid question but I want to run the K24z3 exhaust rockers on the intake side of my k24a1, do i need to also change over my k24a1 exhaust rockers to K24z3 exhaust rockers as well?
Oh and one more question. Do I need to retune of flash my factory crv ecu? It's my first time building a modified motor so I want to do it right 👍
@thehouseofboost, have a question. Whats needed to lock vtec on 02' K20a2 engine besides the lock pins?Thanks in advance
K24z3 rockers: can you use the shims instead of the funny daisy looking clips?
Will these rockers work on a RSP or PRV head and what OEM cams will work for these heads? 06-08 TSX cams will work?
Thanks.
A little late but why didn’t u use the vtec lock pins to lock the vtec lobe? But thanks for the info and your hard work! Pls keep the videos coming
Cause this is lighter and can be pulled at the Yard
So could I cut my exhaust ones on my k24a4 for the intake side and use k24z7 exhausts rockers for my exhaust side ?
Wait so one side is activated by rpm and one side is always locked on?
I take it the Accord/ element are economy vtec? So these rockers will bolt in place on a economy valve trane?
Can you just cut or grind off the unused cam lobes or narrow the center cam lobe?
Yes you can grind the low lobe off and narrow the high lobe, a company like delta camshafts offers this service. This was more the way of making it work with junkyard parts.
Do they sell a VTEC killer kit premade that you could just buy
Will this works for a K24w1? I know is the not the best K series engine. My wife's Accord trans died and I have a K24w I pulled from that car that I was hoping I can upgrade it for performance.
What about the vtec solenoid, do you remove and block off?
The K24A3 is the same as a K24A2.
What about the diameters of those rocker bearings? I wonder if certain model rockers are just slightly bigger than the other?
What the best for 08 element
So what would be best for my k24a4?
Whats going on man ? Any updates on projects?
what if i still wanted the VTEC to kick in and not just stay kicked in at all times? can i use a rocker that has like 3 arms to support the 3 lobes? i have the 24A8 btw
No because the head in your motor doesn't have the provision for Lost Motion Assemblies
why do you want to delete vtec?
👍👍
would you say it works on k24z7 as well?
So from what I understand here... If I used A3 exhaust rockers for my A3 head, they fit the intake side but they don't fit on exhaust side where they are originally from..... HUH?
Yes, it hits the primary lobes which your a3 doesn’t have stock
@@Thehouseofboost So my K20a3... Which has factory rockers on the exhaust side cannot use K20a3 exhaust rockers on the exhaust cam.... Where Honda puts them in the factory? Are you certain?
@@Thehouseofboost Also, the A3 only has 1 lobe on the exhaust side, no primary or secondary.
This is with k20a2 cams, of course the a3 rockers will work on a a3 single lobe cam.
@@Thehouseofboost Ah okay I was thinking of just the vtec killer setup with stock cams, that makes more sense. I think will still try to track down the z3 rockers in case I do upgrade to a2 cams in the future. Thanks for the info
is it compatible with the k20z2?
Which one k24a8 do you recommend?
does this work for the K20z2?
Will this work on a K20C2?
Looks and sounds more complicated than it really is once you know what you're doing . It's like a puzzle , if you can put a model car together you can build an engine granted you have the proper toolage and manuals . Electrical problems is what kills me 😂 wiring and ohms voltage and blah blah 😔 I leave that to those savy ones I have zero patience for such things 😂
Is the k20z2 the same as the k20a3?
If it’s 2lobe yes
can k20c2 do vtec killer? its an eco car.. it has vtec but only in intake and makes 160hp.
Send me where can buy this stuff?
Any update on little tab washer did you grind it after all or we dont have to grind it thank you
can i use k20z2 rockers>?
Man...., this uahhhhh, is actually good info, but uahhhh, you think I could uahhhh, just remove/machine away/grind away(whatever youd like the gender of the process to be) the unused lobes? Uahhhh... lol 😅 so that way we dont compromise the rocker arm integrity and also thats alot less rotational/pointless force against the rollers too Que no? I mean fuck it yea I guess your technically ruining a set of say $100-150 stock type s cams but obviously the point is making a peasant k series and make a competitive adversary using on hand or readily available parts, you know clean out the cobwebs on the debit card and invest at minimum into away higher volume oil pump and might as well go over kill on the valve springs and get some high end ones so we can pray to minimize the inevitable premature wear to the cam lobes but if done thoughtfully I think it could be a very very reliable and extremely cheap alternative, basically the intuitive peasant secrect mod budget engine? 240+ has been seen on stock k24a4/a8/a2/etc. blocks running any of these single lobe style rocker per required mods, hence my complete single lobe idea, I feel like that will significantly prolong the life of the engine beyond what the average person is willing to do because if your building one of these engine yourself you can handle grinding/milling whatever you do to do remove the useless lobes. Cams dont have a critically precise balancing process so I feel like its just even more of a + to remove said material from the unused lobe instead of the rocker arm, im not a genius but I've personally built a 280+ all motor b20v and that's just my public show off build, I could be wrong there's always more than one way to skin a cat so someone chime in with me I see no reason why it wouldn't be beneficial? Some one chime in, dont waste your time with comments about me wasting my time, I build engine for fun im looking to do something significantly abroad
Bro k24a1 sucks bro shoukd if got k24a2 like mine i got 05 tsx k24a2 with full acura type s internals
actually k24a1 PPA heads flows much better than the TSX Rbb heads, it just doesn't have the real performance vtec hence why you'd do a vtec killer setup on the k24a1. I wouldn't do that do on a street car but its a cheap way to get some power on a race engine
