Realiable Vtec killer

[Onasty]

I know everyone is very scared of this setup but i feel from my own experience its very realiable. I was tuned all motor on it and went 197whp then i went turbo on it for 305hp. I had a child and decided to take off the turbo and sell my ecu but still drove on a stock ecu with it. The car still ran and i was still able to drive it everyday on stock ecu the only down side was, that i had to keep my foot slightly pressed down at red lights to prevent stalling. I just got Kpro again after a year and uploaded my tune and this car still drives like a beaut time for my to get back on the forum.

[303EP]

Thanks for this thread, I was worried about reliability as I'm doing this in a month or two

[Yomimito]

is reliable, I have already 9 months without any problem. it is worth doing.

How many on killer vtec? 197 whp on a stock a3? I'm doing a slow killer vtec build, but I'm going with much better components. I'm hoping to pass 220 whp.

If anyone needs k20a2 cams or ep3 exhaust rockers lmk

What are you planning on doing dont invest too much money.. I do realize boost is best dont spend too much money going all motor by the time you know it you would spent the same amount going turbo.

Im finally going to go to a dyno and see where the car sits now because i did change my header, exhaust, manifold and intake. I will aslo upload my grap when i have time

For sure. Post up results.

[RHCP0801]

pretty much the same results I made with skunk2 stage 3 cams

[Onasty]

quater of the price though

[USAF EP3]

Just keep in mind fuel ecomony will go down. Think of it this way: when in high gear cruising on the highway all 3-lobe VTEC engines will be on the primary lobes and not engaged in VTEC. With VTEC killer you will be using the secondary lobe at cruising speed and dumping more fuel to sustain cruising speed.

I love the concept but I personally would hate it since I commute too much daily and my wallet would hate me too, lol. Very practical if you plan on tracking/auto-x/drag strip with the engine.

[RHCP0801]

I wouldn't say that, with tune it only cost about $800

Really?! I thought I was going to get better gas mileage..

Come on bro, no need for the sarcasm. I always have redundancy in my posts so when newer members use the search option they can have good and accurate information available relevant to the thread or subject they want to find out more about.

I guess you can say I take from Doug (talonXracer) alot he used to post like that as well.

Oh boy if your worried about gas mileage dont do this mod at all.

What's your gas mileage like?

[Onasty]

What's your gas mileage like?

Dont know the exact i would say normal if you drive normally but if you WOT around its like 10mpg. It also depends on your tune it was the first time my tuner tuned one of these so im also running a little rich.

:roll: Dont be mean lol. He just being curious. Im running rich on practically bolt ons and I might have a vacuum leak somewhere
180miles a tank lol. Im complaining that Im not modded enough to deserve this lol.

[RHCP0801]

wow 180 to a tank lol, that's pretty crazy. I get about 250 on my fully bolt on k24a2 which takes 93, I hate it lol but I knew what I was getting into

I have to figure map on kpro. Or either Idle Air Control Valve or Vacuum leak. I run 91oct in mine. Dont mean to thread jack back on subject here look. Its more then 180 lolhttp://img.tapatalk.com/4606d581-0e17-6bc7.jpg

It was 180 when I seen the thing on e.

Holy hell horrible mpg in this thread!!! I have TalonXracers old Ep3 and recently driven it was getting 300-350 a tank! With around 85-90% of that being highway, but WOW....

I should say I made a few minor adjustments to my Kpro map for the Spring, but still.....if I had that low....I'd sell the Ep3 and finance a C5 Z06.

[tlikethedrink]

So I've been reading about vtec killer ALOT past few days...
Still, I wonder:
-how fast is it anyways? Onasty has a vid doing 15.5... Is that with the a1 head/killer?
I understand hp will be anywhere from180-200whp and the dyno's look like k20's that come stock with 200. So does that mean its as quick as a swap or a Jrsc-s EP? Can I expect to hang with Rsx-s and newer si's? Other cars?

-mpgs obviously depend on a tune and most importantly driving habits. The guy on k20a.org said he was in the 27-28 mpg range(where I was at with boltons), I could live with that : ) onasty mentioned 10mpg while getting on it, to me that means atleast 18-20+mpgs if driven "ok": right?

- the bottom line is the tune. Is anyone running off the shared kals? Midastouch and djcarbine share tunes on k20.org- I know they are good starters: I have no kpro or any other tuning experience... Can I get by with these kals for awhile?
I don't even know of anyone that street tunes! And I would most likely try and find some one to etune on a dyno later. And thats a whole different problem: find a dyno and an etuner that will keep the budget reasonable.
I can always learn kpro but I'm sure it will never be as good as some of these kals online.

Bottom line is I think it's worth it: $100 cams, $50 rockers and used kpro around $800 if I'm lucky! Hopefully with a free kal and some help from the gurus and I can drive it if I need to and have a little fun doing it :) . Then say in a month or so- a better tune thats prefferably on a dyno with Rsx injectors.

[1GR8EP3]

if you are worried about mpg's dont mod your daily driver... with that being said if you do plan on running the vtec killer set up I will tell you that "in town" driving drinks gas, I think I was getting anywhere from 15-20mpg in town. On the freeway its different, i was averaging 26-28mpg's.... so an average fill I would normally get around 280 to a tank, when I was careful and babying it I got a little over 300.... but those were few and far inbetween haha.

I thought it was worth it, so I think you should be able to hang with bolt on acura's or si's. I was doing it with skunk stg1 cams, cai,dc rh, greddy evo2 exhaust, kpro tuned. I cant remember the dyno number but I think it was around 170whp. Just depends on what you want to do, I forgot the member's name that was just running a k24a1 with bolt ons and he was hanging with a s/c type s. thats impressive, the torque does well with the 5 speed. hope this helped you a bit..late

I just saw this the 15 sec pass was my motor when it was stock with just kpro and skunk 2 exhaust. The best I've done with vtec killer was 13.9 on my friends street radials. If you look through the videos I think i have one of 14.1 run on winter tires and Gtimportfanatic also drove my car at the track and hit 14.1 on the same shitty tires.

AND its still kicking strong best bang for my buck :) .... (knock on wood before my shit blows tomorrow)

And...... yes i beat on the car everyday to and from work.

You still in the area bro...looking to do the vtec killa install...interested in a side job??

Dont forget you can use the 3 lobe rockers on the k20a3/k24a1 head with 3 lobe cams and gain the same power as VTEC killer... BUT you have VTEC and gas savings. Flipped pin VTEC. Been bangin it for a year with no issues...

[Blah1219]

Ba82Ep3 :which 3 lobe cam's are you talking about?

K20a/ a2/ z1/ z3
K24a2

Pick your poison.

[Ba82Ep3]

Ba82Ep3 :which 3 lobe cam's are you talking about?


K20a/ a2/ z1/ z3
K24a2

Pick your poison.

Yep, yep. ^^^

Im using k20z3 cams, three lobe rockers, three lobe rocker shafts, yellow outer and red inner OE valve springs/seats/retainers... the rest is either k24a1(head casting) or k20a3 (the rest of the valvetrain/head internals).

If you look at the above pic you can see the left rocker locked to the VTEC center rocker... the shiny pin is easy to see between them. Below the VTEC crossover, the right rocker rides on its own cam lobe (gas savings).

The left cam lobe is never used. The left valve is on the center VTEC lobe all the time... at the VTEC crossover the pin slides to the right and locks all three rockers together and they all ride on the VTEC lobe (bbbbwwwwaaaaAHHHHHHHH!).

[los]

so in my a3 i would need the cams any of the following "K20a/ a2/ z1/ z3
K24a2" and three lobe rockers right what do the rockers come off of? and as far as springs retainers and seats i cant use the ones that are already in my a3 ?

You can use the a3 valve train. Your able to reach a much higher rpm with a2/z1 valvetrain without floating a valve and fucking shit up.

[wcmbrk]

this is probably dumb question, but do k24a1 head and k20a3 head use same exhaust rocker...i want to vtec kill the k24a1 head i bought 3 yrs ago and did nothing with...thanks for any follow up info...(just ordered z1 cams from another user)

K20a3/k24a1 have all the same rocker assembly/ valve train/ cams. The only difference is the beautiful ports on the k24a1 head casting.

[wcmbrk]

thanks for the INFO bro...much appreciated.

[EUB44]

I hear different things about price. How much does it really cost to get same power as k20a2 with this setup.

After starting my build planning to go this route, then for many reasons changing my mind. I would suggest swapping instead. In the short and long term you'll be spending less money and getting more power.

I'm now in the hole about the cost of a k20a2 swap, and right now still wouldn't be able to make near the power with the a3

It can go either way for me it was way cheap since my frank swap blew up and I had the a2 head componets just laying around. So I got another k24a1 (that I got for free for doing some work) and did the work on the head then bam cheap power haha.

But for some who dont know how to do the work and have to pay to get it done then the labor starts to add up along with parts you might need... and if you need kpro thats a big chunk right there but it is a much needed part.

all in all just depends on the person (if they are mechanically inclined) and weather or not they can get the parts for cheap.

[whatsvtec]

Even getting the parts for cheap, It cost me about the same as the cost of the swap. That's why I'm just going fully-built a1 head instead. Low end and midrange power, more reliable, and it'll be ready for boost.

[Ba82Ep3]

Stock for stock... its hard to be the k24a1 head.

The cost is the bad thing about the flipped pin setup... the three lobe rocker assembly can put a ding in your wallet. BUT, if you stumble across it cheap, or in a yard... youre golden.

Indeed it is. My old car has almost 40k on the locked-rocker setup on a K24A1 now. Might as well be a stock motor.
