I know a guy that has a built ls/vtec making around 250-260 to the wheels. He's taken first at IDRC here in utah and first at NHRA in vegas in the all motor class.

 

Do some searching for Tony the Tiger's old NA build. He was putting down about 240whp in a streetable GS-R.

 

weak. get a K motor.

 

Sorry to get off topic....But yes, 250 is possible in an na setup.

Edited to stay on topic...

 

Bolt on parts on a K series rival the high horsepower NA b series builds in power and especially reliability. Tuners make 240 whp on a k motor without touching the bottom end. The k series motor also doesn't have 13+ years of development under its belt. take a standard K20A2 out of an RSX. Bolt on a Comptech Race header, CAI and exhaust of your choice. Add a set of JDM ITR cams, some good valve springs, an over bored TB and a Hondata reflash. You're now looking at 235-245 whp consistently without touching the bottom end or head. You've got a more reliable motor (near OEM reliability), a broader torque curve (I-VTEC) and frankly, with a catalytic, you can still pass emissions, even a visual in Cali. And we've already seen what a little more compression (12:1) and bigger cams can do - 265 whp on 91 octane. the K-series today (in its early stages of tune) is already the equal of a fully developed B-series street motor. And you can get that equality with virtually no mechanical skill/knowledge. Just bolt on and go. As development proceeds (heads, cams, etc.) that power will come up substantially and eclipse the B-series. So jaime, maybe you can argue the other side of this?


So btakahas, you may be able to make high horsepower numbers on a dyno or fast times on the strip with a high compression NA b series, but as far as streetability and reliability goes, which motor will last longer, the one at the limit everytime you run it, or the one who's barely puffin'? A lot of teams in time attack events run k24's out of Honda accord. With their incredible low end torque, it makes for a wonderful street car and superior road course performer.

 

^ nicely explained. and just to add, the k24's bottom end is built better than a k20 fyi, which is if i were to chose a k series i would always get the k24.

 

skaterdude is FTW. anyone who thinks a b series is better than a k is just in denial. ****, if i had money for a k swap, i'll gladly do it.

This is true, K series is starting to rival the B series. But there are many thing to look at. As you mention Ulysses, B series has much more research and devolopment than a K series does. Of course the B series is going to be easier to make the power of a K, but this is all motor. In an all motor setup, the K and B are about the same; but when we look at boost aplications B is so much farther down the line than K series.

Also we have to take into consideration about transfering all that horsepower to the wheels. K series trannys aren't know for lasting long once you start making more that 300 hp, even the aftermarket ones. Of course this does go back to the time the B series has had to R&D.

So down the road, who knows where K will be. I can see the K surpassing the B given the amount of time the B series has had to R&D in the all motor realm. As far as fwd turbo apps, Im not sure who will stay on top.

So for know B>K, but for the time being. If someone wants to help in the pioneering of the K series, I have nothing againt that. I'm all about trying new things, I was the only one with an auto ls/vtec in my area.

 

I didn't ask for a debate; I simply asked people what the fastest B series build they've seen was, and if they thought there was a cap from around 240-250whp. I am not trying to get this thing locked.

 

skaterdude_10 = knowledge
HoodlumPyro = talky talk

 

I think Krazie made like 280whp all motor on his build.


Btw, I was wrong, he got 241whp, and figured 280 on race fuel Krazie's dyno picture

 

Guys, let's stay on topic -- he is asking about the B-series. There's no reason to launch an entirely different discussion on the K-series.

 

yeah I made 241whp on a mustang dyno...this is my daily driver so I keep it 91 octane... they estimate 280whp on other dynos

 

I didn't ask for a debate; I simply asked people what the fastest B series build they've seen was, and if they thought there was a cap from around 240-250whp. I am not trying to get this thing locked.

Exactly. He didn't want you to tell him how much better the K series is. Obviously, after new technology comes out a new motor will come out. But you can't deny that the B Series is an extremely reliable and all around incredible motor, especially for it's age.

I'd say the cap is probably 260whp if you're lucky.

 

I didn't know if you would see this Krazie, your build was the first thread I read on here, so I thought I would chip in.

 

From what I hear CFT has a built na b series making 256whp on their mustang dyno and runs 11.9 in a quarter

 

Krayzie, Could you send me a list of your internals? I am running a Built GSR w/ Internals, and am curious to how much I will dyno in at if I was to drop stage 2 cams in my car.

 

i belive there was once a mention of a 600hp drag motor all motor take that k series

seaching but i might be wrong

(edit)so cant find that 600hp monster but it can be done with lots of money and race gas. also you need to search next time there are mutiple post on this

here

and here

 

i hear all this talk about power, but fastest to me is how fast you go down a strip
