Im tryin to build an N/A LS motor 4 my DA integra... how much do i need 2 do to make around 250hp for the street

 

A K-Swap with basic bolt-ons.

Since your in NC also. There's a guy in carolinahondas.com selling one right now for $3,500 for a complete swap.

 

yeah 250 hp isn't gonna happen with an NA LS motor, K swap would be cheaper and more streetable

 

check the all motor forum and do some research on how much people dyno. itll get you a better idea on what setups work

250 wheel is very possible on an all motor ls. youll need rods and pistons with a pretty high compression ratio. along with some beefy cams and cam gears for overlap. not to mention tuning.

 

Key to n\a is tuning, tuning, and tuning. You'll be running higher comp ratios which will require extrem presition. Ported polished head matched to intake and exaust. Very aggresive cam dual valve springs adj. cam pulleys rods pist crank bal. THe best way to price this out is go through the motor and anything that can break needs to be replaced with better than stock parts. Pretty much rebuilding the motor.

Ur proly gunna spend more than a quality turbo kit.

GO to the all motor section theyll be a lot more help

 

eh i dont think so. 1.8L? no way. its already hard to make 250whp on a fully built b20/vtec, its been done but its not like you can just pick up any parts and make that kind of power. you have to know your ****.

how about you post up how much your willing to spend on a build then you might be able to see how much whp you can make

 

i think king motorsports or another big shop built one that made like 190 whp and it was a big deal. my b20vtec with 84.5 mm bore and 12:1 cr will probably only make like 210 or so.

 

stock sleeves bored out to 83, some light rods and cp pistons with 12:1, some decent cams, valve springs, maybe a little portwork, tuned on some decent gas, yea i could see 250.

or you can resleeve and bore to 86mm with 14:1 or 15:1 and make some serious power on race gas. 300 wheel persay.

 

you cant bore stock sleeves to 83mm. way too thin. max you can go is 82mm. fully built 84x89 b20/vtec hit around 250-270whp. thats with a ported head. LS/B20 heads fully ported may flow close to a STOCK head VTEC head. ive never seen or heard of a b20/vtec with a stock head hit anywhere near 250whp.

 

thats funny. you say max bore is 82mm when the b20's bore is 84mm. not to mention some machine shops like jg have been doing it for years "Piston size
83mm / Max bore on stock sleeves." taken from jg's website.

 

u can do it no question. Just depends on how much money you want to throw at it and wat you wanna sacrfice

PERIOD

 

the best bang for the op's buck is to pick up a $350 b16 head. youve instantly got the same or close to the same power you would with a built and ported ls head.

 

b20's use different sleeves from b18a/b/c, b16a/b & b17a. b20 sleeves are made differently and the max you can bore them to is 85mm. the rest of the b-series can get bored to 82mm

id be interested in that link. ive NEVER EVER heard of that on stock sleeves. on resleeved blocks? yes. but never on stock sleeves

BTW
where is the OP? never responded back

 

look at their stage 2 all motor.

hate to say it guys but you should check out this in honda tuning where a guy named bisi go up to 450 out of an n/a f22a out of an accord so im pretty sure that you can get 250 out of an ls just if you got enough money and know how and this is same guy that came up with h2b and h2d adapter plates for tranny conversions

 

but he said "for the street" there's a big difference

 

lol. 250 isnt difficult today. Many ppl have over 300hp N/A. Just do research and find the right parts and get it tuned right. Its not that difficult by todays standards.

 

oh ya forgot to mention that was a sohc to bud so i know its possible

 

alot of misinformation here. looks to me like someone needs to go to the faq and so some reading before posting.

 

agreed.

 

ment the f22a with 450 whp

 

that has to be some kind of typo. i even spoke with EXOSPEED & GOLDEN EAGLE just to make sure someone hasnt magically figured out a way to bore an extra 1mm over what is safe. both of them said 83mm is IMPOSSIBLE on stock sleeves. 82mm max bore on stock sleeves. DONE


scan it and post it up.


if you think people are hitting 300whp NA on a NONVTEC B-series you got to be on crack riding a fcukin unicorn.
SHOW ME DYNOS!

 

hate to say i told you so but here is the link look in this paragraph go back a page too>>>>>>>>>>>>.....
Dohc What?
If things like variable valve timing and dual overhead cam engines bore you then chances are you've heard of Bisi Ezerioha. A Nigerian-native and tuning facility Bisimoto Engineering's founder, Bisi, thrives on non-VTEC, SOHC Honda engines. And why shouldn't he? The guy's coaxed more power out of the '90-'93 Accord's F-series engine than what others have from more hip-and-modern, big-and-burly K powerplants. Uni-cam power figures in excess of the 450hp mark are the norm for Bisi. Oh, did we mention he accomplishes all of this under the guise of naturally aspirated motivation?

 

just the problems is tuning and tuning and a crap load of money and knowhow so you figure a f22 sohc cam with 450 whp just think what a b18 dohc n-vtec could do
