I was just wondering...

i have a b16a vtir. If i wanted to pull 135-140kw without a turbo how would i do it?

ECU - how much can you expect from an ECU? because i heard that the stock ECU is very efficient in itself already
zorst - 1k - not much difference i dont expect
headers - how much does it cost and what response to expect?

any more????

and no, sticker decals will not do me any good! :)

any tips appreciated

i dun think u will ever reach that number with b16a engine...but anyhow you can make it faster by get the head completely rebuilt (port polished, cams, etc etc), stand alone ecu will do as well..

ur gonna need a major build for 140kw.
new valvetrain, 'stage 3' cams with plenty of revs, higher compression, some lightweight pistons (forged) and rods. a good fully tunable ECU is on the cards no doubt. high capaicty fuel system also.

Thats gonna cost more than setting up a turbo kit.

Too much money wasted imho.

no weq, its not going to be possible to get that much power from a street car b16a. he would need more capacity to get that sort of power.

i mean as in not on optimax, and not at the wheels.

if ur talking flywheel then u can do that.

hmm really? i know u'll need some big compression but.. o well i got no experience in this area =]

12+:1 C/R
1800cc kit + Spec B camshafts, springs, gears, oil pump, header, exhaust, CAI, fuel pump, regulator, 66mm throttle, Type R or better intake manifold,
Programable ecu is a must...
Bloody good tuner is a must...
Deep pockets is a must...
Good headwork is a must...
Combination is everything, so long as it's put together well & tuned well...
Any flaws in assembly or tuning will hobble your power output.

i didnt mean 135kw at the wheel maybe 95kw at the wheel

i was just comtemplating the value of me modding my car soon, sat stock for 1 year.....have that bad itch to mod it but unsure!!!!


if you think about it.....

118kw +
5kw (zorst)
1kw (air filter)
10kw (ecu)
5kw??? (headers)

(i know that that is generalisation but HEY thats how you do it on Gran Turismo! haha)

and your in the 135 kw range itself already....

isnt it as simple as that?

how much will it cost? around about 4000 bucks?


isnt this right?

dude I'm running a JDM b16a and I'm already putting out 98ish atwheels, with CAI and cat back. you'll get 135-140 at the fly with those mods easy.

kw is very gernalised. Each dyno spits out a different reading... so you cant always trust them...

The money getting a b16a to 140 would be better spent on a higher displacement engine or forced induction in my opinioin

mm my car is about 90kwatw.. to get say, 105kwatw.. intake + header + exhaust + hondata or another programmable ecu has proven to get that much on n/a b16a! just ask bizee_1, how much faster than makes on the 1/4, i dont know..


with CAI and cat back. you'll get 135-140 at the fly with those mods easy.

22kw at fly with catback and cai... no way! my car has catback and cai, i got 90kwatw with those mods (on a day where stock itr got about 105kwatw)

i agree with SIKCVC to sum degree... b16a only needs good quailty zorst system (xtractors,cat,n cat bak) n CAI n it can easily reach 135kw at the fly... full zorst from hi tech on a barina gives 9kw n on an s15 sumfin lik 20-25kw (do not quote cos ive only heard these stats). on a b16a ur lookin at d very minimum 12-14kw... dat brings it to 130kw right der n dats using minimum estimates... den u hav CAI n airy... for full zorst n CAI shouldnt cost more den $1500... all depends on where u get it from too

I/H/E+hondata its all you need to break the 100wkw mark. My bog stock b18c pulled in 105wkw only with Hondata :o

so many inflated numbers?

latino, what was ur base run?

James roadtuned the car a week before and I also did a service before the dyno (fresh oil/plugs/oil filter.

We jumped straight on the dyno so the first run with hondata roadtuned was somewhere aorund 97wkw.

I hope that helps.

Wouldn't it be less hassle to go find a B18C if you are chasing a 140kw target?

no. maybe changing the block. even then i wouldnt bother

all these values......!

i highly doubt CAI + Exhaust will take me into the 140kw range......

thats like saying....with those mods, my car can take on a civic type R or something

i'd expect getting me close to 127kw........and the integra vtir can still rip me a new ass due to the torque that it has

i sit in my friends civic vtir with exhaust and CAI and extractors

i mean, i feel a bit of difference but those differences feel almost to the point of nothing......might have even been exaggerated by the sound of the exhaust too.
anyone know how different i can expect from a set of headers?

and if headers will be anygood by itself without exhaust?

or if ECU purchase requires better air flow (exhaust) to get better return in KW?

what is the best first option to get for return in power?

if i dont get much feel and response from an exhaust, what are my other options?

r u guys serious? 135kw wif basic i/h/e mods for a b16a??? so that basically means ur on par wif a b16b ctr engine... which rates at 136kw, prob on ron 98+.

00' coupe: u can't compare an exhaust on a barina and s15 to a honda. turbo cars especially have very restricted exhaust systems that's y wen a better system is installed there are alot of gains. barina? i got no idea how it can gain 9kw... lol. honda's put alot of r&d into their engines/performance/fuel efficiency to get as much power out of their small capacity engines as possible, so i doubt u can gain anywhere near that figure just wif an exhaust.

to get 140kw from 1.6 would definitely need deep pockets. make life easier by just doin a 1.8 swap... will be cheaper and have more potential for power.

yeah some of you guys are talking kw atw, and some are talkin about kw at teh flywheel

William
17-11-2004, 04:28 PM
okay....at the wheel

atleast 95kw ATW
which goes in tie with maybe the civic TYPE R

what mods will i need to go through to get this amount of speed

and what order should i follow

I/H/E+VAFC/tuning.

Now you can go and do some research :thumbsup:

so are you putting out 98FWK with a standard sir b16a?

mate,

just my opinions on your goals, i dont think it is possible to achiece 135-140kw without major work done on it.

i have read your thread and if you want just want to squeeze out every kw on the engine without the doing internal jobs, just do a basic stuffs like

air intake, headers and proper exhaust system and some tuning tools like cam gears or some basic apexi vafc2... i know vafc2 is not a complete tool but i think it is sufficient if you want to gain some with the mods that you have.

but i do notice that people dont tune their car after putting the air intake system and the exhaust system. you need to tune them and cam gears is a great tool to do so.

also for a car to run well, all must system must work together.

the purpose of an exhaust system with headers is to expel fumes as quickly as possible. in an n/a car, you are after velocity of fumes so that a batch of fresh air will fill up the combustion chamber ready for the next combustion.

so a typical honda will have 4 cycle
1. Intake Stroke
2. Compression Stroke
3. Power stroke
4. Exhaust Stroke

and after the Exhaust Stroker (4) it will return to the cycle (1) again.

if your engine doesnt expel the fume quickly and the next cycle of combustion will not be as good since you have a mixture of air+fume+fuel when it is supposed only air+fuel predominantly and it is ignited by the spark from the spark plug

we know that to have the best combustion, you need as much oxygen as possible.. thats why people put NOS system into the car as Nitrogen is 36% oxygen by weight compared to atmospheric air which is 23.6% oxygen. Finally got to put what i have learn in high school! :D

again in science, you cant fill somthing when there is something inside ie. the combustion chamber (cylinder) cant be filled with fresh air, if the fume is still inside.. putting an exhaust system will help to do so ie expel the fume faster.. but people forget to adjust the timing when the valve open and closed. it is like having a major improvement on a toll way (widen the road so that more car can fit in) but forget to adjust the trafffic lights amber duration. if you have a major toll way but the duration of the amber is too long, it wont solve the traffic problem either... not the best of illustration but i hope you get what i mean.

so get a proper intake system, exhaust system (header, catback) and tune your car. there is dyno dave and i have heard good things about him though i have not meet him b4.

the best cam gears that i have ever seen and the easiest to use would be Toda cam gears. But this is just my opinion. i have seen many on the market but none can beat Toda in term of quality and ease of using. The marking is so big that it is easy to tune and very accurate.

Also Apexi VAFC2 is again just one of the tools to use it, you dont need to use it if you dont believe it is useful. i guess you must be confident with the product that you are using.

Just my 2cents i guess
