**How do u build torque in a B16a?**

[Gudgen]

how?

[UR2FAT]

By getting a B20Z block and slapping that in along with one of those T88 turbo thingees.

You should be able to gain a bit by freeing up the exhaust, getting a decent intake and a bit of tuning (assuming you mean low down torque). After that, basically increasing the displacement - B16As and torque don't mix.

when u mean free up..do u mean big arse 2.75" exhaust and running a 4-throttle intake with a bit of tuning....?

or...ditch the block for a 2.0l vtec block?

Torque is for v8's, b16a's have a near perfect rod:stroke ratio which is mint for high rpm. You're bettter off building one to scream, or getting a b20 block if you want torque [or F.I]. I noticed the gizzmo chip and tune gave me the biggest increase in torque/mid range power (going by how it drives, and how easily it spins wheel).

[Gudgen]

mmm...true. but tell me wat is a high rpm screamer good for??

what is a high RPM screamer good for? 1 silly billy dude..
FOR UMM GOOD PIZZA! hahahah lol nah joking, im guess GOOD POWER?
TORQUE - NOTHING Is TORQUE WIF A B16 DUde although, get a B16 Civic Type R head which is ported - and raise a bit of comp, but not much, free flow exhaust - 2.25" or 2.5" exhaust and free flow cat, filter and intake, cams, internals?
fully build or go FI

[Gudgen]

define GOOD POWER??

[Cyclone21]

170hp out of a 1.6litre 10 year old engine is pretty fucking good power to me man.

b16a are made for high rpms, which in turn produces a good power output. You can increase torque by minor amounts with basic mods, but to gain a large gain in torque either increase displacement or use forced induction.

If thats not enough, go buy a V8.

[Matty]

I think temposir means good power-per-litre.

Obviously you need around 400hp in a Civic before you start getting to the point where you think you've got enough, but for a 1.6 the B16A's actually not too bad as far as low and midrange torque goes. A DOHC VTEC engine is built to be driven in a different way to most engines - it's meant to be revved, not lugged along under 2500rpm.

Probably the best way to build low and midrange torque would be with a Roots-style (eg. Jackson Racing) supercharger. Check JR's site (www.jacksonracing.com) for some dyno graphs - an almost flat torque curve, which is similar to a traditional V8 curve, albeit somewaht lower down the graph. :wink:

IMO a "screamer" is good for the track as there's no drop-off point since you're normally up high in the revs. On the road don't forget the B16A is still king of the under-1600cc brigade.

If you want torque from idle the old adage still holds true - there's no replacement for displacement.

[DA-seX]

If you wanted to sacrifice high-end for low-down torque (like, your granny wanted to you to modify her car for you) get some cams out of an automatic (different grind) and play around with the timing and stuff till you've flattened out the torque curve a bit. But I guess that's not what you're after... ops:

Why did you buy a car with a B16A if you wanted a torquey beast? better off with a V8 (ugh - pushrods )

[Gudgen]

well i went away and did i bit of research came up with this..

first you must convert ft-lbs to nm-1 to get the "wow!" factor out of this.. ok..here we go...

one example:

APEXi headers designed for JDM teg type-R
RS Akimoto air intake
milled cylinder head about 0.035"
EH porting of the head
modified factory intake manifold
Holley 68mm throttle body
stock camshafts
AEM adjustable camgears
Hondata
a whoping 2.75" open exhaust

with careful tuning it produced..wait for it..177hp@the wheels with 126 ft-lbs of torque@6700RPM

[Gudgen]

thats about 160nm right?? cant tell me that that doesnt have a "WOW" effect on you?? 8O

[Lith]

Hmm - H22A conversion Go for 230nm+ once you get a few mods into them...

[Matty]

160Nm is about standard for a B16A. :wink:

With a B16A you're never going to make huge low-down torque without FI, so you might as well go for top-end power, which if you're revving it will make up for it.

177hp @ wheels is pretty impressive though.

dang!! i suck..

lith: dam straight for an h22a. maybe once ive got as much as i can out of my b16a. cant let all that work go to waste.

stick a turbo on it.

[Bullitt]

A stock B16A has 115 ft lb of torque. B18C is around 125-130 I think.

With that above setup put a smaller exhaust on it and itd gain some power back, thats way to big for a 1600 NA with relatively minor mods

[AL-]

in your opinions would you go for a 2.25" or 2.5" setup on a b16a with basic bolt ons ?

[Bullitt]

2.25

[SQUERT]

yea i think defniatly tha 2.25 would be beta...
