i was wondering if anyone could tell me of simple mods to get torque. vtec is nice and my single cam raps out nice but i am tired of cars pulling on me when they shift any ideas. thanks

 

buy a mustang...

seriously japanesse people don't have torque in there vocabulary.. ask them for torque and they say "oh, how you want that on a plate?" lol

4 cly = HP - torque... unless you go forced induction.. hehe

 

supercharger

slicks

weight reduction

Of course the last 2 wont actually give your car "torque" that can be rated but will lower your e/t and take a chuck out of your 60'

This is totally wrong and narrow-minded. Have you ever heard of Nissans or Toyotas. They're japanese and have more torque than Hondas.
Torque is function of engine design and displacement.
Small displacement, high-reving N/A engines like Hondas lack low end torque due to their inherent design.
PS if you want REAL torque get a Viper or a Vette, or a Hemi.

 

if you want more trq retard your timing a bit you will see more trq but less hp and you can raise compression with a thinner head gasket thats prolly it without doing major engine work. Take a class on engine performance theory then you can make some real torque out of that n/a 4cyl

nissan and toyota? psssh, as the guy said earlier, if you want torque, DONT GET A japanese car. they dont have torque. compare two cars...older sw20 (jspec), and s15 (only jspec...so duh) both when new, vs a camaro z28 (ls6 i think). both would cost you about the same amount of money (after converting yen to dollars). but which has way more torque. again, compare a z06, with the supra, r34, nsx....what has more torque. even look @ the new c6 base vette, comes w/ 400 hp, 400 tq (ls2) and thats all motor, no turbos. wait till the z06 c6 comes out

 

You want torque?
How about a 425 Caterpillar?
or a 671v Detroit Diesel?
Vs your stupid little Hondas. You guys make me laugh.
You guys make about as much sense as a submarine with a screen-door.
If you want TORQUE!!!!
You need a LARGE displacement low to medium reving over-square engine.
It's that simple.
You cannot compare, 2L or sub 2 litre jap engines to detroit V-8s. Its just as stupid as comparing Corvettes to bulldozers.
You can't have it both ways. The reason jap cars DON'T HAVE TORQUE, is because the engines are half the displacement of american V-8's.
And how many stupid threads are there gonna be on this stupid subject?
If you want more torque?
Sell your stupid little torqueless hondas and buy a Caterpillar bulldozer. That should satisfy you. And put an end to these pointless threads
Mods please lock this. It's a useless waste of bandwidth.

 

Turbo

A turbo will increase your torque by 50%

 

Put your Honda on a freight train. That's the most torque your Honda will ever see.

 

Good idea about the bulldozer! how much do they cost, 0-60, 1/4. Will it beat my sir? Have you got one, do they come with... leather, a/c, pas, or anything else, where can i buy one?. Does anyone modify them? what size slicks can it take? oh and one more question, does anyone do track cover? i'd definitely need that.

 

oh and... i'd need a carbon bonnet, they have heavy bonnets i hear, well actually i don't but it would be a first.

 

u want torque??
get some strong rods and increase the stroke on the engine...
basically stroke it, raise compression, and balance the engine and you will notice a big difference

there are plenty of 4-bangers with torque. Drive a 98-01 Impreza 2.5RS . all they have is torque. oversquare engine with 10:1 compression. great down low. not so nice up high. at least not stock.

Do a LS swap. if that isn't enough, turbo it. There are no simple mods that will give you mroe torque. better response is all you can hope for with bolt-ons.

your advantage is weight, and possibly gearing depending on your model. maximize that. because no matter what anyone else has on you, you still have the weight advantage unless you're racing a lotus or a justy.

or you could swap out your hamster for a rat. they won;t rev as high, but they're mean down low.

 

You aren't going to get it with an NA 4 cylinder Honda motor.

Crank Torque is directly related to the amount of air/fuel that can be burned in one engine cycle and a little 4 cylinder is displacing about as much air/fuel as a 12 oz soda can. A little NA motor is not going to make torque no matter what you do to it, they make power by revs, and lots of them.

Best bet with a NA 4 cylinder Honda motor is get a b20 block with high compression and stage 3 jun cams.

i'd say he said it best. of course you can have a 4 cylinder with torque, but comparatively speaking it isn't as much as 'merican motors. the nissian sentra se-r has some nice torque on its 2.5l l4. i've only driven in one don't know the specs... but the k24 makes 160ft at 3500rpms i believe. just do some research into how these n/a motors are made specifically for low end power and redesign your junk to do that...or just buy a supercharger, or nawz y0!

Forced induction is the only way to gain a significant amount of torque with a small displacement engine. Specific combinations of displacement and geometry for naturally aspirated engines are limited to producing a certain amount of torque by nature -- you can only make so much before you reach diminishing returns.

Slap a supercharger or a turbo on that bitch and go to town

But this can all be changed if you custom build a 4 cyl from the ground up larger bore less stroke and small compression chambers with a well built head and some rich fuel maps and you will see a significant amount of trq and hp gains. So don't knock it unless you really try it.

yes but you can get a custom block made if you really want to go through all the trouble. and I think they make blocks liike that these days. correct me if im wrong

I though you increase trq with larger disp. and higher commpression. Guess not???

 

You know the old saying, "There is no replacement for displacement" if you want torque. B18C5, B20 Vtec, both should give you as much as the chassis can handle Or Turbo something.

Yes this is true, but there is two ways to gain displacement, increase the bore and increase the stroke of the piston.

In general, a proven way to increase torque is to increase the stroke of the piston, not by boring out the cylinder.

 

yes but if you wish to keep your High rev then you need to increase bore not stroke the longer the stroke the more force it takes to send those pistons back up.

Yup very true, thats why I love my b16. It has a 77.4 mm stroke so it can rev to 10K if I had cams that could make power that high.


If you increase bore, it will generate more torque, but not as much as if you increase the stroke.


That is why people build a b20 block to handle the extra revs because it has a longer stroke. Then you have to start thinking about R/S ratios and it gets a little more complicated.

 

yeah I havent got that far into my studies yet so you got me there with the r/s ratio but I do know that if you got into 4cyls for trq then you need to think again unless your willing to go through alot to get even stock v-8 trq.

if you want torque out of your NA 4 cyl, there is one option, boost.
