I am curious on some parts, that will give me some great low-end power, im kinda worried about racing because it almost feels like I don't have enough low-end power?

My setup:

B20b4 stock
B16a Head milled 10thous.
GSR intake cam, B16 exhaust cam
OBX header(POS...open header) (Soon to be An-R haven't put it on yet)
Stock intake, with dirty *** K&N filter
Skunk2 Intake manifold
Competition 6-puck sprung clutch.
ACT streetlite Flywheel

Looking for cheapest possible way to make some minimal to great low-end power. Right now my mid-top-end is GREAT! I love it!!! But I am wanting more low-end power, any help would be greatly appreciated.

you already have a b20... unless you get into internals and bore it out even more, your not going to get much more low end torque. a CAI might give you some low end, but youll lose a little in the top end because of breathing problems. but regardless you should get an intake.

 

I think generally each part that you put on there effects the VE of your engine. As always you have to consider these compromises as you choose your parts. Again, generally; if you peak VE lower in the RPM range, your torque will benefit around that RPM range.

Not that any of this helps you by saying "install this part"; sorry.

 

changing the final drive helps alot too, it makes the motor feel more responsive

Probably the most noticeable change I've done is my ATS 4.9 fd.

The most effective way to get some more low end pull is with a shorter tranny, like an ITR tranny, or a final drive. You wont actually make more power down low, but you'll be able to use it more effectively.

 

Tune it with Hondata to get he biggest area under the curve as possible.


You think you have no torque? Try driving a b16...

 

Heheh you won't like it but I would recommend getting custom grind: High lift, low overlap/duration cams (like for turbo apps.) with high overlap long duration for VTEC.

Also, you can get/fabricate a dual stage intake (like a P72 with a B20 flange) that has longer/narrower runners for high intake velocity and shorter/wider sections for top end.

You can also get/fabricate a smaller diameter header primary to keep up the exhaust velocity.

Otherwise get the block bored as much as you can to get bigger pistons for more torque in general.

Another option is to get a stroker crank so that the pistons you have have more leverage on the crank on the powerstroke.

If your ignition system has a lot of miles on it you will get toque gains if you upgrade or at least refurbish your system. It gets more critical the higher the comrpession you go. Harder to jump the spark gap at higher temps and pressures.

All are not exhactly cheap. But that is what you can do unless you get the Euro accord with the H23 VTEC. That will give you more low-end torque. No replacement for displacement and all that jazz.

OR... you can run nitromethane. You will get lots of low-end torque but your engine probably won't survive long enough to get to the VTEC cam...

So essentially buy some Toda Cams.

 

well thanx guys.

 

And I am running a B16 tranny already, and it's plenty short for me right now, compared to my old motor.

I am looking for more low-end POWER not acceleration... or anything like that... just something that can help motor-wise.

Whats the difference? Both affect acceleration, but only one shows up on a dyno...I can tell you going from stock ITR gearing to 4.9 final drive made more of a difference than 10wtq down low could have, and good luck finding something to give you that kind of power under 4k rpms.

 

The surest way to increase low end torque is to increase displacement. This would mean increasing bore and/or stroke on your motor. The only problem is that you already have a B20. So displacement is already close to the maximum possible with a B-motor. You CAN resleeve and/or get a stoker kit. But you can't get much more displacement. And reliability will start to suffer as cylinder walls get thinner and/or rod ratio and piston speed reach unsafe (for the motor) levels. The only other option would be to upgrade to the H22A/H23A or maybe a K24 (if a swap kit is available for your car). The H-motors are actually quite cheap and provide LOTS more torque than B-motors.

The other possibility is to lighten your car. Lightening may not increase low end torque per say. But it does make the motor FEEL like it provides more low end torque (you can get an empty shopping cart going quicker than one that is loaded down, can't you?). And if you are willing to do so, you can always go with a lighter car. A CRX is always going to be faster and have the feeling of more low end torque with the same motor setup than an Integra.
