I am in desperate search for low end for the H22. Since my car is a daily driver and I dont "cruise" in VTEC, I decided to improve the low end as much as I can N/A without any concern for VTEC nor high end power. I have a few questions:

1. Would a 2 1/4" testpipe and mandrel bent piping (w/ no resonator) leading to a straight thru high flow muffler be too freeflowing on a stock internal H22 (good high end but loss in the low rpm band)?

2. Which would contribute to better low end? A cold air intake with 2.75" piping or a short ram intake with 3" piping?

3. DC vs Greddy vs Stock.. I've noticed that the stock header looks similar to the DC header I have on (in size as well as design). I've also read that the Greddy header produces more torque and hp. With that in mind, does that mean the Greddy header produces better low end or just a better peak hp/tq?

4. Can you list some things that would produce better low end, that I didnt mention, as well as little DIY tuning I can do?

I want my apple to be an Elephant (forget an orange),...OK?

Both of those are poor choices for low-end torque. The stock airbox will make for more sub 4000rpm power than either of those options. The AEM accessory pulleys are also good for low end HP.

if you are looking for low end, you are looking at the wrong car. sorry to burst your bubble, but unless you have loads of cash laying around you will not make the H22 a low end torque monster.

Basically, I/H/E focuses on top end power (this is obviously not true for all applications, but for the most part).

There are few things that will help your low end. Your looking at drastic things, like boring out the motor or buying a supercharger.

I am not trying to bash your ideas, I too, would LOVE some more low end torque. However, i have decided to abandon that idea and focus on mid on top end, since thats where i will be when i am pushing the car anyways.

Anyways, the H22A is a big block chevy compared to a lot of other honda motors, ever driven a stock civic? heh

 

he could try a .5" exhaust

 

Can try some AEM power pulleys...

so would you say the stock exhaust produces better low end than say.. an Apex'i or Greddy catback?

 

aem power pulleys, just a filter, and JRSC.

</TD></TR></TABLE> thats a good size exhaust. but dont go over 2.25

good size exhaust for low end or mid to high end?

whaaaa..all this misinformation..first of all the greddy header makes good midrance, your peak gain is only like 6 or 8, but it has a fat midrange, a CAI will make more power and TOURQE than your stock airbox, and since the numbers are higher, its got more low end, and getting a small exhaust for a slight imporvment for low end is stupid, also, im running 2.5" piping Apexi N1..and Mysecondaries are open all the time, so i suppose my LOW END sucks huh, but actually my low end rips, off the line and my first 2 gears absolutely run..i run high 5's in the 330 mark at the track, pull consistent 2.1 60s, and run high 8 sec 1/8ths...get a set of cam gears, they can adjust your power band around, and make you some good power

 

JRSC = low end torque

 

if you want good low and mid range power, id go with a...
1. K&N drop in air filer in stock box. CAI will have shitty low end, but good top.
2. Greddy 4-2-1 header with Highflow cat.
3. Any 2.5" cat back exhaust or even stock would be fine.
4. Clutchmasters lighened flywheel, gets you moving faster. easy to drive to.
5. V-AFC tuned.

 

using the stock intake is just shitty, your not getting anything extra, and the miniscule youd get inst worth the upper power youd be losing out on.....and as for the lighter flywheel, i think this mod is only good for road racing, a stock flywheel will yeild better 1/4 mile times iMO, CAM GEARS are the best low end mod you can do, becasue this will allow you to adjust your calves opening and overlap...but lets be honest its a 4cylinder i mean the h22 makes good tourqe for what it is and especuially compared to the b series ect...but i think hi questions are due to him losing his recent races to his freind off the line, says he gets beat off the line, you shjould have no problems ripping 2.1 60 fts , LSD isnt even nesecary to acomplish this, launch at 5k slipping the clucth, once you learn how to do it right i guarentee you that your freind GSR will have no chance off the line anymore

 

PreludeRacer023 - Nice times, nice motor I am looking to piece together a setup similar to yours along with a direct port nitrous setup. Would you reccomend a 2.5" cat back? I was originally thinking of going with a 2.25 setup but i havent researched it much.

I was originally going to get a greddy sp but i think i will get piping from kteller8. Do you think 2.5 would be the best for my application?

5. sell your car and buy a V8 camaro. want low end? you need higher displacement egines. when you bought your honda you should have thought about it. too late now.
there are some measures you can take to boost the low end a little, but they are not worth the money and they wouldn't make sense because you'd be suffering up top where it matters the most.
for a stock 2.2l four, prelude's torque does just fine. try driving a civic DX or even better a CX, then you'll appreciate prelude's torque a little more.

thanks, yes 2.5 is good thats what im using, im adding an NX wet kit, 80 shot, getting my car tuned finally, and off to the strip with ne radials, i should see 12.7ish..which will make me very happy, other than that im adding thr Hondata IM gasket, IM, and TB, adding those with the nitrous should net me some mid 12s..only other things im doing is new paint job, same color, brakes and suspension, im very content with the speed, and the nitrous will mainly be for the big boys, ..

I am pretty sure that was just a typo. But what size piping is recommended for the best low end without sacrificing too much high end?

 

Everyone says 2.5 is overkill on h22s but preluderacer is pulling the best times and thats what he is running? is there any gains to be had by switching to a 2.5 inch exhaust?

 

What size piping do most recommend and why to a stock muffler?

I plan to get mandrel bent piping to a stock muffler for daily driving purposes and unbolt it for days when im at the track.
