I was thinking of replacing the header for my H22A which already has the original jdm header on it with a Megan 4-2-1 header, so I would like to know if the Megan header would be any better than the stock header the H22A comes with?

Car has 2.5" exhaust system from the front to the back already.

Thanks Guys.

Okay the gains depend on what else you have done to your car. If you get a megan atleast get the COllector modified to a 2.5.

 

Don't mess with the Megan header unless you need a cheap replacement for the JDM one. I would be surprised if the Megan was any better at all. Even if you do the collector mod you might as well do it to the header you have and save money.

 

It will be worth a few hp.

 

i didn't buy a Megan header, but i bought an eBay one. was basically the same as the stock jdm except the walls wernt double lined and the secondaries were a tad bigger if i remember right. besides that just the stainless finish. I made decent power with my eBay header so for the 76 i spent on it .

we made 190 whp on a dynojet with I/H/E JDM H22 with the 70 dollar shipped ebay header!! we've been running the cheapy meagan header on our H2B crx due to lack of funds! still ran 11.7 with that header.. collector modded to be 2.5"..

overall i'd go with the 70 dollar cheapy header. its better than stock.. and like i said we made 190 whp with that header crome tuned otherwise stock motor..

 

Im thinking of doing the same thing to my prelude, but i have a half retarted question, h22a headers fit jdm h22 motors?

It should as long as its one set of headers......

As long as it doesnt have the ATTS attached JDM h22 and USDM h22 are pretty much identical, pretty much

 

So my final question is, do you guys think that ANY of these aftermarket headers would be better than the stock header on a jdm H22A?

Thanks Guys!

 

I would recommend not going cheap on the header at all. If you are trying to make any power at all with an N/A build the header is where you make your money. There are places where you can cut corners but the header is not one of them. Start saving a good head will cost you from 800-1200 big ones

 

In that case I might as well save a little more and go turbo ...

for 70 bucks you can't go wrong with the ebay cheapy header. like i said we made 190 with it. we are even running it on our all motor crx running 11.7's.. not the best but it will make some power. and you aren't building a full race motor. believe me this header will make just as much or more than a DC garbage header. for only 70 bucks. they are pretty sturdy too. no cracking and seems to hold up after a few years of running it. sure as hell more sturdy than a 400 dollar DC header!

an alternative if you want to fork out more money is the camp 1320 header. makes great power. but its a hell of a lot more than 70 bucks!

 

DC sports, megan, OBX, and all other headers you find on ebay with random brand names attached to them are all stock replacements. The header that comes on the JDM motor is pretty good to begin with.

Stock H22 header has very small pipes. i still think for 70 bucks its worth it to get a cheapy header. it will give you more power over the stock one.

 

Okay I talked to an installer at a performance shop today (they mostly work on muscle cars though) - he claims that those cheaper header's are becoming more and more popular because people are beginning to realise that they are mostly paying for the name.

That may be true - I mean the guy does this stuff on a daily basis - but I think I am gonna go with your opinion h22crxpwr and change it - you are right about the stock pipes being small. When I had my DOHC ZC even the header on that motor (Aftemarket HP-Racing Header) looked bigger than the stock H22A one.

BTW, do I get one specifically for a JDM H22A or will the USDM H22 header bolt right up?

Thanx Guys!

Most after market headers are better than stock, for h22's at least. USDM and JDM will be the same to bolt up to.

That couldn't be a worse statement. With the exception of the ITR, s2000, and maybe the RSX, the h22 factory header is quite a quality piece, when compared with the stock offerings for the h23, all the older b series, and f series pieces, there is no comparison.

The ebay or megan or whatever &lt;$300 header you buy will be shiny and cheap, and if you're a smart buyer, it will probably last, but confusing yourself into thinking that you're making a worthwhile performance upgrade with a cheap header on an H22 is a mistake.

 

I bought a Megan Header for my Lude and I ran a 14.2 with just a V2, the megan header and test pipe, and a S2 cat-back. I don't really know what the difference between the two but if I can buy just an exhaust and a intake and run a 14.2, I am happy.

for 70 bucks i'd rather run the header with bigger runners. where the 2 peices of stock header come together it gets really tight and the material and look of the stock header is crap.

70 bucks and it looks better and i've dyno'd 190 whp on a stock jdm h22 with cheap *** h22 header p28 crome tuned.

210 whp on stock H2B with pro 1's and cheap *** header. and 240 with built block and the same cheap *** header. not that we particularly wanted to run this header but its all we had. now its a custom header..... but we still made good power with that 70 dollar header.

and it ran 11.70... at 115 mph...

 

spend 50 dollars and put a 2.5" or so collector on the stock header....

better quality header and you dont have to worry about it cracking.

your talking about peak hp man and on some dyno that not everyone dyno's on.

i've tuned a stock h22a to 186whp and 162ftlbs on a stock header with 2.5" collector.

doesnt make much sense to spout off some numbers that dont represent anything.

show me your inner diameter measurements and I'll believe that. Remember that the stock pipes are ovular in the 2-1 section, so get out your math book and figure up the cross-sectional area.

Spouting numbers and times with nothing to compare to does nobody any good, as Blake said.

Because you don't dyno on it that means its not a valid dyno #??

Dyno'd at whitfield racing by chris (on a dynojet) motors usually see 165-185 for stock h22.

dyno'd the car with stock header and made 184 then i put the ebay without the 2.5 collector mod. just out of the box and put on and it made 190. and the customer ran it for the past year and a half with no cracking.

i'm sure this gets back to "you get what you pay for" right.....

hey you go do what you want.... use a stock header or whatever you have.

you know better with all the power you've made... and times you've run..

 

h22crxpwr, you are probably right. Last night I met this guy who was friends with a buddy of mine and he has been running a cheap ebay header on his D16 for over a year now with ZERO issues what so ever.

So I asked him how that header was going and he said it was just as good as the first day he put it in. "You get what you pay for" ??? Ehhh, not always I think. I think I am gonna give the offbrand ebay header a try and let you guys know in this post how it worked out...

As posted earlier, you simply threw out a number of hp that you made, with nothing to compare to, and this, i hope you can understand why, is worthless.

The fact that you're posting that now makes me question its validity, it seems that would have been the first thing you would have posted. Post the sheet.

You're taking this too personal bud. If you take a look around this forum, you'll find that I did a review on the cheap $70 ebay header as a good replacement for when you're not able to find a good replacement header for whatever need. I have one on my prelude right now and it has been more than fine for about a year now.

For what its worth, I've been there, done that before. My opinion on a $70 eBay replacement header has very little correlation with my knowledge on how to make real power from an engine anyways.

You seem to like tooting your own horn, but so you know, 11.7 quarter miles in a CRX aren't as impressive as you think they are.
