So I have a question that maybe some fellow EP3ers can help me with. So far the only modifications I have on my car are the following: Injen intake from a RSX type s, and a Magnaflow catback exhaust. So my question which would be more beneficial to get first, a race header or the hondata reflash? I plan on getting both eventually, but I only have the funds to get one right now. So which should I get :shrug:

I'd say raceheader cause your butt will feel the difference for awhile..
Then when you get around to where you forgot how the ep ran and you're not thrilled with the raceheader, get the reflash, and then that raceheader will sound and make alot more ponies in the 7K + rpm range.

personally i say save up and do them both at the same time...that way the car is running the way it should be, producing more power and tuned properly.

just save up a littttle bit more, grab the header, wait until you can afford the reflash..do em together.

get the race header then skip reflash and go for k-pro.

This is your best route imo.

If I recall correctly, Hondata does not reccomend that you run a raceheader with Reflash anyways. I believe the combination of the two tends to run lean.

Running a RH for a long period of time with an unmodified ECU will make it run lean. The reflash will help it some but in the long run you'd need kpro to make it safe.

will an o2 defouler help it not run as lean?

Well what the defouler will do is trick the ecu into thinking the catalytic converter is still in the system. You are just taking exhaust flow away from it so it sees that there is less flow going past that particular sensor thus still has the catalytic converter in there, when in reality it does not.

How do you like that combo? Is it leaning out too much?

I'm split still. I was leaning RH because I could still use regular gas. But with reflash you're still emissions legal. I'm just going to wait and save my money because I can't use either with a k24 swap down the road.

why not an ITR header its basically a 2 piece race header that has a cat on it

Some words of caution: Mixing a Raceheader with the Magnaflow cat-back can get "sport bikey" above 4000 rpms....

same here. No signs of running lean or anything.

I have been running the same set up for a few months now. Also i heard the problem with the reflash and a rach header is with the newer model civic with the k20z3 not on the k20a3's

what i'm hearing is "should i get a rh and then get light 500 dollars on fire and then spend 900 on kpro because burning 500 bucks didn't really do it for me"






racehader then KPRO

Its not $500.. and you can still upgrade.

correct me if i'm wrong, but the reflash WAS around 400-500 dollars, and even when you "upgrade" you're still spending another 400 or so dollars. am i right or wrong? because EVERYONE i talk to who got the reflash ALWAYS regrets doing it because its never enough, and they end up dropping more coin on k-pro

na. Im pretty content with what I got. Im done with engine modding. But I/h/e and kpro will not be enough to feed the need of most on here. Honestly if u wana be in the modding game and ur gona mod an a3 then u better look into boost. If ur just doing boltons with kpro then seriuosly what are u gona beat? Maybe a type S with boltons? Some older Si's or maybe some single cam hatches? The list of what an a3 with boltons and kpro can beat isnt an impressive list.

But to OP go with the raceheader first then kpro. Then once u realize a bolton a3 is slow u can atleast get a JRSC and slap it on there and be somewhat satisfied

Listen to everyone in this thread and get a RH first. You should probably buy my Jackson Racing RH I have for sale in the classifieds. It is hands down one of the best RH's out for the EP3, especially because it is Stainless Steel. JR no longer makes this header.

I have to care. I am a new father so money is everything yo. Also I want to ask how much of a difference the race header makes on the stock ecu. I have never gotten a straight answer. I am looking into the reflash but maybe the header will do until I get kpro. I really need the extra 900 rpm right now though. 6800 with the 6 speed gear box leaves you really wanting more.
