what would be a good header?i have some ideas but ,need more input.thanks

 

a lot of people like the kamikazi header.

 

They like it because it has short fat primaries to a large collector. I makes the best power with jrsc.

I have a used one laying around if your interested in it hit me up.

 

I had one but I sold it....I wanted to roll a jdm type r header,but i was told it was a mainly na header.I wounder if it will put out good power?thanks for the replies

 

Kamikazae all the way, make sure you get the one with the 2.5'' collector.

 

kamikaze header makes the most power on a jrsc

 

So many people on this board say the Kamikaze header works best with the JRSC. But when I called Jackson Racing, they said use the DC JDM 4-1 header. I would like some concrete info on this subject. One other thing is I've heard thar the Kamikaze header leaks @ the head & or the collector of the primaries. But that is just a rumour. I don't know for sure.

they say the kamikaze is the best...read his tech articles..I trust his judgement

 

I used a Kamikaze and it made a huge difference when I popped it on with a Carsound cat.

Plug :I have that combo for a GSR for sale

 

Kamikazi on the JRSC I installed on a Prelude

JR says a lot of questionable things.

JR says a lot of questionable things.</TD></TR></TABLE> OK, I can believe that. But I know this guy that installs JRSC's all the time. He says to stick with the JDM DC header. He says the Kamikaze is bad about leaking & that they are not made well. Personally I've never inspected one up close for myself. But if they are so bad, why do so many people use them?

 

people run kami because the peak power gain is good, but they didn't look at the whole picture. if you run jrsc over 12psi, kami is a great choice. as larry did as his good old civic. try to stay away from endyn, product he is selling isn't the same ones as the one on his civic... stepper pullies are crap, so are the info on the site...

dc 4-1 is good with jrsc for a pretty good upper area power gain. it has good fit and qulaity, which is more favorable for that few peak hp loss. but who stays at peak all day? switched from a loud kami -&gt; 3 in carsound -&gt; thermal 3 in, to nice and quiet dc 4-1 -&gt; 2.5 in carsound -&gt; 60mm Apexi World Sport. Lost 1 hp peak (which can't be taken for sure, since runs can vary) but overall from 4k and up, there were more area gain. (area is a pretty acurate deal).

 

The one i had ,and that i sold .When i was looking at the welds there nice but,the welds were starting to crack.but when it was on the motor the guy i bought it from ,he said he made great power....so no one thinks the jdm oem header will do great?
