hey guys i looked around and couldnt find any info on what exactly would be the best headers for my 00' si. i know a ton of people go with DC mostly 4-2-1...but have heard that may not be the best way to go...any advice on any other brands...both ceramic or stainless????

 

jdm itr header

 

but i never saw the reason of replacing one stock part with another one..ya know?

 

You didnt specify it had to be non oem

 

o i know, im just taking suggestions on what other people know of...doesnt mean i have to agree with it. i just never saw the point of going from one stock part to another...but if thats a good choice, it is something i would look up.

 

you only have one header. so its not headers. no s. and the JDM ITR header is an upgrade compared to the stock si header

 

lol i wont respond to the last post...i would just be repeating myself again..but thanks for the input on the thread

 

if you can get your hands on one, i've heard good things about RMF headers

 

sorry still kinda new at this....RMF header?????

 

hytech replica

 

yea i was looking at some RMF yesterday, and wow those cost a bit more then i was looking to spend. is the hp and tq gain really worth the money??

comptech.

 

If youre just looking for a mild n/a setup than I dont think forking out the cash for a Hytech, RMF, or SMSP header is worth it. There is the hytech replica in the sponsor marketplace which is dyno proven.

You should do more research if you really think that its pointless to go from the oem header to the JDM ITR. Its actually quite an upgrade. Id prefer the JDM ITR header over any DC header, but thats just me. I do believe the DC 4-2-1 header comes with a 2.25" collector whereas the JDM ITR has a 2.5" collector.

well the thing is , ill be going boost within the next year or so so i really dont wanna spend too much. im running now AEM CAI, AEBS intake manifold, AEM pulley set and full cat Skunk2 exhaust....so i was looking for some more power till i went boost...i.e header or maybe some cams

Within the next year is not very long at all. Just save the money youd use on a header and cams for the turbo setup. If you insist you can grab you a JDM ITR style header or a Megan Racing header temporarily so you should spend around $150 only. They both will perform similar to the real JDM ITR and the DC header will probably not gain anymore. The reason theyre cheap is not because of performance, but because of quality. Since youre boosting sometime soon, a cheap header that will perform about the same for hundreds less will be a smart choice.

And ditch the idea of cams. Youre also going to need valvetrain, cam gears and a tune along with that to make any use of them which will put quite a hold on a turbo setup.

 

JDM ITR 4-1

 

ok, thats what some people have told me...just hold off till i go boost. but the turbo would get held back power wise even with a complete cam change with the valves and springs also???

 

There are cams made for all motor applications and turbo applications. Youd be losing if you threw in turbo cams into your n/a motor and youd have to take out the n/a cams after youre boosted. CTR cams should do fine for a mild n/a setup or a turbo setup so you can throw that in there BUT youd have to build the b16 block if you wanted to get in the CTR cams efficiency range anyways so either way youre probably going to have to stick to similar hp numbers so the block will hold up.

 

ok well since i am going turbo soon is there anything i can put into my engine now that will give me gains that wont effect my engine when i boost or hold it back at all???

A 3-inch exhaust will be a huge upgrade for your turbo and it won't kill your stock setup. It would be utterly moronic of you to get a header when you're "going turbo soon". A header won't add jack **** to your current setup, regardless of how expensive it is, so I suggest skipping it and putting the money you save toward the purchase of turbo components that don't suck.

 

yea i know the 3inch is better for the exhaust but theres no way im replacing the skunk2 with the money i paid for that...so ill just be bottle necking a bit once i go boost

Sounds like you didn't think very hard before you started buying parts. Are you 16 by chance?

FYI, on your b16 you don't have a header. you have a exhaust manifold, 2 different things. so going from a manifold to a header is a upgrade.
