Headers

[35suren]

hey guy i bought headers OBX and my friends said those arent so good i been looking around but still dont know which ones to get.....any ideas....:hyper:

[!Zar!]

Woah.

Engrish.

Running a header is pretty pointless imo.

Just grabs more attention to your engine bay. One of the first things cops look for.

If you must, check out hotshot. I believe theirs was carb legal.

Too bad they're not in business anymore. Shot up the prices of used ones too.

[35suren]

man..........so theirs no point

[Okinawandrifter87]

Yeah please dont go ricy on us with headers!!! =0)

[Phlip]

one bank of cylinders...
one header
for what it is worth, you'd not gain a WHOLE LOT out of one honestly, and would be best to just skip that idea altogether if you're planning to boost/swap later on down the road, just save the money.
If you're looking to wring all the NA power you can out of it, then try and find a HotShot

I had an OBX header. It was great. I replaced my hotshot header with it. It was better quality then the hotshot as well and MUCH MUCH cheaper. Didnt feel any difference in power between the 2. The HOTSHOT header rotted out, then obx is stainless steel. My buddy also has a OBX header on his Sentra se-r and its realy good quality however there this weird bird chirp coming from somewere now, maybe gasket, bad flexpipe, i dunno. But the header for my 240 was perfect.

First time Ive ever heard someone replaced their hotshot with an obx and was happy with it.

I have a header and no exhaust. I like it much better w/o the exhaust, seems like it has more power. If you have an exhaust it will be loud as hell, the reason why I took off my exhaust is because it was too loud for my 10 month old son.

Hahahahahaha WTF?

Headers are a waste of money... Enough said.
Why do you think HotShot went out of business? And OBX is garbage!

First of all Silvia and OBX should not even be in the same sentence... =) (IMO)

[ladiesman8527]

do what you want to do, but a header is kind of a waste. by all means, if you want a nice looking stainless steel header to brighten up your engine bay, grab an obx header. i had an obx header on my first s14 way back in the day. it fit great, didnt leak, and looked great. just dont expect anything magical to happen performance wise.

S&S headers are pretty good as far as I've read. NOT SS... s AND s.

But if you dont think a header will help, you need to get off. When you equalize the exhaust pulses and smooth out the flow for the hot exhaust gasses, you allow more air to enter and leave the engine, which means HP and more importantly, torque. Equal pulses are especially good if you have a turbo. its like having a neat organized line at McD's instead of a free for all first-come-first-serve. And if your doing something stupid which requires a cop to look under your hood, him or her seeing your header should be the least of your concerns. Besides, you should use exhaust wrap anyhow, because your stock heat shield prolly wont fit. Get some black wrap. Problem solved.

I dont even have an obx, i got the cheapest one i could get from ebay. The exhaust manifold swap has been proven to make power, whether you think its worth it or not is another story but it does make significant power for the price (200 or so). Also, stainless steel is lighter than cast iron and you will lose weight for this mod, another plus.

I changed to a header, hi-flow cat and exhaust all at once and it definitely made a difference.

You can make more power with a larger MAF (N60) and SAFC in your glove box then you can with headers. If you have a KA with SCV's remove those too. Sleeper status with a high flow CAT (make sure the high flow CATCO is 3way, almost all Magna Flows come 3way). When you take it in for smog just put your settings at 0 across the RPM range on your SAFC and pass smog visual, dyno, sniffer with flying colors.
You could get a retuned ecu but nothing passes smog better than a stock ecu.
I have a DC sports header on my KA some smog techs care, and some don't. Some ask for a little extra something in the pocket if you know what I mean...

[fantasya98]

Interesting^ so you're saying a larger maf and retune w/safc makes significant gains? How much would you think? Also, how does running a larger maf make any diff.?

I will let the pics explain.. The only reason why you make power using a larger MAF is because the stock MAF is too small. You don't even have to change fuel settings, the only reason why you would need the SAFC is to adjust the voltage to the TP scale.

STOCK s13 MAF 59mm

STOCK TB 65mm taper to 60mm bore

The whole idea is to turn the intake system into a very long velocity stack that will continually compress air to the plenum. That doesn't work when the MAF is smaller than the TB. The s13 MAF is the minimum requirement for intake flow. If the MAF was larger the engine could compress more air increasing HP, and throttle response. I'm also not suggesting that you get anything ridiculous like an N62 which isn't needed for N/A applications, or a MAF that would be too large and wont create enough velocity to cool the hotwire. An N60 is all that is needed.
The other great thing about this setup is that it is a good prep for boost applications as well.

Back on topic now.....
