what type of headers are the best for a 240sx?

[JPz92x240]

im lookin to buy headers for my car,i just dont know who to go with.
will any type of headers do jus fine ?
which brand gives the best gain and the least amount of probs?

[TheWolf]

usually the most expensive ones give the best gains and least ammount of probs. Somewhere in between might be the best value for dollar but that's like asking opinions on a part for these engines that doesn't do a whole lot.

[orion::S14]

On an S13, headers are a miniml gain...the stock manifold is not that bad.

On an S14, where there's a cat at the exit of the manifold, and the header replaces all of that...there's ~5-6rwhp gains to be found.

So with that said...HotSHot is the best. Yes, they cost $300, but they are th best.

But I'd spend that same $$$ elsewhere on an S13...like I said, the stock manifold isn't bad. When you get to the +150rwhp level...then go for the little extras like a header.

Least amount of trouble if in cali greddy. I have one for sale hit me up

[i20ar]

so on the stock s13 the header flows pretty good? replacing it would'nt free up some gains? jw..

[orion::S14]

^^^ Yep, stock S13 setup is NOT bad.

Maybe a 1-2rwhp gain going with a HotShot over stock...not really worth it for the $$$.

Now, on an S14...5-6rwhp at least is expected...the cat is VERY restrictive, and you can still use one under the car to keep it smog friendly (stock, there is an empty shell there as a resonator...looks like a real cat, though).

Greddy is the way to go, best of luck finding one. I was lucky enough to pick this one up for free for my free labor at a friend's shop. I've only seen two for sale in the past year.


4 into 1




They go for 300+

[j00ni3]

don't go to the 4-1 one setups. sorry tre... but ka's love the 4-2-1 setups...

i have had the best luck with that... i got my custom at a shop hehehehe

[tre]

Depends on how you're driving your ka

I"m all about keeping it around 6/7k until i can push the rev limiter back.

4-2-1 is more for a low end, street application.

plus 4-1 = better scavaging affect

OMG, search much?

Brian not here to make fun of, but the 92 s13's made almost 7RWHP with the DC sports.....
Although DC isn't a hotshot scavaging and flow are much better since back pressure throughout a high performance header is reduced to a minimal. Nissan stock headers are designed for maximum backpressure for the EGR system.

When JWT (hotshot) headers were stop being sold. I belive DC picked up on them.

Tre not here to clown (or humiliate), but the Greddy was discontinued for numerous reasons.
It was a stainless steel header, which if you know anything about welding, welds don't hold to well to heat tolerances.
It was a 4-1, which the KA is a low rev torque engine.
It didn't show significant HP results on the dyno.
One of Greddy's highest return products under warrantee so to speak. It wasn't one of Greddy's better business decisions.

Turbo manifolds are probably the best, and give the greatest hp boost.

I'm serious. x2
