Im looking at a header choice but i dont wanna spend a whole crxp load. My choices so far are the hp racing header, the chikara hedman header and possibly a neuspeed. any ideas? The HP racing header was in the power pages of import tuner and was dynoed to ad like 5.8 to the wheels on a sohc honda civic ex engine, and its only 170$ in stainless, 220 in ceramic. I heard the neuspeed was better than the dc sports slightly. and I want the chikara torque step header but i think those are the expensive models. well anyway any help would be appreciated. thanks.
You have to determine what your final goal is for your car before you decide on what header to go with. Is this for street? drag? auto-x? Are you staying n/a or going turbo/sc? How heavily will you modify the engine if you stay n/a?
Don’t pay much attention to manufacturer advertised hp-gain claims, those are always tweaked and have a lot of tuning to go along with them.
Obviously if you think you might go turbo, don’t waste the money on a header, you’ll just be taking it off. If you do stay n/a, and you’re only mildly modifying the engine, stick with a 4-2-1 design. If you have a cai, consider stainless steel for its durability. If you only have a shortram, definately go with the ceramic coating (otherwise your shortram will be sucking in a lot of hot air = loss of performance).
If you do go with agressive cams, increased compression, etc. and you’re interested in having the car as a drag vehicle, then you should consider saving up for a large 4-1 design with a 2.5" collecter; otherwise, stick with the 4-2-1 design. For basic applications, DC& Greddy both make good headers, and they’re not too expensive. I’ve heard good things about the Chikara, but never known someone to have one.
If you have a 90-91 integra, you can also go with a 92-93 Integra exhaust manifold - that’s where the 10hp comes from (140 vs. 130). Good luck with your decision…
i understand that the 10hp difference between the 91 to 92 integras was more than just the header. It was a combination between the intake manifold, head and header. Not to mention the computer, the redline is higher, is the map any different?
