B20/VTEC 92 DA WHICH HEADER TO USE?
 

sup, I want to buy some dc headers for my ride. I was under the impression that all dc headers will give me the same results as long as its a b series header. My friend told me that I should get the Type R dc header. What is the different.

Any b-series header will fit on the b20 block, but depending on what your performance goals are you may want to select a different header.

If you definitely want a DC header:

DC 4-2-1 will give you some midrange power, but not all that much (2.25 in collector)
DC 4-1 for USDM 94-01 Integras will give you some decent midrange and high RPM power (2.25 in collector)

Your friend wants you to get the DC JDM (Type R) 4-1 for Integra Type R, this one is a 4-1 design, but also has a 2.5 in collector, which will require either a 2.5" test pipe or a high flo cat. I figure you are running a b20, so you will have to do some welding/cutting of your muffler and cat/testpipe anyway, so you might as well get the 4-1 JDM TypeR.

All 3 should cost around $250 or less.

There are lots of headers out there that make more power and have better build quality than DC: Toda, AN-R, Bisimoto, Hytech, SMSP, Comptech, etc but they tend to be far more expensive.

Just to clarify, none of the DC Sports headers have a 2.25" collector. All headers that are designed to bolt-on directly to "USDM" Integras (including DC Sports) have 2.00" OD collectors. The only headers that I know of with 2.25" collectors are custom-made pieces.

Yeah, you are correct, sorry for the misinfo. My overall point was you should get the 2.5" collector with the JDM Type R header.

I completely agree, especially on a 2 litre VTEC setup. Any other DC header would just be choking the motor. https://honda-tech.com/forums/images/smilies/emthup.gif

Don't forget you are going to have to notch your front crossmemeber to run the jdm 4-1 on a DA. I've been through it, it's not much fun.

anywhere that i can read about notching the crossmember? i have this same setup same car and everything.. need a header too! will most muffler shops install a header and make some custom pipe or whatever is needed to hook up to the exhaust?

you could check out the full race, z1, or place racing crossmember and see if any of them would fit with the 4-1 header, check out http://www.g2ic.com, I bet there is more info on this over there.
