wassup guys, i just had a question about which header would be best for my car. I have a 92 cx hatch with stock b18b and was wondering which header would be best for my setup. I was thinkin about a jdm itr header but i'm not sure if it would fit the port holes. Also a dc 4-1 header maybe? So i was wondering if you guys could give me some suggestions on which header would be best for performance and ideal for my set up.

Thanks, John

EDIT* the motor is a 94 b18b

i have the DC 4-1 header, and i can say that it helps where the LS motor lacks...TOP END.....i could feel a slight difference after 6000rpm......i like it alot

 

ive always had the greddy header.....i had the 4-2-1 one piece. Its a top end header.

People will argue with you about this however, a search for thegreatheadertest will reveal Dyno's from the same car with a lot of different headers.

 

so my best bet is going with a DC header? how much hp would i gain off the 4-1

very helpful site, thanks

 

get an LS header it saves you the hassle of having to lengthen the pipe.

 

Give Header Tech a Call...

 

would a jdm itr header fit?

im pretty sure all b series headers are interchangeable...meaning the exhaust ports are all the same. but the lengths are different from a 1.6 to a 1.8, but since you are talking about an LS you should be cool, so yes i believe an ITR header will fit....correct me if i am wrong anyone

 

how is the performance from an jdm itr header compared to a dc 4-1 header? im still not too sure on which header to purchase

 

bump

I'd almost think that a JDM ITR header would be a great header for an LS engine. It would let it flow, ut not too much. About the give headertech a call thing, ha ha, yeah right. $700 what!? damn nice, though

extra $350 for easily 10 more horsepower on a built motor. I`d say it`s well worth it. That`s much cheaper than cams and tuning.

ive got to agree with ryan on this...
we spend a lot of money on other things just so we can get 3-4 hp, but if the header tech has been proven 10...why not add the $350.

 

thanks for all the feedback guys, i guess i'll go with the itr header. Is there anything else i need to make it fit ?

I have the DC 4-1 (non JDM) on my LS teg (B18B) and it definitely helps with the topend. Unfortunately, the 4-1's hang lower than the 4-2-1 headers and mine is all banged up now. Assuming you're in NYC by your sn, you know how bad the roads here can be.

 

yes, the roads are not smooth at all
