one question couple of people have told me that i need diffrent headers to swap a k20a3 into my integra just wondering if thats true or not.

 

I dont know if thats true, but your gonna have a sick a$$ integra when your done.

 

thanks Im gonna do the full vtec swap later down the road

 

Yes, a b series header will not fit on a k series. K20a2 would have been a better choice but your a3 will be nice too!

 

Yes, and its "header" not "headers"...there's only one...unlike a v8. But yes...the k20 sits backwards compared to the b-series, so you will need a header for the k20. I believe Comptech makes one for the RSX, and you can use it for your swap...not sure about how it connects to the exhaust, but you definitely can't use the b-series header. When you plan on swapping it?? K-series are wicked...expensive, but wicked! BTW, don't get the k20a3 unless you are gonna swap a type s head on it.
