Will a 1995 ls header fit on a 1998 B18C1?
Will a 1995 Rs header fit on a 1998 B18C1?

and would the RS and LS use the same header?

 

nope, wont fit. the LS header has 6 ports while the Rs header has 4 ports.

 

doesn't ls and rs have the same motor so how come the header is different

 

He's joking. There are no 6 cyclinder integras.

 

oh i get it now hahahahaha....lol i was like whats he talking bout

 

morning bump.

 

They are exactly the same manifolds....it will bolt directly up to your block but not up to your exhaust. 94-99 gsr's have a slightly longer exhaust, by 4". You'd have to bring your exhaust in to a shop to have them make the necessary adjustments.

 

Thanks for the thorough answer man. I don't think I want to mess with my exhaust since I want to return back to stock if anything should happen to my vision cat-back system. Why do they have to make it so difficult? Bastrds.

 

The bigger question is why you would even bother swapping one for another

 

The answer to that questions is simple. I have the chance to get a DC 4-1 Header from an LS motor. I wanted to swap my oem B18C1 header with the DC header from the LS. Objective: Get more power.

 

USDM dc header is poo. Save your money.

 

My girlfriend's brother threw a rod and consequently is doing an H22A swap. He was going to sell me the header from his LS for around $100 if it fit up. I figure I couldn't go wrong with that price. Since the header seems to be more trouble than it's worth, I'll be posting his intake, header, exhaust, in the for sale section if and when the swap takes place.
