Im about to buy a mugen header which is very expensive as anyone who knows mugen products knows. Anyways the header in the add says it fits B18C engine. I have a USDM B18C1 will this header be the same for fitment I just want to make sure before I take the expensive plunge thanks for now cranker

 

well i know the b18c1 is the gs-r motor and the b18c is the jdm type-r motor, i BELIEVE but don't quote me the blocks are the same so the headers should fit..

 

blocks are the same, heads are not, however, it still fits, where it meets the cat is different though.

somewhat of a waste of money too. the hytech, skunk2 megapower and other will be better performers for less cash
