wussup all. im doin a b18b ('93 b18a1 block, '98 b18b1 head) swap into my civic this weekend, and i just had a quick question for the teg experts. im lookin for an exhaust manifold cuz mind didn't come with one, and i found a dc gsr manifold. i was wondering if this would fit the b18, and if not, why? is there anyway i can use it? any info is very much appreciated, cuz if it doesnt work, im kinda screwed. let me know, thanks!

 

That would actually be a B18A swap. It's the block that determines it, because that's where the code is. They both use identical PR4 heads.

Anyway, the header will bolt to the engine, you'll just need the exhaust modified (lengthened or shortend) to bolt to the header.
