Headers?

Alright, I'm looking to get a header for my B16.. Will A 4-2-1 fit with no mod? I know you have to cut the front crossmember for the 4-1 style header..

Also, are B18, B17, and B16 headers all the same?

Each header will fit differently. Some 4-2-1 headers that merge up high will clear the stock 4G Civic crossmember, some may not.

B18/17/16 headers are not necessarily the same. The B18 blocks are longer/taller, so headers made for them tend to be a bit taller to clear the oil pan. B16 headers will bolt up to B18 heads/blocks, but they don't all clear the pans on the tall blocks.

But as far as the ports, they are the same, right?

yeah, the ports are the same.
Last year HaSport was selling a nice ass 4-2-1 header specifically designed for a B16 swap in the 88-91 chassis. It was guaranteed to clear the crossmember and have both o2 sensor bungs. I tried looking for it on their website but it's not there anymore. Give them a call.
