I have a D16B5 VTEC out of a 99 Civic GX california spec car with 14k miles (Carfax report). It runs on natural gas. I didn't do the extra research to see what was required to make it straight gasoline powered.

Not sure if you just have to swap intake manifolds or what.

Put it next to a D16y8 and you can't tell the difference.

if you want it, it can be yours. It's been on a crate in my garage for 1 year now, clean from top to bottom and in dry storage.
