Did you try this question in the civic forum?
My quick answer would be this. By the time you stroked the block to 1.8 and fitted it with a b16b head, you might as well just replace the whole thing with a B18. Plus, stroker kits are not ideal, cheap, or easy. Finally, "bolt-ons" are not trivial, so don't just list them as an afterthought. The quality of your exhaust manifold can make or break your NA setup.
