1) Will a Civic coupe exhaust match up to the exhaust manifold of the B18C block or does it require a welded flex pipe?

Usually it will require modifications. There are 2 easy ways to do it from what I have heard. Supposebly a header for a USDM ITR header will bolt right up. If not you can just have a test pipe done for a cat and have it done the right length or if you would like to keep your cat you can have an intermediate extension pipe put in between the cat and the exhaust.

2) Should be able to just use 99+ Si motor mounts for the new setup right?

not totally sure but you should/could get the integra mounts with the motor and they should work.

3) Any axle mods required (other than I have to swap out my old ones for teg axles)?

Nope not if yo are sticking with a B series. If you went H then you would need custom axles and a motor mount kit but your safe with the B.


4) Who has some great deals on complete engines? Wishing for JDM but will settle for local
