You want, if at all possible, an LSD equipped tranny. Sometimes there hard to find!!

A B16B is a Civic Type-R engine and are very rare and expensive. B18B is a non-vtec Integra engine I just got my B16B a week ago. The only reason I picked this engine over the B18C is that it's rare and I got the entire swap for a good price
GO WITH B18C. As stated a good engine N/A or with FI.
