Is there another engine you can put into a 91 Integra LS other than the stock B18A1 without cutting engine bay or doing a lot of work If so what is it and if not what would you have to do to put a B18?
any bseries motor is a direct swap, b18a/b, b16a/b, b18c5/c1, b17a b20b/z, some will require different ecu/ jumper/distributor but all of these require no modifications to the chassis.
