Different Types of B16a Engines:

Choosing the Correct B16 Series Engine is based on multiple factors, How Difficult do you want to be? Or if you are paying for it.. I guess it doesn't Matter.
The 2 types of B16a's that come to my mind are B16a OBD 0 or B16a OBD1 and well of course the ever illusive B16b..better know as Civic Type-R.
Unless you are paying to have the swap done there any many parts you need to buy to make the Engine Swap a Success. In general there is a basic list of parts you need to complete the swap.. and it will be based on the car you are swapping into as well. The Core basic parts is the Axles, Shift Linkage, Engine Mounts and ECU. You will have to decide as well on if you want to keep the ammendities or not.. some people choose to drop the power steering or Air Conditioning. This was not ment to be a guide but a short overview of the things you will need to look out for..Good Luck!
