Stan, What Mark L. said. Your 1800cc bus engine is probably a type 4. They are a little heaver then the usual type 1 VW. It will need a force 1 front bearing the same as the type 1. You can find everything you need know about VW conversions at Great Plains Aircraft. Good people.
For the Corvair, definitely get WW's manual. http://flycorvair.com/products.html Also, check out: http://list.corvaircraft.org/mailman/private/corvaircraft_list.corvaircraft.org/2014/date.html Don't know where you are located, I have a good 1976 2000 cc VW type 4 you can have for the price of shipping. I'm in Charlotte, NC. Some have built a KR2 with a narrow fuselage, called a KR1 1/2. E-mail me with a ph# and time if you want to talk.
