Bus and 914 engine difference Options

[cal44]

Lads,
Not being fully versed on everything VW, I was curious if the a 2.0 Bus engine and a 2.0 914 engine are the same......Or, will a Bus 2.0 bolt right into a 914. Air cooled of course.

Also 1.7 and 1.8 while you are at it.

Thanks bunch.

Mike

Sarcastic remarks welcome, I like the humor

Bus motors work very hard,run hot and are more prone to dropping exhaust valves for that reason,all comments on the performance are correct,the saving in buying these motors is soon used up to get them to work,914 motors are still fairly cheap to buy .
I read somewhere the cases more often need line boring ,haven't seen this myself however.
I have a stock 1.8 bus ROW motor it has the larger valve heads and higher compression pistons, electronic ignition, twin Weber DCNVA's and freeflow exhaust,runs very well and makes pretty good power,the US motors were hampered by decreased valve size,small ports and low compression.
Not saying it can't be done but is it worth it ??
