They all fit!

However, some might argue that the 3.0 is about the largest you want bolted to a stock 914 trans. Some say a 3.2 is still ok.

Will these be carbed or FI motors. For the 3.2, you will need to find a place to keep the brain. CIS is a little easier, but sometimes folks mod the engine lid to fit the CIS unit.

My favorites are 3.0L carbed motors. Looks and sounds just right imho. Of course, given the greater HP adn TQ, you might need to worry about tire sieze (flares), brakes, stiffer suspension etc. Might also need to plump up some additional oil coolers if not already there. Its my recollection that the stock 2.0 6 in the 914 runs about 10 degrees hotter than when the same motor was in the 911. Living in Vegas, heat might be an issue.
