type 4 starter engine

[oasis]

Is it smart to consider buying a Type 4 engine ready-to-go (or close) for a short-term solution and as a basis for a long-term solution in my 1302, or should I just hold off and get the Type 4 built the way I want it when I am ready for it?

I am interested in a mild, easy-to-maintain engine in the 120-150 HP and Ft-Lbs range for spirited daily driving. I am guessing a 2056 or a 2270 is the most likely final solution. The car would see residential here-and-there driving as well as interstate driving.

If the answer to the question is yes, what do I consider when looking for that engine?

Would one of these be a decent basis? (If unknown, what would I ask to find out?)

Rebuilt 2.0

Turnkey 1.8

Another 1.8

I offered a typical array of ads one might find, although there aren't usually too many ads for complete Type 4 engines.

Am I better off looking for an engine that was already in a 356/914/912/411/412 than in a Type 2 (I know to avoid Vanagon engines)?
