welcome to the board.

i'd say go with a 13B simply because 12A parts are only going to get harder to find whereas 13B parts are still readily available.

Get a good running/low mile motor from a 2nd gen S5 (89-91), open it up, give it a nice port (bridge or aggressive streetport), some new seals, and slap on a well tuned carb.

Or, if you're feeling adventurous, a 13b-MSP (Renesis) out of the RX-8. That's a whole other can of worms though.

Between 13b and 12a?

13b.

More power, more parts readily available.

take it from a first gen owner, if you can find what your looking for engine parts wise, your spending near as much for the 13b. plus i hear the 13b though, its slightly larger and more efficient being fuel injected, is lighter than the 12a block is, i've been thinking about doing a 13b swap on mine.
