Depends on what you want from it. With only 26K miles, I would personally look into a GReddy Turbo kit for about $1400...which is cheaper than buying a complete swap and everything else needed for the swap. Cha Chi had kit on his D-Series motor and it hauled from what I've read. But if your not a big fan of FI, then a b16 is a good platform to start from...except everyone and there mother has one. If you had the money, a B18c1 is a really good platform to start from. It all comes down to what your looking for....a little more get up and go here and there..I'd say sohc and turbo kit...more drag racing and reliablitly...b-series and go from there.
