If you've got the space and mechanical know-how, you may want to consider getting a used engine and rebuilding it to the specs you want, that way when yours goes you've got one ready to swap in. That's exactly what I'm doing with mine.

You may also want to look into an Air/fuel converter. I'm currently running an apexi VAFC on my Acura and am in the process of programming a "lean burn" mode into it. The older models (for our older vehicles) can be readily found on eBay/forums for a third the cost of a new one.
