Before we deluge ND with questions about bolt-on turbo kits, we had this
discussion in both May and October of last year.

Here are a couple of excerpts from email messages that I had in my
archives:

Now, I did some inital looking into the possiblility of doing a bolt-on
conversion using just the exhaust manifold and turbo with some
additional fuel enrichment (black box style).

The conclusion that I came to was that w/o any sort of knock sensor, and
with the higher compression ratios of the N/A engines, you'd only be
able to run ~4-5 pounds of boost before temperatures and the threat of
detonation would start to cause you serious problems.

I decided that if it were to be done, a full MC motor transplant would
probably be the better solution.  I don't know of anybody, who once they
got a taste of a boosted engine, wouldn't want to turn the wick up just
"a little bit more."  On a converted engine, this is asking for trouble.

The MC motor itself is just better suited to use with a turbo with the
oil squirters for the pistons and the sodium filled exhaust valves.

HTH!
