Tracy--
Thanks
for the clarification on running without the turbo.
What
is your professional opinion on the “mix & match” aspect of
spec’d parts during a rebuild?

The 86 - 88 NA engines were 9.4 CR engines, just .4 more
than the 91 turbos. I have no idea how that silly rumor about how
turbo engines sans-turbo would be a dog. It is, of course,
nonsense.

To Everyone—
We have both a 13b NA (unknown vintage—80's?) and a '91
Turbo 13B engine and are just beginning their teardowns, both allegedly running
but internal condition unknown. Would there be any problem running
the Turbo engine (BUT NOT with the turbo setup-- AS IF it were a
NA engine)? Is it a "stronger" engine than the NA? Would
it need a different Timing setup? Would there be a compression problem
running it sans turbo? (Hearsay has it that it would be a
"dog".) If some of the individual parts spec out to be better
in one engine but not in the other, would there be any problem/advantage in
"mixing & matching" the various parts in the newly built up
engine, i.e., rotaries, side plates, eccentric shaft, etc? We would
appreciate your inputs. Thanks!
