[FlyRotary] Re: Need quick help - found 3 different
13
but I just found a
place that has three RX-7s - a
pre-'86, an '87 and a post-'89. I can get the 87 engine
(complete with ECU,
he says) for $350 USD. I didn't ask a price for the newer
unit.
Is there anything in particular that would make the
post-'89 more useful
than the '87?

I
would probably skip the pre-86. The 87 is fine, as is the
89. The 89-91 had lighter rotors, and higher compression,
though it won't matter that much. The bigger question would be
whether either of these was a turbo engine. It would also be
nice to know why the cars were in the yard. For example, a
totaled rear end of the car would probably indicate that the engine
was OK at the time. A good body would probably mean the engine
was toast. Either way, you'd want to rebuild it, but it will
likely be cheaper if the engine was good when it was
scrapped.
Give
us more info, and we can help you make a better
decision. Good luck.

I disagree skipping the pre-86 as they are good
engines.
They have 3mm apex seals and the o rings are in the
aluminum rotor housing so you don't have the problem of the ring
groove rusting and braking away, also the side and center housings are
interchangeable with the 12A which are a dime a dozen in the case you
need one someday.
There are two types of pre-86 13B's, a 4 port with carb and
a 6 port with injection and the porting is better in the 12A center
housing than in the 6 port so it would be an advantage to pull a
switch if you had a 12A center housing.
