I have found a running RX7 car near my home for sale that I would like to
use the engine out of for my airplane.  The seller told me (via email) that
the car was not running right.  I asked him specifically what the problem
was and he reported the following....

"The engine fluctuates between 1000 and 1500 rpm and will no go over 1500
even with peddle to the floor. It only dose this every once and a while. I
haven't been able to find a cause yet. I have replaced the inline fuel
filter, checked all injectors, compression test, timing, replaced the
thermostat."

I know it could probably be one of several things wrong with the engine or a
component associated with the engine, but with this limited information is
there anything that would indicate an obvious major flaw that should cause
me to reject this engine?

Thanks,
Jeff

What year is it? Is it a turbo? Or NA? If so in both cases it could be
something as simple as a crack in an intake manifold rubber elbow.
A guy gave me an RX7 turbo because no mechanic he could find took the
trouble to take the intake system apart and look for cracks or leaks.

Probably nothing major in the engine.

Paul,

I can not find the ad right now, but I think it is a 1987 and assume it is
NA since he did not mention anything about a turbo.  He bought the car a few
years ago (I guess) with the intention of fixing it up, but he is a soldier
in the Army and overseas deployments have kept him from the project.  It
sounds like the car is in pretty rough shape and he is asking $500.  I
suspect this is not a firm price.

Thanks,
Jeff

Not a good year to buy anyway unless you just want to drive it.
Could be a bad sensor someplace too. The engine would be fine for mock
up or a 150 HP AC engine. 89's and later are better for high power engines.
Nice car to fix up and drive as the price is going up here in So Cal.
Nice ones are around $5000.
