Overheating Problem
#1
I am buying an 88 n/a RX-7 from a friend. He has had it for a while and just recently it has been overheating.
I am pretty new on rotary engines so I was wondering what are some of the basic problems when overheating on RX-7s
thnks.

You don't want one that's been overheated. Rotary engines do not take kindly to overheating.
Running a little hotter than normal and overheating are two different things.
Which is it?
If it's running a little hotter, replace it with (and only with) a Mazda OEM thermostat, and flush the rad and system and refill with fresh coolant.
Also you'll have to figure out when it's running hot or overheating (at idle or cruise) to help determine the cause.
It could be a number of things.

I've over heated my motor a few times on the road course and I'm still running the same ported motor I built 7 years ago...I run 20psi too...Some motors can't take an overheat issue...It all depends on who built it... If its running hot buy an aluminum radiator...its the best mod you can do to a rotary.. You will have to inspect everything Like the guy above said
