overheating problems
1. MY friends has a slightly modified 1993 MAZDA RX-7 (Touring Edition).
He has owned for some time but now for some reason whenever the car is driven for an excess of a couple of hours or if ran hard for half an hour it begins to heat up as much as 90 to 100celsius. Then when turned off the car can go up as much as 20celsius from there. Is this common in the third gen series? Car runs great other than this problem.
What could be the problem?

90 to 100 C is the norm for a stock rx7. the stock thermoswitch is supposed to kick in fans on high at about 105 so those are decent temps.
if he wants to get it lower get an FC thermoswitch which will lower the temp at which the fans turn on to about 95C.
or get a PFC and set it to whatever he wants.
it heats up after the car it turned off due to heat soak

heat soak is just heat being transferred from one medium to another, usually we used this term in reference to FMICs when they heat soak to the radiator.
you can't totally prevent it but you can minimize it by getting a vented hood and wrapping up some exhaust parts and your turbo
