I have a 1989 coupe with silvia front end and a sr20det swap, the condenser sits between intercooler and radiator, is there any relocation kits or was to move it, or a way to keep it there and fix the problem. its hot here in GA. and the car starts to run really hot when i run the ac if im not on the highway and even then its still too hot for comfort.(me and the car running temp) lol. there seems just to be to much heat bundled in one area.

Do you run a low temp thermostat or upgrade radiator? That might be a good idea.

Due to oxidation radiators lose efficiency as they age. Any 10 year old rad can be improved upon with just a new oem unit. Carefil about aftermarlets which may weigh less and habe fewer thinner fins per inch.

Running wetter water and 30% AF ratio + 70% distilled water may help a few degrees.

The volume of coolant needs to be increased with an inlike aux tank to add 2,3,4 quarts.
