Want to upgrade parts on a Celica racecar and want to do it cheap-Please help

[comradefks]

Ok guys here is my situation. I have a 87 Celica ST that I am using as a beater endurance racecar. I just finished at 13 hour race and my basic issues were mostly to do with overheating. Both the motor and transmission overheated multiple times in the race. These was no obvious damage done to the components but I want to upgrade the systems for the next race but since I am doing this on a tight budget I want to know if there are parts from other cars that fit on my car that will do the trick, i.e. used parts.

What I need is a larger radiator, preferably a dual core and as big as can fit in the Celica. A small radiator or something of the sort that I can use as a transmission cooler and rear shocks that might be OEM but from a new car. What I am thinking on the radiator is one from a larger car, maybe Camry or even a Toyota truck. It needs to have similiar connection points though. Also for the rear shocks, does anyone know if the current Celica's would have rear shocks that I could bolt up.

If anybody has done anything like this and has photos/write ups on it that would be perfect. Thanks for all the help in advance.

You can get more air through the rad to get better cooling. Like vent on the hood or another rad fan. Unless you rad is plugged up. You can add tranny cooler. Don't know if the AllTrac/GT4 rad will fit. Its a turbo engine so rad should be bigger.
