need advice on radiator

[stanger94gt]

need advice before my car melts!

undefined94 gt runs fine all around town, but when i really get on it for a minute or two, it over heats and i need water, stock motor, kenne bell 6psi, maf, throttle body, and full exhaust, 120k on car, the fan works, 180 therm, if anyone would buy a alum. radiator, which one would you go with

If a 94 doesn't already have an aluminum radiator, it can't hurt. However, I don't think that's the problem. Do a compression check on both the cooling system and the engine. You should almost never need water. Either you have a cooling system leak or a blown head gasket. Does your overflow bottle have any oil or oil residue in it?
