i use a camry radiator, perfect fit if you dont mind cutting out original radiator support, hoses may be in the wrong spot for an a series though, check first

i raced with a gemini radiator and thermo fan and it never got over 80 degrees celcius

yeah but at least there is air flow when racing, nothing when stuck in traffic at 40 deg. Shroud helps heaps but i tend to just atch the temp guage (got a stock and aftermarket) stock one is a bit slow on the changes i tend to see.

Yeah, i might get her original one triple cored and then i can use the proper shroud again.

With my L-series im only runing a 10inch thermo, no engine fan but triple core saab rad, should be fine, not sitting in traffic with that car, it'll just start loading up i reckon.

so will any gemini radiator work or do u need an early or a later model one?

Corolla cs radiatoris about 70mm wider on the mounting holes which means you need to make a couple of small brackets if you dont want to modify the radiator pannel. I think their a little bit taller too but not enough to cause any trouble.
Inlet and outlet are a spot on match too.
Mid summer in Perth gets up around 40C + and I've never had the temp gague go over 80C.
