not yaris related, but looking for a cooling system guru - Toyota Yaris Forums

Without current oil temps, I'd say go with the biggest rad you can fit in the thing if you want to do oil-water cooling.

Figure you'll need to dissipate not only the heat from the water, but also the heat from the oil (which can be a bit higher).

C&R makes not only sweet radiators, but also oil-water cooler manifolds and some really neat oil valves, which can be used to regulate the flow of oil to the cooler.

If the rad that's on there now is at the limit, when this guy leans on it any further then the cooling system will really be stretched too thin (especially if bigger/better turbo's go in the thing).
