2ZR Turbo Yaris

Is the fan really needed? Just simply having an oil cooler is a great upgrade.

I would think the only time the cooler would need to do it's job is when you're givin'er. There should be enough air flow through the cooler when your right foot is down, no?

I'd save the extra weight and money

You are probably correct. Definitely when moving it should be ok, but I was strongly advised by folks that turboed the 1ZZ auto to have a big trans cooler. I've already ordered the sensor/thermostat and this is the kind of design thing I crave. Haha. I would have done an oil cooler but that would be a much bigger and more expensive job to do correctly. I will install an oil temp gauge and if I see issues, I'll look into the filter concersion kit, sandwich plate and cooler.
