    Hi I'm putting a 2 liter turbo. Just wondering if a 52mm aluminum radiator well supply enough cooling for track day and general driving or do I need to get a bigger one. And I'm running an electric water pump
    Cheers Matt

    Probably something you want to talk to your local radiator shop about. I've call Red Devil Radiators a few times with questions and they seem pretty good. I'm running a 52mm Alloy with a 4agte and it never gets too hot. I'd be looking at what the Nissan boys are running in their built cars to get a good starting point.

    52mm is probably overkill, stock evo's get around with a 32mm thick radiator and don't seem to have any issues up to 400hp (although the evo rads have a bit more surface area than an AE86 rad). Most AE86 alloy rads come in either 42mm or 52mm so either option would be fine providing it's getting airflow.

    With the forced induction 4age, you will find the use of an oil coiler more effective than the size of the radiator.
    I have an asi ebay radiator and find that my engine runs too cool on cold nights.
    Also have a Setrab oil cooler setup.
    Boosted turbo charged to 18 psi all the time and never experienced elevated temperature.
