koyorad on my 400hp Focus and never had over heating issues.
I replaced my 2010 factory Calsonic with a Kyorad 2807, there were lots of favorable comments on thenewx forum. 18 months later, still going.
I had read about people having good luck with the Kyorad brand so that's what I bought.
On my Miata with the factory flawed OEM coolant routing, I run a Koyorad 36mm aluminum radiator with OEM fans and it keeps temps a bit cooler than stock.
I changed out the intake (noise maker but I love it) then everything that connects so the turbo inlet and bpv, charge pipe and a bigger tmic. A engine that can breath will be healthy.
This specific spot fails on almost every subaru radiator i have worked on.
If you are lucky KoyoRad still has their sale going, I just got an aluminum radiator from my 97 legacy for $180
The radiator you could go OEM or NVA, but Koyorad is proven solid also.
For your turbo Baja, [Koyorad](https://ebay.us/m/yadARd) is the creme de la creme.
I went with a Koyorad radiator from rock auto and then I also replaced the inlet and outlet hoses with OE. A new OE radiator cap, too. Subarus are fairly sensitive to cooling system parts, so for any mechanical bits (cap, water pump, thermostat, etc) I highly recommend spending on OE.
