Engine radiator MISHIMOTO or KOYORAD

No issues for years on mine. Turbocharged with a coolant reroute at 250whp. Had their products in my civic and diesel trucks in the past and had no complaints. Going on 10 years with their stuff.

Currently have one in a 97 for about 3 years, I don’t drive the car super hard so there’s no problems at all.

No issues with my mishimoto radiator in my 04 MSM. Kept the stock fans, however.

When this happened to me, I had to just bite the bullet and get the mishimoto radiator. Now my Z runs slightly on the cooler side and it’s amazing.

Mishimoto radiator, all under trays intact, vented carbon hood, dual rotary performance oil cooler thermostats, and mazdaspeed front bumper. She stayed a steady 205.

I placed the thicker koyorad in there and fixed a lot of issues, together with hood vents helped me getting my drift car cool.

I have the koyorad myself, bought it used. Spend some time sealing the nose to force all air through the radiator and you'll never have an overheating issue naturally aspirated.

Mishimoto is okay but it's fucking massive and requires more disassembly of the front end of the car to stuff it in there.

I despise those mishi radiators they take up too much space. Makes it hard to do anything on the front of the engine without ripping it out.

Recently got rid of the mishimoto radiator and went back to the updated larger radiator
