Question Koyo or Mishimoto Radiator?

i have been hearing mixed opinions on Mishimoto radiator. some work great while some dont.
On the other hand i havent really hard bad things about Koyo.
WHat would people recommend between the two? Im only daily driving the car but it is fp black running at 30psi. i do want to keep it cold.
are there any other radiators in the same price range that i should consider?

I've always ran Koyo when it came to upgrading, but I've seen cars running Mishimoto radiators get absolutely hammered on and not overheat. A lot of folks here in AZ are running Mishi rads in their track cars, and even in the summer they don't have problems.

If you can afford the Koyo, go for it. The quality is a bit higher. If the Mishimoto is what your budget allows, then go that route.

The koyo is definitely a higher quality piece than the mishimoto. The CBRD is better than both of them. There is a ton of info on the CBRD on this board. Search around

I haven't seen anything that shows koyo any better then mishimoto performance wise to justify the higher cost.

My mishimoto had pretty good fit and worked well, the warranty support is also very good.

CBRD is in a league of its own and if I needed a slim full size I'd probably pick them.

At the time I needed a new rad I went Mishimoto because funds were short. Its been great, paired with their low temp thermostat car runs real cool no matter how hard I drive it (even in summer). Mishimoto=good bang for your buck if you ask me.

yup no issues with my mishimoto other then a radiator cap goin bad, but 1 day shipping from mishimoto directly and i was back on the road. No complaints no overheating issues even in 100+ ambient temps. I like it, plus lifetime warranty and accident coverage is nice too. haha

those that are saying the CBRD rad is the best I'd like to know what that's based on? I hope its just not on the fact that its double the price of the others mentioned.

in my personal experience, the OEM rad is very good at doing its job on a bolt-on sub 350whp car. by 'very good' I'm referring to being able to keep coolant temps around 190* in the middle of July with over 100* ambient temps on the race track for 20-25minutes at a time. Not only that, but the recovery time is awesome too. In the last year, with the OEM rad on the track, I think I've seen a peak of 202* coolant temps as recorded by EVOScan.

I just tossed the name into the hat, I have no personal experience running any of the radiators in this thread.

I do know that CBRD products are top notch, so I felt they should get honorable mention.

I am a firm believer that you usually get what you pay for.
