What aftermarket radiators do you guys have on your A/T coupes? I'm looking for an OEM replacement as my end tanks have cracked. I also have a Vortech kit installed so I'm wanting something that will fit? I was looking at the Mishimotos but have been told there are problems with fitment and require cutting? Can anyone confirm? I understand the Koyos are for M/T only and I will need to get a tranny cooler, but more worried about the fitment especially with the piping that goes from the s/c to the cooler that goes across.

 

PWR are good they have a built in oil/tranny cooler. There is a new company out called Forged Racing I have seen their rads they look really well built.

 

You can try the Mizu radiators. That's the one i am looking into

 

I have a few friends with Koyos, one of which has a Vortech. I'm getting ready to install a Koyo in my Sedan (5AT) as well. You are correct about needing a tranny cooler since it doesn't have one built in.

 

Can you help me out with how to hook up the Koyo to 5at? do i just go straight to tranny?

 

Two year bump................... I just did a radiator it's easy and self explanatory.

 

^^Which one did you end up going with?

 

The transmissions cooler lines hook up to the fittings on the radiator.
