So I finally had to get under my FD for the first time since purchasing her to change out the starter. I Went with the 2kw from RX7.com. While I was under I removed the plastic shield under the radiator to check general condition of everything I could get to. This looks to be an upgraded radiator but since I haven’t done much work yet on FD’s I’m not sure. I’m guessing it’s upgraded since it’s all aluminum. I was hoping someone could at least confirm it’s not stock and if they recognize the brand. I saw no markings. The car sat for a good 8 years and was rarely driven when I got her. The previous owner did upgrade items but had no records. Thanks for any help 🤙🏼

 

It's a koyo. If you clean up that end tank, or get a pic of the top tank, you should be able to see if there's a divider - and whether multi-pass.

 

Yep, looks like a Koyo. It will be stamped on the top tank but you would have to take stuff apart to see it.

It's an excellent radiator, the previous owner did you right there.
