I run a 190 in my Honda v6 swapped Miata with a koyorad and it never overheats even in hot weather
I looked at what I bought like 165k and it was KOYO Radiator A1998 for $175 and I'm like 100k miles later and it still looks good. I just wanna change it for preventative maintenance since I'm gonna have my mechanic add the external cooler
I run a Koyo 37mm radiator... and I will hit 200+F under hard driving. Under normal driving, my coolant temps are in between 178-185F.
Koyo N flow. Only rad you’ll ever need. Even though you want to keep it “stock” the OEM style plastic crimped end tank design is a time bomb and should be avoided.
Koyo is definitely one of the best available as a stock replacement. They make 2. The n flow is a little harder to fit but is “better”.
Koyo rad is top tier, as I’ve used them on all my drift builds.
Held out for the koyorad and it's the same size as stock and went in with no troubles.
I have a koyo radiator in my na6 with stock fan on it and it has no clearance issues. Probably wasn’t necessary for me currently but I’m going turbo after I spend more time driving it na so figured why buy twice and just went for the koyo.
my valeo radiator didn't come with anything.. im just hoping it doesn't leak from that zone.
The problem I'm running in to is that the upper hose connection is positioned differently on the Koyo N-Flow/dual pass(RH020539N) and it's really close to the Q45 throttle body and attached TPS. I've already cut off the unused socket on the TPS which gives me more room but still not a ton to work with.
