I am about to upgrade to a Koyo N Flo and from the looks of it doesn’t look like it’s gonna fit. Has anyone done it? If so did the brace behind the radiator fan have to be removed or modified?
I have a Blitz FMIC and a regular Koyo, but I think it's the same thickness/size as the N Flo.
The radiator DOES fit. I had to make most of the brackets for my FMIC since I got the kit used, and I think some of them had to be slightly different due to the size of the radiator.
The brace that the battery bolts to and the stock IC bolts to may have to be trimmed, I made a custom one when I did my FMIC install just to do it.
In general, there is room to make it work, you may have to bend, fab, or modify brackets to make it fit well.
Threw it in just to see and it does fit however modifications are gonna be needed. The brace that the battery is held up by touched the fan shroud. When set st the correct angel when straight up it fits to however the radiator no longer goes into the lower mounts that hold it steady.
Dale would you happen to have a picture of your bay?
Thank you for the photos! You guys are always really helpful and I appreciate it!! From the pictures you listed it would seem that you dont run the brace that is typically behind the radiator fan.
That brace is just there for things to bolt to, it isn't structural. You can make your own out of aluminum, I got a piece of C-channel aluminum from McMaster-Carr, trimmed where appropriate, put in some rivnuts to bolt stuff to, and had it powder coated.
Realized I hadn't posted up any pics, see attached. I have a few close in shots.
I have the battery mounted like the manual says, it's a Miata battery on a stock FD battery tray. You turn the battery sideways and cut out the front part of the tray. It's unconventional but it's rock solid. I did have to do some minor trimming of the fan motor plastics to fit.
You can also see the custom aluminum cross bracket I made. I got the raw piece from McMaster-Carr, it almost was the perfect length as it came (3 feet or so?).
How you guys bent the oil cooler lines to fit the radiator fans? in the instructions it says to bent them closer to the engine but I tried to push them as hard as I could but all they do is flex all the oil cooler assembly and it just doesn't bend.
There's pretty much no easy way the radiator is going to fit with the R1 stock oil cooler lines. When I installed mine I replaced those lines with braided lines and AN fittings, just replaced the lines and used the same stock oil cooler.
I don't think they accounted for the R1 type stock dual oil coolers. If you have a base with one oil cooler none of that plumbing is there.
