I was doing some work on my car this weekend, and thought about putting my slim line puller fans back on the car. (I have pusher fans on right now)
The reason I switched was I upgraded to the Koyo radiator and figured they wouldn't fit.
After using every cutting, grinding device I own, I can now say that if you have a Koyo in your S13 RB25 (mckinney mounts) you are not going to be able to use 12 inch puller fans. It simply will not clear.
I think you might be able to cram one slimline 10 inch in there but even that probably would be too close.
Anyway, I have seen a few people ask this question, so there is your answer.
