Ok, I've searched a long time, and I see that the 350z Radiator doesn't bolt right up. I know that the fill cap is on the other side and a longer silicone hose is needed. I know the top is where modified mounts are needed? Or the core support needs to be grinded somewhere?

Is there a DIY somewhere? Or detailed information of what is needed?
Also, on after market slim fans, how are these wired up? Im just looking at some X2 14" eBay fans. Thanks for the details and specifics. Looking at the Mishimoto.

 

There is no DIY as far as I know, because it is a PITA!! If you want a new radiator, get the Koyo. I do not have any experience with any others, but with some cutting of the core support down below, it is possible to make it fit. You will just keep having to cut and seeing what you have to do to make it fit. We also trimmed down some hoses to make sure they didn't rub against it. See my thread:

We didn't use the top mounting points, instead we just took a longer bolt and screwed straight into the top of the radiator. You can see that with the washers and the longer bolt. That worked fine. Make it way easier, and you don't have to modify the radiator.
