1945,
will the intake/cooling bracket fit an OEM radiator? My bracket is likely different than what you have and in fact it didn't fit the CBR radiator bolt holes well, so I'm not sure of the issue, but at the time I wanted this thing running so I "fixed" it and made it work.
Firejeep,
I've certainly seen guys builds online where they are running OEM, but I've heard of issues and I simply just don't know enough to say it'll be no problem. If I knew it would fit and the fan bracket used in the axis kit fit, I'd say experiment, but I think it's all designed together. Of course, like I said before, I have no idea if my fan even works, so maybe it's worth the experiment, but if you drop somewhere in the neighborhood of $20k, 10% additional will seem like nothing if you can have the project fired up and driving around without too many problems. With a build like this I made sure I had even more funds built into it for emergency use, which I ate into pretty hard when I decided to get tires/wheels/gauges, etc. My amazon/off-road vendor orders look pretty insane in the last 12 months.
