ok heres what im planning for my s13 turbo set up, im going to relocate my radiator to the bottom of the engine bay, kinda angled, and have the intercooler sit flat with the head lights, kinda like a top mount i/c but in front of the motor instead of on top of it. now i done some research and found out that the FC stock radiator is already slanted, and what im wondering is what years did the radiator come like that? is it all FC's? are the Na and TII radiators the same? also is there any aftermarket radiators that fit in the stock location for FC's? TIA

 

Great, another f'n newbie. All FC's had the same slanted setup, but as far as the actual radiator I'm not sure. If you want a good radiator, get the measurements you want first and have one made up for you. It'll probably be cheaper than buying one already made up for another application. http://griffinrad.com/ makes some top drawer stuff from what I hear.
So, are you t/c'ing your present KA24E or are you going SR20DET? Have you been to freshalloy.com? They might be able to help you better there.

On a side note, wwscc.org has info for the 9th in Everett.

 

The stock FC radiator is one of the few components on the car that is a piece of junk. I agree with the previous post in that a custom Griffin is the way to go. I'm not sure why you are asking for a stock replacement aftermarket radiator if you are not going to put it in the stock location, but Fluidyne makes them, although they are not quite as good as the Griffin in my opinion. K2RD sells one:
