yeah it's on the left for an SR, so you would have to run a long hose like krayton said. but it's better to get the KA version cause you can run a short hose and still have a bigger radiator then stock. Since we don't have much room up front it's just be a pain to run the longer hose. Plus with the shorter hose you will get a much cleaner look in your engine bay.
93RPS13- YOU can get one from

http://www.phase2motortrend.com/cooling.html (exact link to the radaitors) you can compare the 2 versions. The SR is 2 mm bigger not big enough to make me worry about it.
So i guess the RB20DET radiator outlet is on the right side also like the RB25DET??
