im doing a 2jzgte swap in my s13 coupe. i see people posting what brands they use on there swaps but not what car they ordered it for. ive seen a bunch of pic were people have cut the rad support to move the radiator foreword an inch which im fine with and ive seen ones were people have cut the neck on the engine and use a different radiator to eliminate the cross over pipe.
so with that being said what radiator are my options. as in like what car do i order for?

For the most part, you have 2 radiator to pick from SR or KA radiator for S13s. Only difference with the 2 is the location of the upper neck. SR is on the right side (which is where the stock 2JZ neck is at and use the cross over), while the KA is on the left side.

KA upper neck is on passenger side(same as outlet on the 2jz), SR is on the driver side. I'm currently using a Koyo KA radiator, FAL dual pusher's, mishimoto Tstat and a greddy radiator cap. I also had the upper neck modified so I can use a stock IS300 upper hose. So far I haven't had any major overheating issues:

I'm planning on using a stock KA radiator with altima fans or aftermarket electric fans. It should work well I think, and be slimmer than aftermarket thicker core radiators to allow better clearance.

Some people say the KA radiator isn't baffled on the top, so it allows the hot water to drop straight down to the bottom of the radiator...I haven't personally checked that however. It saves you a bit of room not having the upper neck run across and allows easier access to the belt/front of the engine.
