I was looking at radiators in Ebay and saw the info on both of them. They both have the same dimensions, the bottom mounts will most likely need to be modified for fitment but not a big deal.

I have a s13 in the yard that is in somewhat unbuilt condition, as well as a parted out MKIII shell. I don't think the radiator is bolted into the S13, so I could probably test fit it for you. They are both really close to the home of quite a few aggressive bumble bees. I can do it at night, while they sleep.

Did you see a comparison of the inlet/outlet. It seems to me that the S13 uses a smaller hose. You really wouldn't want to compromise your flow.

Beeeeeeeeeeeeecareful with the bees man I dont want you getting stung by any of them. By the way the inlet and oulet in our cars according to the koyo copper radiators are 1 and 5/16 and the s13 is 1 and 3/8 just 1/16 bigger no biggie.

OK, I have just done a test fit, as the bees have gone to bed for the night. It looks like it can be done, but there is one hurdle that would have to be done to make it work, that I don't quite know if there would be a consequence to. The outlet on the top of the S13 radiator is on the passenger side all the way at the end. That is opposite to the Supra, but I'm sure you could make some sort of hose work, but it would have to do a complete 180 to mate up with the thermostat housing. Or, possibly a hose could come straight off and just do a 90, but my shell has no motor to see exactly where the thermostat housing would be.

As far as fitting, it seems to fit the hole better than the Supra radiator. You would have to do something as far as the lower posts. Both posts sit on the outside edge of our stock holes. I think you could actually just weld a small half loop onto the stock brackets. As it is, the radiator sits on top of our brackets just fine, and height is perfect. The S13 radiator also tapers off at the top on the passenger side a little before where the stock upper brackets go. It shouldn't be too hard to drill and tap a new hole a couple of inches over for that.

I left my camera at work today, so I will have to take some pictures tomorrow.

The radiator that you test fitted is for the KA24de engine, the one that we are lookin at will have the inlet and outlet on the same side that our mk3 supras do. Look at the pic on the top link, and thanks for taking the time to do the test fitting. In interested in buying one and doing a write up on it but it will have to wait about a month I just ordered me a front mount check it out.
