Well I grabbed a Koyo radiator the other day and put it in this afternoon. Well I discovered a few things. The application is a '98 Civic coupe with a B series swap.

1) Koyo does not fit like stock. I had to bend some sheet metal to get it to mount correctly. The problem is that the edges of the upper tank don't neck down enough and end up grinding against the car body. Ughh.

2) The stock fan will fit however, it sits far too damned close to the slave cylinder for my liking.

3) With a competch Icebox, the stock fan will not fit (even if you trim the shroud).

4) Depending on the fan you choose, the overflow tank may/may not fit. I ended up going with a FAL fan and the overflow tank definately does NOT fit. In the end (since I have no sprayers hooked up) I ran some line to the windshield fluid reservoir and now that will act as my overflow tank. Not too keen on the length of hose needed to do this so I will be changing this shortly.

Well just a heads up for anyone in the market for a new radiator.
