I have a koyo in my B14 with dual slim fans, one pulling and one pushing, mounted on each side of the radiator.
Only running a t28 for now, but this is the setup I will be sticking with when going to a larger turbo. Should fit a top mount turbo with a log mani with no issues.
All you need with it is a Nismo thermostat and you should be good to go. Ideal setup...
