no clearance issues with the Koyo radiator. the intake pipe is tight on the tranny if you got the anti surge cover. i also have a slim fan.

 

the turbo flange bolt/nut tend to back out. make sure you get some nord lock washers. seems to be a common issue with some other that have this turbo.

 

A friend just installed his atp3582r version of this. It is a little laggy but pulls like crazy up top. I'm on the fence if I should look for the HkS 7460R, Tomei arms, new fp54 , or swap to a hta71. I'm just glad there are still plenty of stock frame options still left.
