Oil cooler orientation (Z1 cooler)

gozfast

I mounted my Stillen 25 row sideways just like you described. The supplied hose length with the fittings both pointed towards the filter side were longer than needed. I only had to buy one 45 fitting to replace one of the original 90's and shortened the longer hose about 5" and then they fit perfect. I also figured that the sideways orientation was the best compromise and only noticed a slight change of oil level due to drainback. The other plus is allowing the cooler to be mounted closer to the face of the condenser (~5mm) than the supplied kit mounting plate which increases actual pass thru airflow. I made four new simple brackets out of aluminum angle, one on each corner. I rubber mounted them to the upper and lower radiator supports to allow for expansion and vibration. My oil temps dropped 35 degrees with this setup. I don't have any pics of the install here right now, but can maybe post some in a few days.
