Omni-Cool (no longer in business) Intercooler (silver) and 460 FoMoCo Police Interceptor Oil Cooler (black) nestle behind Gen-2 bumper. Note stock cooling holes in lower bumper skin "chin."In this view, there appears to be plenty of room, but remember there's still a full-width, double-core radiator, large R-134a A/C condenser, plus O.E. dual-speed fan to  shoe-horn into this space. When it's all completed, the intercooler and oil cooler will virtually disappear, just what I want in a stealthy minivan.

Both oil lines and intercooler hoses route to driver's side. Both oil lines get spiral wrapped. Vertical brace on left is added to keep intercooler solidly mounted.
 

Everything was mounted without removing or modifying, grill, bumper skip, or composite bumper reinforcement.

Sandwich plate FoMoCo oil cooler just clears distributor and motor mount when properly "clocked." Oil cooler lines will be spiral-wrapped for chaffing protection. Tea-cup oil filter replaced with K&N Gold Performance Oil Filter.

Intercooler, as seen looking up through lower "chin channel" cooling slots in bumper skin.  Circular ring on right is new radiator mount, moved back to provide offset for oil and intercooler hoses.

Oil cooler as seen from ground.  Radiator donut shown, but not used on passenger side, as clearance for alternator required using original location.

This view is from below and is looking forward. It shows the new driver's side radiator donut and both intercooler hoses. The spiral-wrapped (black) hoses are the oil cooler lines. Some minor sheet metal was also trimmed to provide room.

Finished product is very stealthy. With a little black paint intercooler would totally disappear. I may open up rectangular bumper slots (a la 94-95-style bumper skins) if testing reveals need for additional airflow.

Note: While it would appear that the bumper impedes airflow to front-mounted intercooler (visible just below "Plymouth" logo), summer testing has revealed that sufficient air is drawn through the four, lower right-angle "chin" channels and the eight, horizontal "mail-slot" openings to keep air temperatures entering throttle body below 110 - 120 F degrees, under WOT conditions.

Modified mounting points for the original (R-134a) Air Conditioning condenser and original radiator and single (dual-speed) fan assembly.  (1990 SBEC controls the 1993 van's High Speed fan relay, while the 1993 van's Low-speed fan relay is controlled by Ignition switch, in effect the fan is always on "low", regardless of vehicle speed).  This arrangement works well, as the vehicle does a lot of stop-and-go, city driving. The 1990 SBEC increases the fan speed  whenever coolant hits 179 degrees F and vehicle speed is less than 40 mph or the A/C compressor is operating. A 185-degree F thermostat with bleed hole is fitted. Coolant temps come up quickly, even in winter driving conditions.
