I turbo’d my 1985 BJ60 a while ago to get a little more out of the 3b.
Regular driving was great with no heat issues but I often tow and BC is mountainous I found I wasn’t able to really utilize my turbo due to heat soaking on the 1/2 hour long 6% hill climbs. my wastegate was set to 10psi but I had my fuel barely turned up to keep from reaching dangerous egt’s on those long hill climbs and only really ever saw 6psi boost.
So something really needed to be done to properly utilize the turbo, it had to be Intercooled. I planned to front mount an Intercooler like normal people do but really wanted to do something different in part because I like how clean and open the engine compartment is and didn’t want 8 feet of piping clogging it up.
I started looking around at vehicle’s on the road with top mounded Intercoolers and hood scoops. Some Subaru foresters have a nice looking subtle scoop I was thinking I could cut and weld into my 60 hood.
But! I wanted this scoop to be functional so I had to do some testing first. I picked up some yarn and taped 5 inch lengths from the front of my hood to the middle where a typical hood scoop would be like the Tacoma’s non functional scoop.
One big problem i found because the 60 series hood doesn’t have much slope to it the yarn would flick up and wave around from the hood in the middle indicating a low pressure zone. Low pressure would cause no air to push into the scoop or worse yet flow backwards from the engine compartment out of the scoop negating the purpose of the intercooler.
However the very front of the hood was very obviously a high pressure zone with the yarn laying very flat. So I thought about this problem for a while, how could I ram air from the front to a Intercooler.. One day driving for work in town the solution came to me via a newish GMC Sierra HD that rear ended me, just a light bump. They have a similar flatish hood as the 60 series but with a nice looking intake right at that perfect high pressure zone.

Works great! I can now roar around at 10psi boost all day without any heat issues and at a safe EGT range.

Felt like incorporating the tow hitch receiver into my bumper to gain a couple inches clearance on the 60’s bubble butt.
