Just as I said I would, I'm reporting back with more Ebay intercooler findings.
My core just failed me.
I somehow blew a hole or a crack in it somewhere near the drivers side endtank. I can not see where. All I feel is a huge amount of air coming out of it. I'm think that since I didn't really like how I had to route the piping in the first place, I will scrap the whole damn thing and just buy a kit with a better piping route.
It seemed to cool just fine, but I guess the weak link on mine was the material or a weld or something.
Now I need to find a kit out there, that is compatible with a 91 that still has A/C
