I have the smaller spearco style intercooler. I kept my oil cooler in the same place. My intercooler was a little bit of a pain to mount, I welded exhaust brackets onto the bumper mount. The aluminum ones it came with were flimsy and broke when I tried to bend them into shape. It was also tight (real tight) to get 2.5" pipe in there so I recommend getting some 90 degree bend silicone couplers to be able to route the pipe coming off the turbo and then another to dip the top outlet down enough to connect to the pipe running to the TB.
Good luck, its a project, but well worth it!
