All of the 2.3Ts had a turbo brace underneath, intercooler or not. It goes a long way toward preventing manifold cracks.
The intercooler that came on SVOs was physically different than the one on '87-88 Turbo Coupes. The SVO IC was taller and narrower, has brackets on both ends, and can actually be completely disassembled. The TC IC is completely welded. It's also wider, taller, and thinner, I suspect to gain some hood clearance. My TC IC has threaded bracket bosses on the front and rear, but I think they only came with a front support. They also flow all of about 25cfm more than the SVO IC, so not that significant. Either one is adequate up to about 220hp, but an FMIC is better even for stock engines.
