I've seen some used Terminator motor/trans
for $6K-$8K. You might be able to find the wiring harness and EEC on there too. Might set you back around 500 bucks for that too. You'll will need a 8.8 from a GT and driveshaft, maybe around 200-300 bucks on ebay. The IRS from a Terminator could cost anywhere from 500-1000 bucks. SRA will be cheaper. Clutch pedal assembly on ebay around 125 bucks. Not a cheap swap but do-able.
