Hmm...thought the '87 T cars were all powerd by a Buick turbo V6 or 307 Olds V8...
The short answer is, unless you do an entire driveline transplant, it isn't going to be easy. A real TR is a
LOT more than just a turbo on a V6.

The difference between a carbed car with a weak rear end and a fuel injected, turbocharged, intercooled car with a strong rear end is a
BIG difference. Short of buying a wrecked car and transplanting everything, it likely would be easier to just buy a real turbo T from the onset.
