I am about 70 percent done doing the same thing. mines an 85 t type. Exaust
Manifolds are different, Youll need a different crossover pipe as well,
Mass Airflow sensor is different.
You'll need to go over to Electric fans because the 87 runs hi and lo fans.
You can either modify your factory engine harness you have right now or run a new harness (I chose to run a new harness in mine)
Theres some retainers on the firewall right next to the Air conditioning box you will want to get for the back of the engine harness kirban sells them
If you didnt get the intercooler with brackets you will have to get those
The air conditioning lines are different and you will want to change them over (havent got to that part yet on mine)
Obviously an 86-87 Ecm
im sure theres stuff ive left out but off the top of my head.....
