I will try to keep the code numbers for parts out of this to keep it simple. The transmission sits in the same location as stock all though I did use the unit that comes in the MK2T. In fact you could use two of the SC mounts, the far left and the rear will bolt right up. These mounts will not last under the power of the second generation motor so I wouldn't plan on using them for long, I didn't. The front tranny mount and right engine mount will take some fab work. A new mounting point will have to be fabbed and welded to the chassis for the engine mount. I am using the SC axels which seem plenty strong and the shaft diameter is the same size as the MK2 axels. You can also use the MK2 axels and carrier shaft bearing and  the outer CV joints from an SC. There has to be some fab work done to the frame to make enough room for motor movement around the alternator or you could go with the Celica All-Trac Alternator location. I had to cut a hole in my rear firewall to make room for the intake and then make a cover for it (shown below). After finding places to mount everything all you have left is the electrical. All the stock 88 gauges work fine with the 3S ECU and sensors except for the oil gauge. The MK2 comes with an idiot light and the MK1 has a gauge. To fix this it's just a matter of changing the sending unit over to the 4AGE style. Then all you have to do is make the 3S wiring harness and ECU work the the 88 Chassis wiring and relays :)
