It is pretty straight forward- only the gearbox upgrade for a column shift gearbox is hard.
Remove your temp sensor from the vs and replace it in the bleed screw hole in the vt above the thermostat. Everyone says to tap a new hole but it is completely unnecessary. You can unplug and loosen the sensor to bleed the system, but always fill it through the top radiator hose to avoid a long bleeding process.
The passenger side engine mount must be swapped with yours for the mounting bracket for the ac compressor. Do this before fitting engine.
Also you swap the breather line as a VT has no charcoal cannister. I recommend keeping your exhaust headers too as VT manifolds crack on the passenger side, and you must swap the nearside to fit as bell housings are different on vs gearboxes, and its once again easier to swap over while the motors are out- swap eveything before fitting and use plenty of antiseize spray on the manifold bolts as they can easily snap and its near impossible to get the stud out if its in the car.
Also, it has EGR module/valve. I left it disconnected and it continues to run fine. and make sure you get an engine cover for a VT as they are different- exchange for your vs one.
If you end up upgrading your gearbox, let me know as I did a column shift so know every mod necessary. In the end though, not much fun! Recommend leaving gearboxes standard.
