You will need to do the following to put the turbo on your car
You will need to fabricate a new Exhaust Manifold
Fabricate all the mounts & pipes for the intercooler (that's if you are going to be using a cooler)
Get the oil lines that would feed the oil to your turbo(s),
Make a dump pipe (from turbo to the exhaust
Make all the pipes to feed the air into the intake
If your engine is old you will need to rebuild it (throw in the forgies & get your rods shot pined & polished & get the bottom end balanced)
You will need bigger fuel pump, injectors, rewriten chip or a afftermarket computer, pressure regulator
If manual you will need to get a stronger box as the T5 will fall apart the first time you step on it
If auto get a tricked up C4 (get the conversion kit from castlemain Rod Shop or Mal Wood - Both are good kits & fit eazy)
If you are getting a second hand turbo(s) good cars to get them off are VL Commodore (T3 Watercooled with steel blades), Nissan Skyline (T25 but with ceremic blades. If you push it more then 12psi you will blow the turbo up), Nissan Skyline 2.0L (Has a T25 but with steel blades, Use 2 tubos & you will have very powerfull car).
Have you thought of superchargin... You can get a supercharger off a Toyota corona 1991 (It's an import so check with jap importers). The supercharger should cost you about $400 & all you need is the mounts fabricated & a belt to suit with the pulleys. It would be much cheaper then going for turbo setup....
Check this twin supercharged 302 ford XF ute with the toyota superchargers....
