Where are you located?

I have all that stuff, as well as tools, manuals, etc. If you are relatively nearby that makes it easy.

You'll also need a D24T intake manifold to go with the turbo and turbo header, unless you have plans for using the NA intake with home-made charge air piping.

Headgasket selection is based on a measurement of piston protrusion from the block. However, you have other considerations here as well to think about before you jump into this, such as:
>>How many miles on your bottom end? Compression and oil usage before it was overheated? Easy to start when warm? If you are starting with a tired engine that has been overheated (not good for the rings, and if it was hot enough you can damage pistons and bores as well), then you might want to consider giving it some attention or at least examination before putting it back together. Would be no fun to spend all the money and time and have it not perform like you want it to.
>>The D24T bottom end is different in several key ways from the D24. The turbo motor is set up to handle higher temps and pressures that come with forced aspiration. Putting turbo components on a non-turbo bottom end isn't automatically a recipe for trouble, but you have to use it carefully and be starting with a good D24 engine for it to not self-destruct fairly swiftly. If your bottom end needs help, then getting a complete D24T engine may be a better way to go.
>>You'll want to use the updated MLS head gasket. Look around in the engine section here for more info.
