Where to start. Just from the pictures:

No hint on the exhaust. Will you need to weld on lip?
Divided turbo, undivided manifold. Look at the provided gaskets.
You'll have to drill and tap for a signal source for the wastegate.
No idea on the spring rate for the wastegate.
Generic turbo.

Meh....

 

The welds on the Manifold are ****. My buddy got one for a temp fix and running 13 psi.....say goodbye welds.

 

Ebay intercoolers are generally good if they're sealed propperly. It's a metal welded box...only one thing can go wrong with it.
