^^ That should give you a general idea of what parts to get and somewhat in the order you should buy them in.

The thread title is extremely vague first off.

A turbo upgrade is serious business. There is at least $1000 to spend before even considering a turbo upgrade, which should be with some tuning as well. Anyone who buys a turbo to run at near-stock boost and can't log is doing things wrong.
