In need of help upgrading a few items…?

Hello, I just purchased a 1986 300zx Turbo - I am wanting to replace the wastegate, blow-off valve, fuel pressure regulator, and am going to add a boost controller. Can anyone give me any words of advice? I've never owned a Nissan, and I am not familiar with the engine layout -- If someone had a chart or picture locating the items I listed above, that'd be great. I receive the car thursday and will be ordering parts then too -- any speedy responses are greatly appreciated.
