Welcome, check the links in my sig - take a look at the one for bugeye owners, that would be you!
Oh and my car makes 280whp/wtq so I guess a vf34 would do it. Just about any upgraded turbo is going to be capable of hitting those numbers, just be mindful of the transmission.
Don't buy a turbo timer, they're a waste of money for our cars due to the fact that our turbos are oil and water cooled and have a properly implemented cooling system in place. So long as heat continues to rise and high pressure flows into low pressure your turbo will cool down properly. Still, most people here would agree it's not a bad idea to go easy for the last few minutes of any drive.
