Need help with turbo

[91GTturbo]

I just purchased a 91 GT convertible with a single intercooled turbo. The car has been stored for the last 6 years after being purchased by a local collector. Driven less than 100 miles since he purchased it from the original owner. Car has 39,000 original miles. The previous owner was a 50 year old guy going through a mid life crisis who read about this kit and decided he had to have it.

I lifted the hood to inspect everything, and can you believe it was completely stock. The mass air, throtle body, injectors, I mean everything.

On to the questions. What size injectors, mass air and throtle body should I go with? I was leaning toward 30 lb injectors. If so, what king of fuel pressure should I be running? It does have an inline fuel pump.

Also, how much boost can I run on pump gas? I have every piece of paperwork since the turbo was installed, so if I didn't provide enough information, I'm sure I can find it.

Thanks for your help.
