Need help with turbo
 

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.

I would say 30 or 36 lb injectors and any large aftermarket mass air meter. To handle fuel and spark chores I would have a reputable performance shop dyno tune it at around 8 psi with a wide band O2 sensor and a custom chip. No FMU, just a wider pulse width through the new chip.

Hey exgmguy, whats this about wider pulse width on the computer chip. I'm going to get my car dyno'd soon and I have 30# inj. and 8-10 psi vortech with 6:1 fmu. I'm looking at different shops right now. Any shops around here? I was thinking Detroit speedworks or the place across from Total Performance that Lidio uses.
