I have a 1991 Turbo 2. I have not yet running the car on the street because I dont know if the fuel injectors can deliver the correct fuel for the engine. The engine starts fine, but I have that preocupation. This is my setup:

I'm using an Electromotive Tec-2 programable computer. The engine have ported intake ports with 2 bridgeports on the front and on the rear irons. The housings exhaust ports are ported too. The engine is using stock
S5 turbo with ported wastegate and ported and polished throttle body. It have stock intercooler and the boost pressure is the stock one (I think is like 8 psi). I have 1 to 1 aftermarket fuel pressure regulator and is set to 45 psi with vacuum line disconected at idle. Right know the engine is using the factory 550cc fuel injectors on primary and secondary fuel rails.

The question is with the modifications that the engine have, what are the correct fuel injector size that I need? I can still use the factory 550cc's ones? Or I need to install another big ones?

 

720CC primary, 720CC secondary will be fine when using the stock turbo.

That turbo is WAY too small for a bridgeport.

 

que es la que hay guayama!!! 720's en los 2 yo estoy en las mismas!!!

"whats up!!! 720's on both rails I'm in the same boat"
