Default i would say yes...

the stock intake manifold will work fine, it's only flaw is its restrictive nature. port it out to get full potential.
as for the injectors, i'm sure they will hold 15psi boost, however that doesn't mean they will be spraying enough fuel in the cylinders.

by the way, what kinda car/engine are you bolting this onto?

They will "hold" fine, but will not supply enough fuel for above 6 PSI, you'll run lean...

Default Yes they will hold. Have seen it done on many cars....

My fathers 82 coupe runs 10-11 psi of post and is running the stock injectors. Also I have seen other turbo coupe projects that have the stock injectors. There is very little differece (if any) in the turbo injectors and the stock coupes. Now, the fuel pump you may want to upgrade! The direct fit one is the Urq but a NG fuel pump will also work. This will increase the fuel pressure to the injectors, which will allow the fuel to over come the boost in the cylinder.
