They are 370cc injectors quite a bit smaller than what a normal 13b running 550cc injectors.

Also SR injectors are side feed...

So no they won't work, and would be a downgrade even if they did.

as long as the length of the injector, harness/injector plugs, and the impedance are correct...then yes.

No, the injector needs to be sized correctly to fit the stock engine and fuel rail hole diameters, as well as allowing for the height of the stock fuel rail standoff distance. Also, the impedance needs to be within parameters. The electrical plug needs to be the correct type, but usually you can get around that with aftermarket pigtails.
