So basically i bought a Sa22c rx7 with a series 4 bridgeported turbo engine, and it needs to be cranked for about a minute to start on morning, but once i spray some sort of starter fluid into the intake manifold via a port mean for a vaccum hose and it starts instantly....... changed the plugs,re-did the entire fuel system except for the injectors, and it still continues, the injectors where serviced but still looked pretty suspect....any help would be pretty appreicated

 

A bridge port by design needs to build compression to start.

I didn't think a bridge port was a good idea for a turbo.
