I have finally found the real 2ZZGE injector capacity, I have found this in 2ZZGE Toyota tecnical manual.

at 3 bar of fuel pressure the injector have about 350cc of capacity(between 330cc and 370cc)

these are similar of Scion TC injector that have about 340cc of capacity (between 320cc and 360cc)

 

good info.. installing a 1ZZ TB as we speak.. getting the WR manifold re-flanged for it, then a tune.. was wondering about bigger injectors.. again, good info.

 

Thanks.

The 1ZZFE injectors at 3 bar of fuel pressure have about 265cc of capacity(between 240cc and 290cc)
