I suspect so ID1000 would work fine. We use them alot in many jap vehicles which have the same injector size as 1uz. One of the nicest injectors I have worked with, especially when they are "technically" too big for the application. They done run the bosch plug though.
ID did have a 1600cc but they have been discontinued.
Dont you have a first born child to sell? or a Mrs to work on the street corner? Failing that maybe porn off a Kidney ( you have two anyway ) and if none of those work then maybe sell off your left testicle. You know the ID's will be worth it.
We have also used some bosch injectors by machining the fuel rail to suit the larger bosch o-ring. We use 1600cc in RX7's so maybe that would solve you issue.
