I have been finding this site quite helpful on finding any sized injector from other vehicles. it also lists part numbers and also tells if it is high or low impedance it also shows the advertised flow rate. the best part is the way this site categorizes the injectors by plug and injector type. so if your looking for a toyota style denso plug there is a link that takes you directly to those injectors. check it out. it may help you out or even you turbo guys.
