Supra/Cressida Injector CCs???

I'm new to toyotas and was hoping that someone could help me out here, and already used search function. What are the cc's on injectors from these cars:

1st Gen Supra Non-Turbo
1st Gen Supra Turbo
Toyota Cressida (early 90's) 6cyl

First gen turbo? I don't think the turbo was introduced untill the MK III in 1987. I'm fairly sure the 1979 and 1980 Supras didn't have turbos.

i was going to start a new post but if someone could answer his questions that would help!
I just picked up some 91 turbo injectors and wanted to know if they were 440's 450's or 550's? I am getting a whole lot of wrong info and wanted to come to the SOURCE!

All MKIII turbo injectors are 440cc low impedance.

well i found my dsm's so i am selling these
