found some injectors in the jy-which ones to use

I was at the pull-a-part today looking for some injectors for my NA2T build. First I came across the famous 1970's Mercedes 450 and got all 8 injectors from it. Are these 420cc or 440cc? I can't remember. I know injectors rarely go "bad" but these are in pretty bad shape. Almost all the pintle caps are gone, think i can fix that but some of the connectors are FUBAR, not too sure if I'm going to be able to use these. I did however find a 1986 toyota supra. Pretty sure it was a non-turbo. I'm trying to figure out what size these supra injectors are. The plastic wire connector part is a kind of a greyish white color and the pintle caps are green. The injector body is black and I'm pretty sure they are low-imp as they measured out at about 2.4ohm. I tried to do some research but cannot determine what size injectors these are for sure. Can anyone give any info/insite? Whichever set I use (if either) I plan on having them cleaned and flow tested and all that. The Supra injectors are in much better shape than the Mercedes and I hope to use them if it is at all worth it. I also managed to get the injector connectors in case I need them. So, what size are these Supra injectors and should I even use them for my NA2T build? BTW, I have a set of stock dual/side feed, low-imp turbo injectors that I can use but would prefer to start with a little more headroom if possible. Thanks for any info anyone can provide.
