My Googling doesn't really show any information about those injectors other than a page at O'Reilly's web store. However they show those injectors as a replacement for both the NA and TII S4 RX-7, which is WRONG! NAs use 460CC injectors, TIIs use 550CC injectors, so there is no way this injector fits both cars. You're going to need to verify that you have 460CC injectors before installation...and that's scary if they are because it means people are buying these for their TIIs and ending up with too small injector.

From the picture they look like the typical Denso style so if that picture is correct, they will fit.

I can't find any info about that o-ring kit you mention. It would help if you post pictures of both the injectors and o-rings.

However, assuming they are the correct injector, you'll need one of the following per each injector to install them:

I hate to say this, but it's almost never necessary to buy new injectors. Most communities have a local injection shop that can clean and test injectors, returning them to factory specs. Generally this costs about $25-$30 per injector. And there are companies like WitchHunter online that can do this via mail order. $800 also seems, well, pretty expensive...
