You generally don't replace injectors, you have somebody rebuild
them. Max and I have both used Mark Blevins in SC. His work is good
and reasonably inexpensive. The actual doing of removal and
replacement is super easy. The hardest part is having a big enough
socket. I think I still have Fred's... Figure maybe 15mins to remove
and half an hour to install with new injector return lines. Mark's
turn around is quick, I shipped mine out just before a week long
trip and they were back before I was.
I can't remember what nozzles I used but I got them from ID parts
and they were a brand Mark approved of. They are slightly larger
than stock and might give a slight improvement in power. They'd be
appropriate for your car too...

If you have leaking outside the injectors, all you need is one meter
of return line hose. It just presses over nipples on the nozzle
holders. A needle nose pliers is a good tool to remove the ends from
the nozzle holder.
You can buy that at a stealer or you can go to an industrial supply
house and buy 1/8 i.d. viton hose, which will last longer.
If the engine is running poorly, then pull the nozzle holders and
have the nozzles tested.
To take out the nozzle holder, you need a 27mm or an 1 1/6" deep
socket with the splines broached deep also. Sears crapsman used to
be good sockets.
Each time you remove the nozzle holder, you need to replace the
nozzle seal in the prechamber in the head. It is a tapered steel
seal. You need a machinist's scribe or somthing similar to get the
seals out. In a pinch, I have used a long handled allen wrench.
Seals can be picked up at a Bosch injection shop, the stealer or
ordered online.
Removing the nozzles, and replacing them needs to be done in cleaner
than surgical conditions. Compressed air is a necessity. any speck
of dust that gets into the nozzle can ruin the nozzle.
