I don't think I'm up for the dremel method since it's not my car (don't want to screw the pooch on someone else's ride). Now I know the difference between Z31 & Z32 and the proper injector size (270cc), that's a good step forward. Does the plan of extraction & professional cleaning sound like a good approach to you? If I have to replace them, does the blue-dot / black-dot stuff I see all over the parts merchants indicate the injector size or something else? Is there a recommendation for manufacturer (OEM vs aftermarket)? Should he avoid refurbished injectors?
Thanks for the help...

The dermal technique is a by far the easiest and quicker way to do the injector swap. I have done it to most of my injectors just make sure you don't take too much off the runners or you'll make a hole in the plenum. If you do remove the plenum to get too the injectors you'll have to replace a lot of little hoses that add up $(old and brittle) and takes a whole day to start and finish.
As for injectors always get OEM because they have been proven to be reliable while others have died in a short time of being installed. They also had a injector change in 94+ Z so make sure you give the correct year when ordering. I suggest ordering new for reliability but if you want used low mileage injectors are fine so long as you have them professionally cleaned like RC.
As for the dots I'll have to look it up? What year Z are you working on?
