I want to put the new style injectors in my 91z does anyone know what I need to do to complete this tack

 

Well deductive thought suggests if you need new style injectors you may need an FSM for information regarding that. In the meantime:

Lower Intake Machined for New style rails

6 x Fuel Rail to Lower Intake O-rings

New Style Fuel Rails

6 x New Style Injectors

6 x Upper and Lower Injector O-rings

6 x New Style Injector Clips


Harness connectors may shorten that route considerably.

 

What you need to do is not waste ur time

unless over half of your injectors are bad or your car was in some accident where the fuel rails were damaged, i 2nd Mousier. Don't waste your time or money.

 

While I somewhat agree, I also somewhat don't. The bottom line is, early style injectors are more prone to failure because of their design (I don't feel like elaborating, just seach for posts by Greg Dupree on 604Z.com if you want the facts, it has to do with the constant voltage applied to the earlier style ozidizing the additives inside the injectors causing them to rust from the inside), as compared to the newer style which are not.

If he's only replacing to go to the same size but newer style while his current injectors are fine... yeah, that's pointless.

If he's got dead injectors, it completely makes sense.

If he wants to go to larger injectors without worrying about failure and is going to replace all six anyway, it also makes complete sense to go to the newer style injectors.
