Had good like with the deatschwerks phase 2 kit. Almost have 100k miles on my injectors and it runs flawlessly. $689 for the injectors. Like 300$ for the phase 2 adaptors unless you get the 94-96 rails then you can avoid the adaptor kit.

so if i get the 94-96 fuel rails would i still be using the 370cc injerctors or would it be the lower cc injectors? and if i gopt the phase 2 adaptors would it let me put the 94-96 injectors in? sry im new to replacing these injectors im trying to decide the best route to go cuz i might as well since im spending all this time under the plemun. i might be stuck with just replacinmg the ones that ohm test bad whitch is like 3 or 4 of them

after this gets done i get to rip the front of the engine off and redo the timing chain guides but one thing at a time

If you decide to upgrade to Phase II injectors, try to pull some injector rails and a wiring harness from a car in a salvage yard. Make sure someone hasn't tried to try off the passenger side rail before you get the rail. There is a fuel hose at the back of the rail that can be stubborn to remove if you are not familiar the location where the rail and the pressure regulator join. I use a knife to slice through the fuel hose at the point where the rail and regulator metal fittings join. If someone tries to force off the rail, it will be bent and most likely will not seat properly. If you do not want to go the Phase II rail and injector harness route, the Deatschwerks kit contains adapters and wiring plugs.

Once you start rebuilding I'll post some pictures of how to test the injectors and fuel lines for leaks before you reinstall the plenum.
