Difference between Nozzles and Injectors

[Heavyd1980]

Alright so I have a question is there a physical difference between full body injectors and just nozzles? I have never seen either out of the engine other than pictures. Any pics would be great and how would a person go about finding out which brand and hp they are if they are already installed. any help is appreciated!

Really simple... The second part from the left is just the nozzle and pintle.

At any rate when you change nozzles and pintles you'll need to take the injectors in and have them pop tested. If the pop to early then tha pull the shim (the small washer to the right of the spring) and change it for thicker. Then retest again.

ok thank you Mopar. so is there a way I could tell physically whether or not mine are injectors or nozzles? and what brand they are?

If you take them apart they will have marking on the nozzle. As for the Injector body should have marking too that you should be able to Google and find some information... If not then consult one of the fine vendors here I'm sure some would know!
