i have a 90 300zx i picked up pretty cheap ive got it to run and i have 2 dead injectors. Plenum is pulled i went to a yard and pulled some injectors and rails from a 97 or 98 J30, its the newer style injectors. I want to convert it to new style; I cut all the pigtails because i knew i would need those but apparently the intake is different and someone said something about using some spacers. What i need to know is if there's a way to not have to use spacers and what i would need to do or where can i get spacers.

I've searched for them online and cannot find them or what do these spacers look like anyone have a pic and dimensions on them i could probably make them and where do they go? I'm wanting to get this car going asap so an information would be so much appreciated because i have no idea thanks to anyone willing to help me out.

It's Friday, and I'm in a good mood, so I edited your post to make it easier to read. Please use somewhat coherent punctuation in the near future. :bigthumb:

Regarding your question, you need to get new to old style rail adapters. They can be purchased from Z1 Motorsports: http://www.z1motorsports.com/product_in ... ts_id=3348
