I'm in the process of buying parts for a small turbo build and I'm wanting to know what spacer/ adapters I need for the fuel injectors im buying. I have a 2007 nnbs 5.3 (stock) with cai, and lts. trans has cervos. I'm new here and im still learning about ls motors. I do believe I attached a pic of the injectors I'm getting. thanks for the help.

 

get top mount height adapters. not the FAST lower mount adapters. they are junk.
racetronics has the adapters i am talking about. they are 1/2" difference. reuse your oem clips and the top o ring from your factory injector.
