Here is a question for the pro’s. Will DSM 450cc injectors fit into a S14 KA?  
Meaning fuel rail/harness compatible?

Thank you!

To use the cheaper injectors instead of forking out hundreds everytime you want to replace your injectors…[/quote]  
right on the money.  
and msd injectors fit perfict in it. There are tones of diffent sizes of them.
