    STI pink injectors wiring harness compatible?

    I found using search that many have used STI injectors (525cc) on their SHO engines with 0.5" spacers for the fuel rail but a bunch of the pictures are no longer hosted. Does the Yamaha injector harness directly connect to these injectors or is an adapter needed like on injector dynamics units?

    Also to install I would just leave the factory rubber inserts in the intake manifold correct? Old threads point at multiple ways to do this.

    For reference I'm looking at these injectors:

    Any better sources?

    Those are the same injectors I use with my set up and they work really well.

    Good deal... I'm looking at running the same with the ET15.5. Mind sharing your base fuel pressure settings for a starting point? I'm still weighing RRFPR versus dynojet CMD. Thanks.

    I was going to ask that seemed really high with those injectors. Cool deal. I think I'll add the riva rrfpr and ET15.5 wheel.

    Pics no longer show up is why I started this thread. They are rated at 525cc but are actually 555cc depending upon who you ask. Jim uses them on a lot of SHO's.
