I know this has been discussed before, but can it be done? What would be holding us back on the S1? I know some type of injector spacers can be used in between the fuel rail and injectors, along with a few other things. Feel free to discuss if this is possible. I would like to see a possible product in the future, since my dad is a CNC machinist and can possibly work on this with me on the side.

Been there. It'* possible, but the cost of doing it is far greater than the S2, making it impractical for the typical S1 owner. So I stopped.

There'* no point in doing something just for myself that nobody else would be able to do because of the cost.

Moving to Forced Induction.

Darn, since my dad has a nice chunk of aluminum he got from work for free, i was hoping to fabricate something out of it. I figured it would be costly, but no idea of being that much more than the S2'* IC.
