Good hint Cedric. It seems the 0280158123 would fit nice for my application.
The only thing that bothers me is these injectors are for E85 only according to this document?

A quick google says its the Porsche turbo/gt2/gt2rs injectors, they work well with petrol aswell. But have stainless parts inside for handling ethanol and methanol.

Yeah, I just used long tip injectors in the stock location with adapters, much easier.
I used the Bosch 0 280 158 123 injector, from the 997 Turbo, it's 627cc.
0 280 155 892 is another smaller option if you prefer, 365cc from the Audi TT - probably a better choice for an NA EFI conversion.
Trimmed down a set of VW 058 133 555 injector inserts, taking the top flange off so they'd fit.
Been running this config for a few years now...

When I make an extra +2.7HP then you won't have to make the journey 
I also suspect that the result of my journey might follow the law of diminishing return. Like a $1500 set of speakers vs $5000-50K
It is likely that Cedric's plan of attack is the best bang for the buck. Just a quick clean up port job (also pointed out by Gegge a long time ago)
The only thing I can see right now that would be the game changer is a proper intake that uses the full flow gain of the head
