2sq alternating and i think you can do it.
problem will be that it'll idle around 12:1 if you want it stable... and there are points on the ve table where you want less than idle fuel... this is going to be more of a hassle if you want perfect afrs.
If you're ok with sacrificing this, then go for it. I assume you're going for some big numbers on this motor?

fwiw: i ran 550cc injectors on my old turbo 1.6 ok.

Tyrone,

Why are you going with such a big injector? What are your plans for that Scirocco man!

I run 500cc/min ok, there`s a version of extra with hi-res code floating about and it makes a difference. 65lb`ers are on the large side for a 1.8!

FWIW I run 850cc injectors on 2.0 liter 4 cylinder and it behaves just like stated below. Idles around 12:1 or a touch richer, but idles good. I smoothed the VE table around idle and I don't seem to have a problem with it so far, but definitely tougher to work with than smaller injectors would be.

im running 730cc injectors on a 2.4 with no problem, idle kinda jumps around but im fine with it.
