Seem like a good candidate for Kjet heads. Anyone ever try?

I picked up a p/n 280157012 just to eyeball it. They're a fairly easy to find VW/Audi part. 4 hole injector, end cap looks to be the cone-type (not the two spray version) but I haven't ran any fluid through it to double check yet. 26.9lb/hr equivalent - plenty of overhead for power without being expensive.

Tip is just about at the opening to the intake port, not quite as long as a kjet injector but way closer to the intake path than most others.
