To drill them you need to use a drill press on a slow speed and have the rail clamped and then push down nice and light to let the drill do the work, 

And as they say, you can never have too much lube.

Went for ID1300x2.

Not sure the delphi 1400's were bad per se... just that their pintle position really doesn't suit RB rails

My 1300s are the same. 

You went way too small if you'r aiming for 500kw Pete.

Piggy is at 87 or so % duty cycle with 1700s at 486kw.

This is FICs calculator .

https://fuelinjectorclinic.com/flow-calculator

For shits 'n giggles I entered 670 wheel Hp at 43.5 base pressure @ 85% DC and for 4 and 6 cylinders (injectors) . It came up with around 1860cc and 1250cc for 4 and 6 .

I think I prefer ASNUs ideas about making up their own diffuser plate cap fitting than the exposed ball valve . They have a version of the 1650 or whatever EV14 and you'd think it would break up the spray a bit better than a bare ball .

High chance that's stock pressure Paul, if they were at 3.5 or even 4 bar you would be at like 50~60% DC haha

Downside to higher pressure, the car won't idle too nicely on 98RON as the IPW is so low - but then again as Paul would say it's commuter fuel.

True. But then you could just size injectors correctly and not flog the ass out of the pumps.

Also depends on how much boost you want to play with - all a balancing act at the end of the day.

ID1700X if you baller 1550cc Bosch Motorsports if you're willing and 1250cc modified Bosch injectors if you're a bit strapped for cash lol
