Why not just go all the way to 1000s for "max headroom"?

(It's actually a serious question though. No downside, right?)

BR says it all the time. Put 1000's in so you won't have to change them again.

I have 680's that will be going in with a BBK turbo in less than 2 weeks on my evo 8. We will see if the 680's are doing at 26-27psi boost

I always thought 1000cc injectors were best suited to guys who run meth, race fuel or very big turbos.

I can totally understand the headroom logic, but if a car like the HKS CT230 uses 760cc injectors with a stroked engine and a 3076 then I don't see why a car running pump gas and a stock frame turbo would need to go bigger than that.

Ideally I want to use the smallest injectors I need, perhaps with a fuel pressure regulator (already have the defi fuel pressure gauge) - want to avoid unecessary stuff like a fuel rail etc. if I don't need it.

To each their own though

we run 780's in almost everything... they are the simplest to dial in, always work well... and are available...

i ran 850's when i made 499whp on pump on my dyno (injectors that are now in charlies car)....

There are a lot of broad generalizations, assumptions and dubious comparisons made in your post. For example, guys injecting any significant percentages of methanol can actually get away with running a much smaller, as opposed to a larger, injector than the same engine running on a pump gas tune.

I can certainly understand a tuner preferring to stick with what they are familiar with. FWIW, in winter weather I was in the 90% duty cycle range with a white rabbit VIII turbo (for the newbies, the WR was a billet wheel FP turbo sold in 2005) on pump gas with 660s.
