Acura RDX 410cc Injectors
They fit with a teeny bit of work. Maybe too small for most turbo guys, but a incredibly high quality injector for cheap. They will flow closer to 600cc at 60 psi.
~$160 shipped brand new from Acura.
$30 for adapters, $30 for pigtails.
Going on my 12:1 compression BP-4W running E85. Just had to add about 1/2" of additional spacers under the rail. Used trans bolt washers.

Adapter hats:
RDX injector hats for B/D series motors
These are pretty common, lot of other vendors sell em. Best price I've found though.
Denso Acura RDX Injectors
Select "Clips Only" there.
Of course, you can order the whole shooting match from them, injectors and all, but you'll save ~$25 getting the squirters themselves from a dealership online.
I removed the lower o-rings, the tapered part seals into the lower injector seal very well without it. Tight fit though.

They are still pretty damn good injectors. The Acura white papers credit the switch to these injectors with some substantial improvements in fuel economy, emissions, and power. /shrug
Found out today that spacing the rail out to fit these means the upper plenum on 99/00 manifolds can't be installed or remove with the rail in place. I'm guessing a thermal intake manifold gasket will remedy this by pushing the manifold another 1/4" away from the head.

Going to be running these as well, thanks for sharing. It looks like you still have the little plastic "L" protrusions on the injector bodies right under the adapters. Is that correct? I cut those off on mine to get the length closer to the stock injector, but I'm curious if I will need to space them as you did.
