Here's the reply I got from AquaC when I inquired about upgrading the pump:
Franklin,
Thanks for the message, I can help out. I would not recommend using the Mag Drive 5 on the standard Remora. This is an upgraded pump to use on the Remora Pro and would be too powerful for the standard Remora. I would recommend going with the Mag Drive 3 and many customers upgrade to this pump when using the Remora with good results. You will need an adapter as the pump outlet is 3/4" and the Remora inlet is 1/2".
Please let me know if you have any other comments or questions and I can help out!

I got the Mag5 anyway since I'm all about going overboard =)
Kinda regretted it at first as the it did overwhelm the Remora. I installed a ball valve to staunch the head pressure a bit and the Hagen surface skimmer also slowed things down. Took a while to tweak it, but it kicks butt now. I have to empty the cup about 2x a week with nasty dark skimmate whereas before with the Maxijet I'd be lucky to get a cup every 10 days or so and the skimmate then was just tea coloured.
If I could do it over, I'd stick with the Mag3 for the regular Remora and the Mag5 for the Remora Pro as recommended.
