I will have to look up the numbers, but my EFR 7163 kit is somewhat lighter than stock turbo setup..

The only non stock frame setup I'd go with would be an EFR and since they don't make reverse rotation EFRs they're a ***** to package nicely and the kits that can do it you're spending $6k at least all said and done.
FWIW the new FP/Xona wheels outperform almost all the other stuff out there. I think once they start posting results with their UHF reds we'll see some nice curves. Couple it with the significantly better water jacket design that FP uses and you end up with a setup that runs at a cooler and more consistent temp.
IMO a twinscroll housing with an A/R around .9-.95 (12-12.5cm) would be the sweet spot for having great response and a strong top end without running crazy hot with extended use.
As for lining up vbands, if a housing like that were to come to fruition, it would be compatible with all the OTS stuff like STM's recirc downpipe etc.
The stock flange gets a lot of unwarranted ****, but the reality is if you're shooting for any amount of power less than 700whp the flange itself isn't a restriction.

Not a lot of results to go around, but there's a plot and some discussion in this thread: https://www.evolutionm.net/forums/ev...green-uhf.html
The dyno posted on FP's own site doesn't even look that great: http://www.forcedperformance.net/mm5...t_Code=2007020

Results are still few and far between on the green. The red isn't officially released yet.
The plot that FP has posted is for a rally car. It's owned by Dave Kern and he's nothing but happy with the setup from what he's told me. Rally cars approach making power differently than other cars. Since he's racing on loose surfaces a lot he doesn't want to bring power in as soon as possible and having the most power that's the most manageable is what wins stages.
The wheels are of the same design in their newer Xona stuff which has been setting some very impressive numbers for their given wheel sizes.
I've had a UHF green sitting in my room for the past 8 months and it'll be getting put on my car this winter. Goals will be fastest possible spool and 500whp on a 2.4LR non mivec engine. If exhaust temps and back pressure stay in check then we'll be pushing it further.

I actually sold that haha. Then bought a freshly machined 2.0L 63 as a spare and now I'm about to pick up another 64 block and crank because I want to see how it will respond with the increased displacement before I decide if I want to stick with a 2.0L or go bigger when the time comes to build a respectable engine.
