V-band Housings for EFR Turbos

That makes sense, simpler is better. And while v-band inlet is simpler than T25 flange, the IWG is simpler than an EWG (and the Borg ones are as good as an EWG).
I wonder if the v-band EWG housing is the same one Indy uses? Or that housing pictured might be an Indy one and they will also offer a v-band inlet IWG (doubtful but I can dream can't I?).

I am really hoping that the inlet for the turbine from the manifold is the same size of what Tial uses on their V-Band housing. If I could swap back and forth between the EFR and my GT2871 I would be very happy. I also would like the EFR to have the internal wastegate along with the V-Bands.

The IWG on the EFRs makes the turbine-to-downpipe part of the housing really long, which makes fitment an issue. But from the looks of the v-band housing, you might be able to just swap it straight in where your 2871 was. Except I don't remember if you are EWG or not...

Right but if you don't mind keeping your EWG, I'm thinking that with that EFR v-band housing you could just do a straight swap with your GT2871 from the looks of it. I'm not sure what the coldside looks like compared to the Garrett, you might have to modify the IC piping.
Just swap it out with no mods at all. Back to back testing by removing a couple of v-bands.

after some more research.
they are doing both. wallop. the housing looks to be in similar proportion to the t25 flange, so wont be interchangable with a tial/garrett unit without the DP going too.

yup! I cant tell you how happy this makes me. Lets just hope they are investment cast like the photos. I've heard too many bad stories of EFRs turning up with sand cast housings that look like a piece of ****.

The sand cast housings are a temporary solution because the early investment housings were failing QC. The final housings for all of the turbos will be investment cast.

Also the making of a downpipe that does not need the EWG dump tube would be easier for me.
I think that my GT2871 will have a slightly better top end the smaller EFR, but I think that the EFR will have a better mid range. Now if I go with the slightly bigger one that Soviet is now rocking I think the top ends would be very similar, with the EFR having a better mid range. If I win the lotto or find me a sugar momma I would love to also throw a GTX of similar size on to test that also.
