i see no bov bpv ?

any pictures of the up pipe and downpipe ?

any problems with boost like others had controlling boost?
Can't get one quite yet till Borg Warner officially releases the turbo, but I do know that Full-Race is all set on their end with the uppipe/downpipe and ancillary bits. As for the BOV/BPV, all EFR turbos have one integrated in to the compressor cover, hence the block off plate on my stock TMIC

No boost control issues at all. I have the high pressure actuator and that combined with the hybrid Grimmspeed boost control allowed me to dial in the exact amount of boost I was looking for with rock steady boost control.

It seems they have transplanted the 7064 CHRA into the 6758-type Turbine housing.

Not exactly. The EFR7163 is indeed a B1 frame turbo (like the 6758) which is what allows it to be located in stock location. However the compressor and turbine wheels are all new. I believe the turbine wheel in particular uses mixed flow geometry. The exact physics are a bit beyond my full understanding so perhaps the folks at Full-Race will chime in on that. Suffice to say that the response of the turbo shows the value of the new wheels.

Also just for clarity sake, the EFR7163 I have on my car sits in basically stock location but it is NOT a bolt-on turbo (ie: bolts to OEM fitment uppipes and downpipes). The turbo has a T25 inlet flange and a 3" v-band discharge. The Full-Race uppipe and downpipe are what allows it to fit in stock location.

Here are a couple more pics of the turbo, uppipe and downpipe:

The last 2 pics of the DP show a few extra welds as I made some adjustments to the original prototype for better fitment and sent them back to Full-Race so they could adjust their fixtures. I have the revised DP and UP on my car now and they fit great.
