The ERF 7163 has been in the development phase for a long time now and it's finally in production and should be available very soon .

The 7163 is the largest capacity of the smaller or B1 frame size EFR turbos and it was initially supposed to extend the performance of their 6758 by about 50 Hp . When it was announced people wondered why bother with a 71mm compressor and a 63mm turbine when BW already had a larger frame EFR 7064 turbocharger . The answer is that the B1 turbos are more compact and have a smaller inlet boss size - basically easier packaging .

Compared to other EFRs the 7163 has a unique mixed flow turbine wheel which is leaning more towards being an axial rather than radial inlet style turbine . The final version is also getting an aluminium centre section which makes the unit about two pounds lighter , light is good and rusty iron never looked pretty .

Compressor housing is the same as the existing B1 turbos .

Exhaust housings will be different because BW went to a lot of trouble to make the 7163s hot side light responsive and wide ranging for it's size . Also stainless is much easier to weld than high Nickel content iron .

From what I read there will be a twin entry T4 flanged IW turbine housing in 0.80 AR . I think there will also be a couple of open or single scroll turbine housings in V band style and a flanged one as well .

Full Race Geoff has only good things to say about the 7163 and recently mentioned that the way to max hot side flow could be with the single scroll housing which some think will be a 0.85ish IW T3 flanged one .

Power potential is said to be in the 5-600 Hp range with response not like anything we've seen before .

Turbo junkies the world over are holding out for this 7163 because the power range it's aimed at is where most propeller heads realistically want to be with a souped up roadie . With engines in the 1800 to maybe 3000cc range and beyond it should be the ducks guts . FR has been developing kits to put them on Ford 3.5L direct injection Eco Boost petrol engines and the results speak for themselves .

For RB20s and 25s you would expect the 7163 to solve the response/power issues you at times get when using Garrett or similar turbos eg 3071R 3076R and the GTX versions . Fingers crossed we'll get GTRS response and maybe GT3576R potential .

Looking forward to real world results , cheers Adrian .

Have been waiting for these to emerge for a couple of years and agreed, a lot of the stuff Geoff has said and what has been posted do make them seem like they COULD fit into my little list of "magic turbos" that have an amazing balance of response vs power compared to other things in a similar range (shared with the likes of the FP3582HTA, Precision PT6466 CEA, etc).

I too am counting on GT-RS-esque response, but until I have evidence to suggest otherwise my power expectation for it is maybe slightly higher than that of a cast wheel 56-trim GT3076R - which would be a great success if it achieves that. If they pump numbers out comparable (in peak power) to what a GTX3576R is capable of then I'll eat my hat. Even an EFR7670 can't do that (though I'd have an EFR7670 over a GTX3576R in a heart beat), and unless Borg Warner are intending of getting rid of their EFR7064 and EFR7670 and giving housing options that those other units had as well then there is nothing to suggest that it's going to be THAT good... which is hardly bagging it, so much as saying "Come back down to earth, Adrian" ;)

      This would be a new pump with new gears. I'm just unclear on whether it's a good idea to run more oil pump flow if you don't actually need said flow. Oil level is set a minute or so after shutting off a warm engine so wouldn't the high RPM oil level in the sump end up lower all things equal? Plan is OEM clearances, main concern in my mind is whether the OEM pump can keep up with the flow requirements of any additional oil coolers.

      Don't do what I did, use a 300000km old housing with billet gears. The old pump probably was clearanced with saw dust, Edward Lee's special engine treatment sauce and a good odo wind back. I had oil pressure issues, then replaces pump with new housing, new billet gears and 2x track day later binned a motor due to other oil related issues due to a previous engine builder. Long story short, buy a M2 or 3 or 4 N55/S55/S58 and enjoy life.

      Yeah. "New pump" does not have to mean "massive pump".

      Well, can you still get an OEM pump, and by the time you're buying a Nismo/N1 etc, just buy another aftermarket pump. It's better to have the pump able to flow more if its needed, than for your pressure to drop off. At any point in time, you're replacing the oil pump in a rebuild. Aftermarket pumps are likely going to be a better economical choice, and they don't have any negatives, even if they can flow more.   Also, when you're saying "replace the pump gears" are you meaning leave a 25+ year old housing in the engine with unknown wear, and just put new gears in? As that sounds silly to me, especially if you do have that minute amount of wear, that means your new pump gears now have a little bit more clearance beside them, which means, whelp, you may not get to build a lot of oil pressure or make a lot of flow.

      Right, but if you replace the pump gears + put a spline or sine drive gear on the crank on a Nismo/OEM/N1/etc pump at that point do you really still want more flow/oil pressure? Let's say this is a the aforementioned "keep it simple" build, no more than ~400 kW at the crank.
