Next Gen is here: Full-Race/Borg-Warner EFR7163 in stock location. 440whp/443wtq
Car: 2008 Subaru Impreza WRX STi
Tuner: Me, Paul Leung of YimiSport Tuning Dyno Info: Dynojet 424X Ambient Temp: 95*F Elevation: about 1300' ASL Transmission: Stock 6MT Gear: 4th Peak HP at RPM: 440whp @ 5900rpm (E85). 350whp @ 5900rpm (CA 91 octane) Peak Torque at RPM: 443ft/lbs @ 3600rpm (E85). 353ft/lbs @3600rpm (CA 91 octane) Baseline hp/tq for a stock on same dyno: 230HP/255tq - 2008 STi Target Boost: 25 PSI (E85), 22 PSI (91 Octane) Target AFR: 12:1 (gasoline scale on E85), 10.9:1 on 91 octane Fuel: E85 and CA 91 octane pump gas Mods: - Full-Race uppipe and catted downpipe to locate a Borg Warner EFR7163 (2013 release turbo, one of only a handful that have made their way out in to the world) in stock location. Ready to bolt up to all OEM or aftermarket parts that will fit the stock turbo (inlets, TMIC's, FMIC's etc...) - Fujitsubo Legalis R catback (with the 2.5" taper intact) - Custom YimiSport 73mm CAI - Custom YimiSport FPR kit - APS turbo inlet pipe - Grimmspeed hybrid EBCS/MBC boost control - Deatschwerks 1000cc injectors - Synergy 300lph fuel pump - Cobb AP The narrative that no one cares about: Stock motor (60k miles), stock TMIC and stock exhaust manifold. Basically just enough mods to supply enough fuel, sample the incoming air and get it out the back of the car as quietly and cleanly as possible Every so often a turbo company introduces a product that "spools like small turbo X, but make power like BIG turbo Y". Physics being the b!tch that it is, has usually proven such claims to be more hype than reality So when Geoff from Full-Race told me about a new turbo that would spool like a turbo 10lbs/min smaller than it's rated flow, my interest was piqued, but my BS meter was similarly pegged. I'll let you guys be the judge, but I think even on my less than fully supported test platform, Borg Warner and Full-Race have come pretty close to their claim. I have always wanted to have a Subaru that made 500wtq before 4000rpm and still made over 450whp. I'm not quite there yet, but with a couple more bolt-on mods I can easily see it happening even on the stock block. In the mean time, I've been enjoying one hell of a broad powerband and nearly instantaneous boost recover all in a damn near stock appearing package Pics: Dyno Graphs: Pump and E85 Pump and E85 compared with a typical Stage 2 08+ STI Damn near stock turbo spool with nearly 200whp more by redline... not too shaby

I believe without a bpv it can hold boost better with high boost numbers, because the boost will start to open it. And i heard its easier to tune without it

Awesome! I believe perrin (?) tested the EFR7064 to be later spooling then stock and the even smaller one (6458?) spooled faster, but now this 7163 spools as fast as stock AND gives wayyyy more flow/hp!
What made this happen all of a sudden as a 7163 looks like its the same-ish dimension as a 7064 and parts are as light-weight as possible already with the EFR line? More aggressive trim? 320 hp at 4000 rpm! Wow! |

^^^ I believe it IS essentially a 7064 but keep in mind that the 7064 does not come with the small turbine housing which is .64 A/R I believe.
It seems they have transplanted the 7064 CHRA into the 6758-type Turbine housing. Jasper. |

Some articles I'm seeing on it are talking about what's actually a new turbine wheel shape to extract more energy from the exhaust gas at lower flow levels. I just think the whole thing's pretty sexy.

That's a lot of torque for 3600 rpm.
And 300whp. Wow. I want it. |

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. Quote:
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. |

Great to see. Maybe I should have waited I wanted to do a stock location 6758 twin scroll. Do you know if there are any plans by BW to and TS to the smaller range and full race to offer a "stock location" ts option?

71mm compressor OD and 63 mm turbine OD. The EFR6758 has a 67mm compressor. |

This is pretty nice so I'm guessing this would do about 370-390 on 93 this is pretty awesome it pretty much makes it worthless to consider a GTX30 period. Easy installation and internal WG and stock spool this is very niiice

As for the comparisons to the GT series turbos, the biggest difference is in the turbine wheels. The Garrett GTX compressor wheels are very nice but are still paired with some relatively old tech turbines. They work nicely as well but the newest EFR stuff really does seem at the very least a significant evolution of turbo technology. |

- Does this frame match any existing (I use that term loosely) EFR turbos? Could we use the UP / DOWN setup with a 6758, for example, then move to a 7163 in a few years when it's available? I really like the idea of an EFR setup that uses the TMIC. |

Now if they could make one that will mate up to the factory twinscroll header, new uppipe portion and downpipe obviously, twinscroll EFR anyone?
My 8k rpm would be happy! I'm willing to be a guinea pig |
