Thank you. After having this car for 12 years and watching it evolve from a daily (1 year) to a more dedicated autox car (6 years), to a test mule, etc....we decided to put together a few items that we've talked about for a long time. We're happy with the way the car performs on the dyno as well as on the street and testing out a 2.0 liter was refreshing, because we do so many 2.5 liter cars at our facility. We look forward to finishing a few items and getting it out on track asap!

Ravel36 - What gear was that dyno pull in, and which WG actuator are you using?
NICO Turbine - I was telling a friend about this car the other day, absolutely love it!! |

Low end seems really weak on that dyno for a 7163. Going to just blame it on the dyno operator though setting the pull duration too short and starting at 3k rather than 2k.

Possibly, I wouldn't know. But drivability is great, boost comes on strong once the turbo starts to spool. I have only hit 19psi once in a third gear pass, I had to grip the steering wheel pretty hard because you can fill the chassis twist when the boost comes on crazy, but awesome. Puts that ear to ear grin on your face. |

Maybe i missed them, but is there any EFR6258 dyno numbers on a 2.0L in here?
fwiw my motor is the usdm 2003 WRX variant. I'd like to get a sense of the general characteristics related to spool for this turbo, on this motor. When is peak poost? how steep is the curve, etc etc. I suppose a dyno plot would be ideal. Thanks! |

evans-tuning.com in PA did 2 identical cars (WRX 2.0L) with stock motors and identical setups except 6258 vs 6758 was the only difference. same engine setups, same dyno, same timeframe. this is the first stock location EFR kit this tuner has done, he said "that 6758 turbo is awesome. Seriously. I am impressed" EFR6258 on stock EJ20 longblock, 93octane pump gas @22psi from Evans-Tuning: EFR6758 stock EJ20 longblock, 93octane pump gas @22psi: both of these setups have the soft "mid boost" wg actuator, since they are 93 octane pump gas builds only. I recommended to install the stiffer wg spring and check back edit: subiefest is this weekend, we are doing a big sale on these subaru EFR setups - and free ride alongs from Mark Jager at the event for anyone who can make it Last edited by Full-Race Geoff; 09-17-2014 at 04:12 PM. |

Looks like the quicker spooling 6258 would be more up my alley.
How would the 6258 graph look with the if it was the 0.64 A/R IWG option? Sorry, i don't understand enough about EWG/IWG to know what that would mean. The subiefest sale is one reason i'm here looking for more data. I appreciate you guys having a meaningful sale, not just "save $50 on our kit!" |

6258 0.64 a/r IWG is exactly the setup shown in the top graph - it is a great performing setup that spools earlier than stock and delivers a broad powerband. Mark Jager ran that turbo in his street class time attack car previously with excellent results

you mean it spool earlier than stock (VF39) right? ... i'm currently running a stock TD04 @ 19lb for reference.

I'm in the process of building my engine with a 83/74 1.05ewg. I like the sound of my blitz bov and was willing to go raceport bov. So, I'm wondering if anyone tried to run the EFR turbo with and WITHOUT external BOV.. did you lost lot of response/transient spoolup ? ( I'm mainly wondering how effective if the internal BOV actually) I'm running a haltech with map based. thanks guy! |

I only run the internal BPV, it makes the engine bay much simpler and saves weight.

I also only run the internal. I have never had an external so I have no real world experience with them, but fwiw the high boost WG actuator with my 7163 works perfectly. I have my set up posted here.

I.E: With the internal BOV, if you can get instant transient response of 5-10psi and with external, you get an instant 5-7psi. I'm willing to accept this performance drop. However, if by going external, you loose 100% of the transient response then its not worth it. Thanks for your help! I read lots of your threads but never post |

I tested the proto-type Turbosmart 2-port IWG actuator on my EFR6758. It worked great, should be the actuator that comes with the BW turbos IMO.

Just purchased a BW SX-E 8376 for my 06 WRX. deciding on hot side right now. I have a few options.
.63, .70, .88 T3 open depending on who it's from .88 T4 open .91 T4 divided. With a spool valve, and if the spool valve deems not good on our platform, twin scroll. Leaning toward the .91 divided. |
