I just noticed that the price difference between Borg Warner EFR and the older Borg Airwerks 67mm is not so big (around 300e) so i am wondering if is worth the "upgrade" currently i did not found any dyno on efr9180 on 2.2 / 2.5 engine . The compressor seems to be same / close spec .. the hotside is better (newer tech) on EFR. I am not sure about reliability ?
