Ok so the single 6-rib LCP for the '15 WRX won't fit on our cars, but... The more common 2 belt pulley will. "But Dave! We only have one belt, and it's got 6 ribs!" So? I've been running a 5 rib belt (a NAPA 25050650) for the past few months as an experiment. I haven't had an issue yet, regardless of alternator load, hitting the steering lock, etc. So... I put this baby on with my 5 rib belt. The 5 ribs on the pulley line up with the 5 forward-most ribs on the accessories. Went from 5lbs 11oz to 1lb 4oz (2590g to 565g). http://i.imgur.com/kxa23GL.jpg

Well, it seems someone at Perrin didn't check. The pulley is wrong in so many ways (center hole is too small, uses a dowel instead of a key, rib location way too close to engine, etc). It's going back (and I still don't think this guy at Perrin knows what he's talking about, let alone comprehending what I'm telling him).

I think this should also mean that if anyone else makes one for an NA '12-14 Impreza or the '15 WRX, or the '13+ BRZ, that would work too (that's the application for the Perrin).

Solved! I saw a '15 WRX the other day, and noticed his crank pulley LOOKED just like ours. I then saw that Perrin has one for the '15 WRX, but doesn't list one for '10-'12 LGT. I asked, and just got a reply. "...The PERRIN PSP-ENG-101 crank pulley will work on your Legacy just fine. We just don't have an application for that car on our website yet..."

I've been looking for a lightweight crank pulley. I think I've finally found a solution. The 2013+ BRZ pulley looks the same as ours. Can anyone confirm they're the same part number? There are several outfits that make a lightweight crank pulley for the BRZ.

Bunky, it's a 2010, bought it new.
