dont redline it lol keep out of full boost and under 4500 rpms. I usually change the oil after 500-800 miles then again after 1500.

 

Lies, well except for the changing the oil part...

Drive it like you want to. Give it boost and rpms, let it cool down with some low load cruising, repeat.

The key lies in giving it varied rpm's and loading to get the rings to seat properly. I drove my car the day I do today when it had 7 miles on it and it burns ZERO oil (not exaggerating). The only real purpose of a break in is to seat the rings and break in the new clutch. Rings are good in the first few miles, and just dont put the power on until the clutch is completely engaged so it's not slipping and getting glazed.

 

im also a owner of a 11 WRX. i hear many different things about breaking in the engine.granny the engine. don't do 70 mph +, keep below 3000 rpm and take it easy for the first 3000 miles.then another source said drive it normally how u think u would. i think i damn near red line it a few time. i stall a few time out of embarrassment i put the pedal down not sure if i hit red line or not. one time i know for sure got up to 7000 and freak and let go of the pedal. so i sort of did the second method. i should get my oil change soon im close to the 1500 mi mark.

 

that may be true with subarus...ive never broke in a subaru engine..but I know on the race motors we build that put out anywhere from 400-700 hp are broke in either on an engine stand or idling at different rpm's for long periods of time which would be impossible in your case...and when you change the oil for the first time you will almost always find tiny shavings, which is normal. My buddy bought a wrx with 35000 miles on it which were driven by an older woman, and ended up blowing the car up at 40000 so maybe the way a subaru is first driven off the lot is the way it should always be driven?

 

keep in mind when you're talking about break-ins that although there is some truth to the "drive it like you intend to drive it" from your engine's point of view, your clutch needs a more gradual brake-in, as do your brakes. The brakes take about 50 miles, ideally not stopping too hard. The clutch is about 300 miles, ideally not using much gas unless it's fully disengaged.

 

^Just need to bed in the brakes and they're all set after a few miles.

I just picked up my 12' and waited until 50 miles to redline it.

 

Yeah, break in is much different on newer cars with smaller hatching and much finer tolerances. I would take it to 5kish once under a pretty hard rev, not just letting it spin but seating the rings. After that run it easy, because you will have very fine peices of metal in your first oil change from the break in, you really don't want that flying around in your motor at high revs.
Seat the rings and drive it easy for 3000 miles or so.
