Got the FSti back Tuesday after a bottom end re-build and will be running her in for the next few weeks. I am going to follow the re builders instructions per running in but what experiences, recommendations do folks have of this process ?

I did find an earlier 2008 thread on this site ref running in re-built/new engines but it had sooooo many contradicting statements an experiences of what should be done and what defo shouldn't be done etc

Don't thrash and vary the rev range (don't hold at a constant motorway speed)

 

[Pindie]

Like he says but also don't labour the motor either. Avoid short journeys and let it cool completely so everything gets a full heat cycle after the first run or two. Gradually up the anti till your maxing but not thrashing. You do need some revs it short doses and light loads so everything gets properly rubbed. If you too light it can mean you don't get a good contact between things and you'll burn oil.

My STI was a steady build up to full revs and load over a thousand miles.

I have mostly heard the same also. But i have also heard to "drive it like you stole it!" to my thought process and mechanical thinking long constant drive would be a good thing.
My forester when i purchased it was diagnosed with a bad engine because the turbo blew. i replaced flushed a couple of times and ran it around town for a couple hundred miles then drove it 1800 miles in 5 days. 2 13hr nonstop drives. Seems to have reseated everything got rid of valve train noise and if i were to rebuild a motor i would probably try the same trip to break in. But this is just my .02

It was only a bottom end rebuild wasn't it? Most of the above relates to new engines..

Personally, I'd treat it gently for the first 2-300 miles, then just drive normally..

By the way, sorry to hear about the problems you've had, but have to admit I read them with a degree of relief! I also looked at the car you purchased, and only decided against it due to the higher mileage!!

BUGGER, that was a good move you made then considering what's happened !

Yep head gasket first, then the crankshaft and bearings 5 months later ! Its been a financial feckin kick in the teeth but I love the way she drives too much to let her go.

My Subaru specialist have been really fantastic and I cant praise them enough for their valued assistance so a BIG SHOUT OUT to Adam & Jamie at Autotecnica in Buxton

I looked at three other FSTi's before this one. Two 2005's & a 2006 face lift both with 80+K miles but the 2006's both had AST coil overs which I couldn't get a long with and the 2005 had very little history. I only saw one low mileage 2006 black one (that a member on here has just purchased) but when I called it had just gone :icon_cry:
Other than that one I didn't see anymore with less than 75K on the clock in the 6 month period I was looking. Typically all the low mileage ones came up just after I made my purchase !:shrug:

I guess you saw the comprehensive service history and all the receipts. What did you make of the seller ?

Yep, I guess we were looking at the same time, nothing much about for ages, then suddenly everyone was selling... :icon_cry:

I went with a fresh import in the end, 62,000 in English miles! Always a risk as you don't really get much in the way of history, seller had a good Rep though and so far the car's been fine. Got a remap planned in a couple of weeks though, so let's see what the Dyno reveals!!

Your car looked pretty spot on TBH, had everything and looked in very good condition. Seller seemed pretty straight, although he did tell me he wanted something different, I then found out he'd gone after the Foz that I bought, so you never can tell

Hopefully you'll be good to go now and you've got a nice car to hang on to..

Interesting !

I did get the feeling he liked to swap his motors quite regularly but a big reason for selling he stated was due to his new dog. Apparently it was sick if it rode in the Foz so looking for another FSti just doesn't add up :crazy:

I did contact him ref the HG but surprise surprise couldn't get hold of him and he suddenly stopped posting on here !

He did however reply the other month. Apparently he is in the USA now and was looking for another Scooby on here and decided to reply to a PM I sent him back in March. He waffled on a bit but might as well have just said 'tough sh*t'

I know a used private sale is always more risky so one of the reasons I came on here was in the hope of finding an enthusiastic owner with mechanical sympathy both of which I now suspect were absent with this less than honest fellow :shake:

At least you know things are right now. Peace of mind hopefully.

When I picked her up last week the speedo was reading 88888 and guess what my favorite number is ?

I'm taking this as a sign to an end of my shi**y luck lately :woohoo:

 

[mach]

what mileage did she go pop? mine was 76k. mine did same as yours hg first(in warranty) then just out of warranty the bottom end if you trawl the sites it seems a lot of the litcho "330/330" ones(impreza's as well) have eaten theirselves. the power seems to be the "sweet" spot for import pistons etc. to let go on the map/petrol/pressure/power.my mapper did say a few of the scales in the map seemed a bit off(nothing too dramatic kmh-mph/lbs-psi figures but not correct) and mine had been re-mapped some stupid number of times.as for running in 500 miles at varrying loads off boost and allow to warm up and cool down correctly then oil change and enjoy to full potential.best of luck.

Cheers :icon_biggrin:

HG went at 86K

Had the mapping checked and tweaked after the HG's and it was running slightly lean but nothing else significantly out of place

Opted for forged pistons when the HG's were done and also replaced the clutch

200miles to go now before the oil change :Banane35:

 

[mach]

how was your turbo? my engine went pop about 81k.the lean running on mine went worse the higher the rev's due to the scales being out but as with yours not a lot, my thinking being it was so prolonged it could possibly be at least the partial cause. went forged everything just to make sure.i also had a new clutch as it would have been rude not to and with my luck would probably have gone phfut a week later anyway.a.t.b.

8 is a lucky number in chinese so you should consider yourself very lucky.

As James said, at least you know it has been done right now.
