DIY .... it amazes me completely the lack of ability of owners to do a simple rebuild .... it's not complicated and it doesn't take brains.
Easy peasey if you have the luxury of time and want to know you did a proper job (NOT saying others may not do a proper job, just that the satisfaction of hearing an engine fire that you have had in bits is one of lifes pleasures!)
I would guess a complete rebuild would cost £300 in parts top whack??? Not bad value!!

yeah you are right Pete.
You are guessing. And completely wrong. **** off to some other forum where your *guesses* may be of some value or worth.
Preza si. If you have a bit of mechanical about you they are not that difficult, but its difficult to put a price on it. It wont be just the big end(s) required but there will be a few other things most likely needed (crank, modine, possibly rod, gaskets etc.) if you have ran it for any length of time there could be substantially more damage.
If you dont have a clue-
API
Scoobyclinic
RCM
Zen performance
Extreme scoobies
are all capable (with varying prices) of helping you out.

I reckon I could rebuild my engine for £300 top whack, no need to grind the crank FFS thats why the shells are there - to take the wear
You are clearly NOT an Engineer so, please, don't show yourself up Dear god
DIY is always the way to go if you can - the satisfaction is worth it if nothing else!
But, if you cannot do it yourself, then any of the names listed will do a good job for you - by all accounts, and you could do a lot worse.

Rest assured i WOULD speak to you like that in person.
A gasket set is £300 for starters, most of which you will obviously use in a full rebuild.
"the shells are there to take the wear" -
and you call yourself an engineer - i have said it before, post your qualifications and i will gladly do the same
Pete is right - you will gain immense satisfaction if you DIY it though.

Why have shells then? Your stupidity beggars belief .... why do we not run directly on the crankshaft then, without bearings?

If the shells have worn through or been spat out then a re-grind and oversized shells are needed, other wise yes I would completely agree, why bother! If your going to bother with a regrind then go all the way; get the crank knife-edged and ballenced (allong with lightening the fly wheel and ballencing the two together) to within a nats right bollock..

Most of the big boys will give you a full Warrenty.. But talking of insurance if you spunk £2000+ on an engine re-build make sure you have a settled value with your insurance company because you'll get a shock if you have a prang and they write your car off.

Grinding an impreza crank is a no-no as described in post #95 below. Another thread that Pete's and [davey]'s input was highly useful
http://bbs.scoobynet.co.uk/showthrea...ghlight=plasma
obviously you will have contact between shell and pin in certain situations, but they are not designed to wear. They are coated with a lead alloy to give the best frictional qualities. once you are through this, or its badly scuffed then its game over.
You know that pete surely, stop arguing for arguments sake

I had the same thing happen to me - for what its worth might be an idea putting a short motor in.
a crank regrind is a big no, no.
Where are you based mate?

£300 to rebuild an Impreza engine is ludicrously low. Of the 850 or so rebuilds we've done in 5.5 years, when the shells fail [ as they're supposed to according to you ] they spin within the con rod- big end and wreck the rod and the crank. So a crank every time for £385.00 as a starter.
I won't go on, as l know you're not listening Pete.
