1st head gasket, now big end! doh
 

the scoob hasx now developed a serious rattle around 3000rpm. im assuming the big ends has gone.

any suggestions as what would be the most easy and cost effective way of fix, either sorting this engine out or drop another one in!

what has to be done?

looking at previous threads it mentions that the crank and other parts needing regrinding!

also another thread mentions eddie torrens having a few engines lying around! any update on this.

thnks

one option is an sti steel crank mate - in my opinion see michael white.

now - stevie for once do ya agree? lol!

infact price it with OMA. AI and ECC and let us know what reponse you get.

or

try DS Autos in antrim - they so lots aswell.

cheapest is probably source a replacement engine....but then you are in the territory, of not knowing anything about the engines history.
So it may work out great...or it may not.

Re-building is probably best...but not the cheapest. But at least you know what you are getting.

At a minimum, it will likely need crank, rods, bearings, oil pump and possibly oil cooler too, as well as typical rebuild gaskets etc.

There comes a point, when a 2.5 is an option worth considering, although that then entails ecu work....or more likely a replacement ecu given lack of Ecutek availability for older models.
So that bumps the 2.5 option up a bit further in terms of cost.

All the cranks are steel ;)

But new model STI cranks are tougher, and have better oilway drillings...but slightly more expensive than regular cranks.

wahoo! stevie for president!

and...

just wot OMA told me, michaels doin my mates as we speak.

He'll have said the same thing as me.

later STi 8/9 cranks are rear thrust so you will need doner block from 99 on to go this option.......

have decided to source out a block

anyone know of any used or reconditioned lying around for good money?

sorry to butt in on your thread, but approx how much is a rebuild ish?

i`m praying to god i never need one, but i`m curious

Depends on damage, and work carried out/items replaced during re-build.

It aint cheap either way. Even if you have been lucky, and damage is minimal...expect £1k+ as a starting point as an absolute minimum for a big end damage rebuild, but likely it will be a lot more.

Even basic parts alone during a rebuild....bearings, oil pump, head gaskets, oil, plugs, belt etc dont come cheap, nevermind what is required to rectify the damaged crank/rods, if the big ends have **** themselves.

If you've only melted or damaged pistons etc.....there is a lot less work involved, so that may be cheaper...but then it depends on cost of replacement pistons, and if the bores have been damaged. Sometimes you can end up needing a re-bore and full set of pistons.

So its easy to see why a replacement engine from a breakers can look tempting. But it is most definately not always the best choice, especially if you intend to keep the car.

holy good lord.

fingers crossed then.

its due a service in november, so i`ll get it up to OMA probably and get them to give her the once over while shes there

New cranks are suprisingly cheap from Subaru, plenty of upgraded rods and pistons on the market too. You really need to look at the whole picture and decide if a 2,0 rebuild or a new Subaru 2.5 unit best suits your needs. Either way you will need an oil pump, oil modene, new sump, headgaskets,timing belt and tensioners, seals etc etc plus all labour costs. Chances are you fit a new cluch kit as well before your finished.
All in all to do it right youll probably spend 3k. o r if your really lucky youll find a low mileage new age engine and save a lot of hassle.
Either way deep pockets are required.

Not a big fan of the 2.5 engines, seem a bit troublesome. Currently building a closed deck 2 litre. Using an '04 crank, which I bought straight from subaru, was the cheapest. The block I got from an earlier car, and had machined to accept the different thrust bearing location. Eagle Rods and Wiseco pistons I got from E.C.C.

Should be a lively little number when she's done. Then i'll give ya race scubbay. Can I still have that head start?????

If using a regular non-sti crank, it would have been a lot less hassle just to buy the correct crank for the old centre thrust block, rather than machining a newer block.

Although if it was me, given costs involved if the engine really was damaged badly, I'd prefer the 2.5 option. It will likely be more expensive, but you are getting more for the money.

Cant get away from that old saying...aint no replacement for displacement etc etc ( although boost does help :P )

Properly built 2.5 engines I'll agree with. But I know of two 2.5 litre engines in the 2006 STi's that have scrapped themselves for no apparent reason, in less than 10,000 miles. I'm just not convinced.

ive been gettingf a lot of quotes from various companies ranging from 450 for just block with 41k miles, upto 1000 for reconditioned block and ancilliaries.

Now I would really like an EXACT breakdown of that reconditioned engine and ancilliaries for £1k.


And a block for £450 isnt much use without a crank, some rods, and maybe a few pistons. Bearings also help..... And its a bonus if its built too !

New 2.5 short engine £1450 from me. Delivery in 5 working days or 2.5 with head gaskets, new oil pump. new sump £1700. Ive done a few of these and can even give you a spin in one. Management and turbo upgrade are advisable too though. Advice is free everything else you gotta pay me!!
