I'am looking at buying a mini cooper s engine that has been in a historic rally car at some point and has been taken out stripped down and ready for rebuilding, here is the description:
MINI COOPER S ENGINE
REMOVED FROM HISTORIC RALLY CAR

COOPER S AEG 312 BLOCK OVER BORED TO 1380

3.5 OMEGA PISTONS

POLISHED COOPER S RODS

1.5 COOPER S FORGED ROCKERS

SWIFT TUNE SW5 CAM

AEG 480 COOPER S CRANK (EN 40 B)

ULTRA LIGHTENED FLYWHEEL AND BACK PLATE

COOPER S 12G940..1805 HEAD (STANDARD HEAD)

4 SYNCRO REMOTE STRAIGHT CUT GEARBOX IN EXCELLENT CONDITION HAVING HAD VERY LITTLE USE

ALL PARTS HAVE BEEN CHEMICALLY CLEANED AND PAINTED READY FOR REASSEMBLING

The question that i have is how much stronger would this engine be compared to an MG metro A+ engine that has been bored out to the same spec, aslo what should i be looking for when buying?

[jaydee]

Really depending on who have build the engine, by the way it should be stronger than a mg metro engine.
Swap the sw05 cam for something more adeguate..like a 544..

[mk3 Cooper S]

The block is on it's last bore.
Do you know what the grind of the crank is on?

What year mini are you planning to fit it to? The remote gearbox and linkage will require modifications to fit it to a post 74 ish car.

Depends on price to give a good assesment of value really.

Not sure about this seller as I have heard some rumblings but doesn't look too expensive if it is as described.

It was what I picked up from a thread on here.

Something to do with feedback from another account of a very simular name that did not have good feedback. Eluding to bumping up feedback from the same origin of ebay account or something like that???
I.E starting up another ebay account of a simular name to shake off the bad feedback stigma?

All above comments are allegid and hearsay and picked up from opinions only.

As with any ebay sale it is buyer beware with all transactions.

[feybrand]

nicely worded i think
thanks for that

i would not touch these guys with a barge pole.honestly.

[west11]

Do you think it is worth taking a punt on it at a grand. I was goin to pick it up myself and have it rebuilt by somebody else that has a good reputation. I a had heard these rumours and yes it is the one that you are on about. they are the only thing that is putting me off at the moment.

[shorty]

1000 and its not even built up for you as that costs an extra 375 quid

way to much money in my eyes, but each to their own opinions

[Guess-Works.com]

It's a 3 synchro box for a start...

maybe worth asking what the gearbox case number is...

[mk3 Cooper S]

Iwould ask lots of questions about the size of the crank , bores etc.

Then measure everything when you get there, If it is not as the answers and you don't like anything you could walk away stating that "it is not as described".

Condition of crank and block are key for me at that price,
Not sure that you can do anything with an offset bore 1380 when the bores wear?
The gearbox has a value too so do the maths on what the components are worth.

[bmcecosse]

The block may very well be porous at that overbore. Cooper S forged rockers are NOT 1.5 ratio. The 940 head was only fitted to the very last S engines - it's NOT the REAL S head!

[welshdan]

i would look at getting a decent 1275 lump and building it up with an overbore etc, to the spec you are wanting. as said the block is on its last bore and crank is unknown. buying used is always an unknown.
