S3 engine change

[Scoot123]

Hi there new to this forum. I have a 2001 s3 Amk engine,bought a replacement over the net,when it arrived there is no Amk stamp on block ? Seller assures me it is a Amk,is there any differences with the bam or the apy engines,it looks the same as my Amk ,but don't want to it it then run into problems ?

Ask him for the VIN of the car it came from so you can verify through Audi what it was (assuming he gives you the right one) but there should be an engine code somewhere which would be the quicker way to confirm - if not be wary as to where he obtained it from !!

Look on the block flywheel end... the engine number should be dot imprinted on the edge of the block where the gearbox fits...

If it is not a Amk will it still fit looks same as my amk

Why don't you just check before panicking as it may well be what you ordered

 

[Scoot123]

I have already had a good look and can't make engine number out ? Ment to be fitting it tommorow !

 

[<tuffty/>]

use some wet and dry to rub over the top to clean it up...

<tuffty/>

 

[brasiliangringo]

Get some petrol on a rag and give it a good clean..

 

[Scoot123]

If it is another engine as in a bam or apy will it fit ?&nbsp;

Yes mate, only problem is the apy is narrowband were as your amk and bam's are wideband.

 

[<tuffty/>]

For reference you will find the engine number in the area I have marked in red (thanks to Stacey for the pic... even if he doesn't know yet ;P)

You can use a BAM, AMK, APY from an S3... you can use a APX, BAM from a TT, AMK, BAM from an LCR... there are a few other 20mm pinned bottom ends you can use (AGU and whatever the Mk3 Ibiza Cupra is but they use 9.5:1 comp ratio rather than 9:1 of the 210/225's)

Check the number first... I assume this is a short motor as the engine code is also on the head...

Doesn't matter when its just the bare engine dude...

What does that mean

 

[Scoot123]

Thanks tuffty, cylinder head with engine so I can get a number off head ?

 

[<tuffty/>]

What does that mean

It means nothing in context of what you are doing... ignore him.... bad lad Dani!! ;P

...but to clarify... the S3's with APY engine codes used an older ECU to the AMK... this makes no difference in your case as all you are doing is swapping the bottom end... (I am assuming this of course as you have not said otherwise)

Where you could have problems is if its a complete APY you are trying to swap then there are differences on the head... APY has secondary air injection, was non VVT and a different cam cover..

What exactly is it you are trying to fit? the whole engine or just the bottom end?

...and have you sorted that engine number out yet?

A few pics of the engine would help too

<tuffty/>

 

[Scoot123]

It's full engine I am fitting .head looks same and injectors are the same !

Argh good point sir, it was just in case he decide to do a full block and head swap .

 

[<tuffty/>]

The head will have the engine code on a tab...

Find out these codes and/or take pics... can't help you any other way really...

Does the new head have a VVT tensioner?

ye that's we're it says Amk on old block but new one blank there ? That's we're I am doubting the engine but everything looks same as old engine

 

[<tuffty/>]

Have you managed to get the engine number off the block yet? its not uncommon for the engine code to be machined off as it could be a fairly generic engine... I wouldn't want to fit it without knowing for sure as there are differnces that could compromise the engine in the case of an S3...

Lmfao, i do The exact same thing mate so your not alone.

 

[aragorn]

Audi refurb heads dont have anything on that tab.

The engine number should be on the edge of the block as mentioned above.

Thats why I fill my build thread full of pictures for you guys ;P

<tuffty/>

 

[Scoot123]

Will try clean block and get engine number tommorow,thank guys.

 

[Scoot123]

That's the engine in and sounding nice,hopefully have it out on a test drive tommorow,thanks guys.

 

[<tuffty/>]

Did you find out what engine code it was?

<tuffty/>

 

[Scoot123]

The diference on the compressor ratio is made only by the piston?

Yes

[Miguel_S#]

its a good ideia in a apx engine swap 9.0:1 piston to 9.5:1???
