	AGU head on AUQ block « on: June 25, 2022, 10:06:16 AM »

Hello ppl,

I am just giving a chance to restore an 8L here in Brazil - the AUQ head height is lower than the minimum, so, I will have to change it.

There is a lot of AGU heads available for buying, but not even one AUQ. I just found that AGU would fit, but how about the VVT and cams?

If someone already did that, please tell me

Thanks!

Fits fine. Swap VVT unit if you want to keep it.

Some tuning might be required as the AGU is a big port head. Physically it will work though.

Thanks everyone!

Updating because I didn’t find it in anywhere:

One day after the post, I just found an AWT head (from Passat, with VVT).

The main problem: Passat engine is longitudinal, A3 engine is transverse - so I will have to adapt the intake and exhaust manifolds.

In your opinion - does it worth the pain to adapt these or finding an AGU/AUQ is better?

Thx!

Manifolds are bolt on indeed, but do I remember wrong that some tinkering was needed elsewhere?
I remember that it was not completely plug and play for some reason, but it was a very long time ago.

Different mounting size for the fuel injectors - spacers or machining required

Hi. I'm from Brazil too.
I have an BAM head, taken out from an 2002 S3. Small port, with VVT.
PM if you have interest.

There's timing belt/pulley offset difference between 058 (longitudinal only) and 06A (mounted both ways) engines. Other than that, SAI and VVT I dont recall anything else that would not let to swap the heads p&p.
About year ago I swapped bare BFB engine from B7 A4 into 8L A3 by only cleaning some previously unused threads in the block and bolting over everything Roll Eyes
