Audi Cabrio 1Z Engine Problems - More Power?

Greetings from the far north.
Here's a brief introduction: I've been a mechanic for over 25 years, and in my free time, I mainly work on restoring and modifying VW T1 buses. Professionally, my career has led me to work with buses, specifically those equipped with Iveco engines.
So, I'm a little bit of an expert in the field.

My everyday car recently spilled its entire oil supply all over the engine compartment.
It's a 1995 Audi Cabrio B5 with a 1Z engine.
Now, I wanted to install a new engine, preferably one with 110 horsepower.
The old engine had some acceleration jerks, which I attributed to a worn-out ESP (Electronic Stability Program).
I understand that I need to implant everything, including the control unit, but I don't want to proceed blindly without knowing what to expect.
My engine control unit still has a boost pressure connection, and I don't want to modify my dashboard.
Could I, for example, take a 1999 A4 with, say, 110 horsepower and strip it for parts?
Surely, someone here has done something like this before.

My search in the forum didn't get me any further after an hour.
Maybe something like that already exists here.

Thank you, Arne.

Sure, it's possible! You don't need to modify the dashboard. The best option is to use the AFN engine from a Passat or Audi, as the transversely mounted engine doesn't have the threaded holes on the left side for the corresponding engine mount.
However, it is possible to create threads yourself.

The A/C compressor bracket is different for the transverse engine - you can take it from your 1Z engine. It's possible that the clutch and dual-mass flywheel (DMF) from the AFN engine won't fit into the 1Z gearbox - check if the clutch fits the gearbox input shaft and if there's enough space for the DMF.

The exhaust flange from the 1Z engine doesn't fit the AFN flange. You either need to modify it yourself or replace the entire exhaust system with one from a model that originally came with an AFN engine.

It's possible that the lower lateral cutaneous nerve of the anterior thigh (LLK) is larger/thicker than that of the 1Z zone. If it is, then consider adopting the approach used for the 1Z zone.

Ideally, you should use a MSTG (Multi-Sensor Technology Gateway) that supports the specific sensor type. Similar to your internal LD (Laser Distance) sensor, there are older models and newer models with external LD sensors. However, it's not overly complicated; you can simply route the cable for the external LD sensor correctly, or even easier, transplant the entire wiring harness.

Hi,

Here should be the information that is relevant to you.

Best regards, Michael.

I just read the link, and it doesn't even mention WHICH car the engine came from; I suspect it's a transverse installation! If you have the opportunity to compare the same Audi model with the AFN engine under the hood to your 1Z, that would be very helpful! Or, there might be pictures available online.
Unfortunately, I can't remember everywhere I've been working and adjusting things.

Hi,

AFN engine from A4 B5 (identical to Passat 3B) into Audi 80 B4/Type 89 Cabrio with 1Z transmission.

both are mounted lengthwise at the front .

...otherwise, the engine mount wouldn't fit.
