Tuning guide for 1.8T AEB engines with 150 PS
Up to 320 PS: How to tune your 1.8T engine with code AEB
Professional tuning in four stages for AEB engines
So, you’d finally like to get to grips with your engine’s performance, and find out what 320 hp feels like? That’s precisely why we’ve written the tuning guide for all 1.8T engines with code AEB. Here, we show you how to professionally tune your Passat or A4 in four stages. You’ll also find out all the products you need, and get valuable tips from Bartek personally.
Installed in:
- VW Passat B5 (Typ 3B)
- Audi A4 B6 (Typ 8E)
- Audi A6 C5 (Typ 4B)
Year of manufacture:
1998 – 2005
Engine Code:
- AEB
The parts listed below should also fit in the largely identical engines ADR, ANB, APT, APU, ARG, ATW and AFY with an output between 115 and 150 hp.
Stage 1
increased efficiency:
+ 40 hp
+ 100 Nm
Final output:
190 hp
310 Nm
You need that extra, so it lasts a long time:
Here you do not need any additional components. Just install and have fun! Do not use longlife oil. Better is our oil.
BAR-TEK® TIP!
We recommend to refuel 102 octane fuel. This gives your engine more power because it knocks less! The turbocharger should not be too old and the engine should be in good condition. The base must be right.

Stage 2
increased efficiency:
+ 55 hp
+ 110 Nm
Final output:
205 hp
320 Nm
You need that extra, so it lasts a long time:
To bring the extra power on the road, you need a sport clutch. If you build our RS Turbo, you can drive even more power and the turbo lasts much longer than the normal K04, as it can not transmit the power. For the conversion to K04-015 turbocharger you have to install a racing cat and our upgrade air mass meter.
BAR-TEK® TIP!
If you already have a Sportkat, a suction hose and an upgrade intercooler installed, you can use it again. The Sportkat is very important for the 1.8T engines in the Passat and Audi A4. Because the catalytic converter sits just behind the turbocharger, the exhaust gas temperature is too high. Our Sportkat upgrade prevents this and lowers the temperature with less exhaust backpressure. If you want to land at 250 hp, order directly the Tuning Kit Level 3!

BAR-TEK® TIP!
With the tuning kit level 3 you have the extended development of kit 2. Here you have 380cc injectors and an upgrade manifold and a further optimized software! If you already have a Sportkat, intake hose and an upgrade intercooler installed, you can continue to use it. With a large intercooler you have the complete power available in the summer!

increased efficiency:

Final output:
320 hp
400 Nm

320 hp: This is an announcement! To drive this performance, you'll need to replace your connecting rods with H-shaft connecting rods. So that then the 320 hp also get on the road, a sports clutch kit is required. The exhaust must be a 76 mm exhaust system. The fuel pump should be the upgrade version, otherwise motor death threatens by leaning.
BAR-TEK® TIP!
This conversion requires good software tuning. You can send us your ECU or have your vehicle tuned directly in our workshop. Another tip from us: You should build the downpipe in 70 mm, as it is very narrow at the Passat and Audi A4 below the axle body to the body. You should put the catalyst down. This reduces the exhaust gas temperature and protects the turbocharger!

This is how you improve the cooling:
If you want to get the full performance out of your engine, you must not forget the cooling. Even a little extra power puts a lot of strain on your engine! The thermal load increases and affects all areas of your vehicle, even the transmission suffers from the new power. At best, the hard-earned power is reduced again; at worst, your engine suffers major damage. So that you can tune your engine safely and reliably, we provide you with everything you need for perfect cooling. Although it is ideal to install all parts together in a cooling bundle, you don't necessarily have to order everything at once. Each product helps you to improve cooling.

The perfect turbocharger for your tuning project
The turbocharger is one of the most important tuning measures of all, as there is huge performance potential in the compression ratio. This is why you will find all the turbos from the guides and suitable alternatives in this special turbo guide, for example if you prefer a specific manufacturer. We have also compiled a lot of information for you on the subject of turbochargers, which you should take a look at. In addition to the detailed turbo tips, there is a page on running in engines correctly, turbo lag and, of course, our 14 turbo rules.
