Hello from Bulgaria to everyone! I will show you the story of my baby in more pictures because I do not have good English. It's time for action, take popcorn...

It is time for small upgrades:

New headlights and grille:

The old turbo k03-011 is dead.. It's time for new turbo k03-011 and new clutch SACHS 228mm with a single mass flywheel from VW MK3 Golf 2.0 16V ABF Corrado G60 228mm.

Tires: 225/40/R18 Triangle DOT16
Suspension: TA-Technix (lowering range: 35-65mm)
Coloring a brake calipers in red.

After a while, I realized that this was not my vision(TYPE NFS UNDERGROUND ).. I wanted a clean and classical vision! And the day of embellishment came with a new vision. Some new things on the interior:

And.... Aww Beauty

I installed flashing stops module on my stops(backlights):



Pictures from trips and city rides with friends:

I have achieved the vision and only have to raise the power of the engine in the normal range because the car is FWD.

In short - Setup is:

• Turbo: K04-023 from Audi S3 8l BAM.
• Exhaust manifold: Stock OEM manifold from Audi S3 8l BAM.
• Downpipe: 3" inch 76mm downpipe from SUPER STREET PERFORMANCE.
• Nozzles(Fuel Injectors): 386cc from Audi S3 8L BAM.
• FMIC: Toyosport 550x180x65 (input/output: 2.5" inch 63mm) with a 2.5" inch 63mm pipe kit.

• Turbo intlet pipe: Badger5 80mm V2.2 Billet TIP.
• Maf housing: 2.75" inch 70mm VR6 maf housing.

Front intercooler has been fitted:

And front bumper has been fitted:

And I bought front brakes from Audi S3 8L (312mm - brake discs, brake pads, supplies and brake calipers):

Brake discs are not perfect, but they will become

After about 20 days the rest of the parts must be on the car.. The car soon will be tuned by VAG Service(Sofia, Bulgaria)!

Thank you for your attention. I hope I'm not boring if you have questions - ask!
Good night, guys!

Best engine, best colour ;-)
What Diverter Valve are you using? I hope not a Split-R...

Thank you very much. The old recirculating BOV has been broken. The new blow off valve is Forge 004 dual piston(atmospheric), who does not confuse flow sensor.

I'm afraid that any type of atmospheric dump valve will interfere with the fuelling (provided you use a standard ECU). The fuel is determined by the amount of air entering the system, as measured by the MAF. If you then remove some of that air along the way, this confuses the engine management program. That's why these engines use a Diverter Valve, instead of a blowoff or dump valve; the air never leaves the closed system.

Thanks for the opinion. I'll keep that in mind but even when I bought the car drive with an atmospheric valve and I have not had any problems until now.

Each to their own, but the only cars on here that run well with a dump valve, are those lucky few that have gone MAF-less...
@Prawn 's car is one of those.

It is not a problem for these cars to move with such valves as long as they are good brands (forge motorsport, bailey motorsport, bonalume and etc.)

nice car, but, what's with the wheels? two black spokes? Looks like someone's coloured them in with a permanent marker

Thank you very much. The rims will soon be made, this is their original color, but these two lines are constantly placed by the previous owner. They're cool when they're spinning!

Hello, guys! It's time for a little update on the topic.
The car has been fully serviced [dog-bone mount, belt (reinforced), rollers, water pump, filters, oil, suspension, brakes and etc.].
First he had to change gasket on valve cover..:

Already in Technik Garage(Service) :

During this time I painted the valve cover in black color.

The result with valve cover is more than excellent for me..

Can anyone tell me how to clear the surface of the intake manifold, because I invented something about it ???
I bought and small filter for crankcase vent, because it's taken out into the atmosphere.

Аndddd it's time for the brakes.

312mm from Audi s3 ATE brake pads, brake discs and callipers:

The rims were set..:

Аnd of course a night photo shoot:

There was a slight delay in placing the setup parts. Setup parts will be installed soon...

Best regards - good day from me.

Hello everyone again! At that time, good and bad things happened for the car... The good part is that the parts are already on the car and we managed to turn the rollers on the dyno! The car got out 266 hp/332 nm with 95oct. petrol at 35 degrees outside temperature on 1.3bar. This result made me really happy, but not for long. Week after setup(remap) on the car, in the evening I decided to drive the car and from a third gear to fourth I scored second gear at 7050 rpm, which happened by mistake.... The damage was almost clear, that she hit the valves on the head. In fact, it was the bad news..
We will now open the engine and understand what the damage is. Here are some pictures of the parts and the car

New rear muffler from Sebring with dual tip.

On the runway in Sliven, Bulgaria (watching Drag Racing Bulgaria)

Few pictures from the project

The new injectors are now in their place..

And the exhaust manifold and turbo were already in the basket, but I having problems installing my badger5 v2.2 tip, which was obviously for the right steering wheel. Still, I found a solution..

Making of downpipe

I managed to buy a shield for air filter

I decided to fix the ic pipes over the engine of 2.5" inch (63mm) before remap..

Too much powaaah..

Аnd the end result of the engine is more than satisfactory for me

New electronic boost controller from LDPerformance

Here's the big setup day:

Dyno graph:

Time for bath

With her sister (the little one s3 & the big one s3)

One video of the car



The time has come for the day that is bad for me .. I would like to thank my friend, who immediately helped me to take the car in home

That's for now. Once there is development I will write what happened to the engine.. Good night, guys
