8V A3 1.4 to 2.0 Conversion

[JaiR]

Hey guys I'm contemplating buying a 2018 a3 Sportback but after driving one I'm not really impressed with the the power. I was wondering if once I bought it I would be able to swap out the 1.4 to the stronger 2.0 engine, not the one on the S3 but the one that's another option for the a3.


Before you comment "buy a 2.0 a3!" Or "Buy an S3" you have to understand where I live. A 2018 A3 1.4 here costs around 40,000 us dollars because of our taxes. Recently an S3 was imported at a cost of 120,000 and I'm not planning on paying that kind of money. So please don't tell me to buy another car just let me know if anything like this may be possible. I'm okay with spending up to half the price of the vehicle. Thanks in advance for your help.

Which 1.4 are you looking at? The most powerful is 150bhp, and IMHO uquite lively. You can also get it remapped to be over 190bhp. Much much cheaper than changing engines.

 

[JaiR]

I believe it is 148hp. In terms of remaps I don't know any good places here but do you know any tuning "chips" or tuning "boxes" that you could recommend?

 

[Mikeso51]

I have no personal experience, but DTUK tuning boxes get good write-ups. A box for the 1.4tfsi 150 bhp engine claims a 35 bhp power increase for around £400. Others on the forum can probably advise you regarding remapping companies.

Start with: where are you from? What will a 2.0(you're talking about the 2.0 turbocharged engine) cost complete with wiring loom, ECU, all ancillaries? Can you do the swap yourself? do you have access to VCDS for coding?

I have had, and still have, DTUK tuning boxes and they're a very good product. @ABYSS is a AS site sponsor and happy to answer any of your questions. I still have the one I had fitted to my 140ps 1.4 A3 saloon and it certainly makes a difference with the torque increase...

I have an H&P Motortuning Powerbox on my 1.4TFSI (150Hp). It gives extra 36Hp and 60Nm of torque. Makes the car very nice to drive.

Is yours a cod engine?

 

[makelja]

Yes it is. CZEA is the engine code.

 

[dg-1984]

How did you find the engine for COD function after remap? Is yours a manual? If so did the clutch hold up with extra torque?
What year and mileage has you car done.
Mine is a 14 plate with 30k on it and was wondering about mapping.

 

[dmpx]

I had a remap on my A3 1.4 COD engine - The COD worked perfectly after the remap and the clutch never missed a beat.

Mine had 108k on it when I sold it. Brilliant little engine imo.

 

[Mikeso51]

Dmpx. That’s very interesting. If you don’t mind me asking, who did the remap, and how did it compare with the £400 cost of a tuning box?

 

[dmpx]

I had a local tuning company in Belfast do the tune for approx £280 incl. dyno runs.

It went from 141bhp to 187bhp on the final version of the map. It transformed the car tbh

 

[Mikeso51]

Thanks. Very impressive performance improvement at very reasonable cost. Definitely on the list for when my warranty runs out!

Just a pity that your tuner is across the water from me.

 

[makelja]

Mine is S-Tronic. And the clutch hold well. No problems so far.
Mine is 2017 and 32k km on the meter. Just out of warranty in April.

Was yours a manual?

 

[dmpx]

Was yours a manual?

Yep. 2014 manual saloon S-Line

 

[dg-1984]

Yep. 2014 manual saloon S-Line

Excellent thanks that's good news, no issues with clutch slipping or anything?

 

[dmpx]

Not even a hint - Car ran better than before the remap right up until I sold it.

Better powerband, more torque and better MPG.

Just checked out the site and for roughly £250 seems pretty good. Are they easy to fit? And do they come with just one map or are they switchable?

Takes about 10min to install. Need to remove the airfilter box from the side which is closer to the front. But if you have small hands then that is not needed. I placed the PowerBox between battery and the suspension mount.
There is only one map.
This is my third PowerBox from same supplier. Always been happy with them in different cars. Better than RaceChip, which I have had one.
