Audi A3 8P 1.8TFSi 160hp (IHI upgrade from G6 Gti) 241whp & 429nm

Postby Etuners SA » Wed Feb 18, 2015 8:30 am

Hey guys

Just wanted to share some information on this conversion.

The Audi A3 8P 1.8TFSi (160hp) has the EA888 motor with a smaller displacement then the Golf 6 Gti, Apart from the injectors and turbo.

Turbo on the A3 is a very small Borg Warner K03 which suffers at our JHB altitude.. Boost levels of around 1.1bar spike and holding around 0.5bar at 6000rpm with our Etuners stage 2 ECU remap where we found the turbo maxed out.

After strapping it to our dyno she made a healthy 197whp and 312nm on our dyno with stock turbo, Etuners intake, downpipe & Etuners Stage 2 software.

I spoke to the customer and advised on the turbo from a Golf 6 Gti (IHI) which is a direct bolt on for this engine as its from the same family (EA888)

Car was brought in and we installed the turbo. Complete bolt on. Revised Etuners custom file was loaded and we strapped her onto the dyno.
A few logging sessions and the outcome is outstanding.

We managed to get 241whp and 429nm with the revised file. This is a massive gain and is a testament to how underrated these 1.8TFSi motors really are! Proof of the 1.8TFSi's being a great platform for tuning with the correct hardware mods.

Dyno sheet of before and after below and a couple of pics of the stock turbo and IHI turbo.

This is a relatively inexpensive mod as IHI turbo's are freely available these days at reasonable prices.

That is awesome work... Seems to be in stage 2 golf 6 territory? What do G6s make on your dyno?

Yes, Golf 6 Gti's make more or less the same on our dyno.

Fantastic little engine!

Well done E-tuners and Filipe.

I was speechless when he sent me the figures and the dyno.

That is some mighty impressive stuff for the 1.8TFSI. They are really impressive.

There is still more to get out of this car 8-)

Although some 18s or 19s better be next on the list :tongue:

If the IHI turbo is direct bolt on then would I be correct in saying that a K04 modified to fit G6 would also fit the 1.8TFSI? Although I think for the money spent on the turbo and the gains made, its a bargain of note.

Yes, the K04 is bolt on but requires stronger rods and larger injectors.

The 1.8TFSi injectors are good for around 300hp though but thats at the limit.

Heat soak and intake temps are as before. No large change. Stock cooling is sufficient.
