Hello, from Sweden. First post on here!

Impressive build, I envy you =) .

I'm actually looking at doing something similar but on my Seat Leon Cupra 1P.

Unfortunately the needed information to complete the transfer is not really documented or official as you may know. I was hoping that you on here could share some of your knowledge. My intentions are to go with the 2.5L CEPA engine and manual gearbox and keep the FWD to start with. Later on I will look into the task of AWD converting.

I've tried to use google translate to understand all the posts in the thread but that was not successful... Hopefully I can get some guidance on my below thoughts.

1. As I understand you need a TTRS/RS3 ECU or can the existing be reused?
2. Reusing the existing engine wire loom is not an option? An engine wire loom from a TTRS/RS3 is needed? What are the acquired adjustments of the loom or simply plug and play?
3. Will VCDS be sufficient for the needed ECU and module coding or do you need VAS
4. How to handle the immobilizer, deactivate it
5. Is the existing oil radiator and fans sufficient or do you need to upgrade to the TTRS/RS3 to avoid overheating
6. How will an aftermarket 2.0 FSI intercooler cope with the heat
7. Is it possible to reuse the front axle shafts or do you need to go with the TTRS/RS3 version due to difference in fitting to the gearbox
8. Adjustments to fuel lines or Plug and play

Any feedback is welcome.
