Speedster With Tt Motor “!

Hello Ride a Speedster 2.2 147ps I am quite satisfied with the car, although I do not drive it regularly, just when nice weather is. I have been playing for a long time with the idea to install a 1.8T engine with my Speedster 1.8T 225 Ps which if I bought it of course does not remain in the original condition. I think so 300-310ps should be it already. I would then come to a power weight of approx. 2.8 kg per ps …..:-) I would get the engine for 1800EUR with approx. 50 000KM including gearboxes. My question to you, what keeps me busy. The drive shafts of the engine of the 1.8T are of course different and longer than those of the Speedster. How do I fix such a problem?? I mean, if I have the motor installed, where do I get the appropriate drive shafts which then fit with my car, or do I have adapter plates or extensions? and how does it work with the electronics when I have the control unit of the 1.8T that must be on the electric nik to be voted on (Tacho flasher light….. Not misunderstood, I am not untalented, and would also pass the conversion, but these questions just don’t leave me rest. and ps. OK it’s an Audi engine, but I get it cheap now, and since I myself am 1.8 dangers I know how tuning joyous the engine is. I ask for your answers, but please only those who understand what is built by such.
