Hi guys, I was hoping to get some advice on an A3 1.8 turbo conversion in an A3 1.6. I understand that most people would probably advise just trading the 1.6 in and buying a 1.8 but this particular car has a lot of value to me, it's absolutely immaculate and I know it's been very well looked after from new. To add to this, I'm able to buy a 1.8 turbo engine for pretty cheap and I wouldn't find the engine swap particularly hard assuming it's straight forward. Could anyone who's done this/ a similar project give me any advice? how much exactly will I need to swap out? obviously I'd need to fit the new engine with a turbo and mount and inter-cooler as but what else? new ECU? do the 1.6 exhaust headers fit the 1.8 engine or would I have to change the exhaust system too? what about the speedometer? (I'd like to keep my own unless absolutely necessary as they verify very low mileage). I'd appreciate any advice from those of you who know what you're talking about in regards to this. Thanks!
