ws95 Posted May 26, 2020 Share Posted May 26, 2020 Looking to change my 2004 a4 b6 1.9tdi engine and gearbox to a much larger engine. What engine choices have I got to choose from? 3.0tdi? 2.5tdi? Any help is much appreciated. Quote Link to comment Share on other sites More sharing options...
Steve Q Posted May 27, 2020 Share Posted May 27, 2020 My advice would be to get your current engine remapped. You'll find the 1.9 can be made to produce more power than the 2.5tdi. I have the 2.5tdi in my a6 and power really can't go above 180bhp. Cheers Steve Quote Link to comment Share on other sites More sharing options...
