Hi. I do not use one but had many oil mods done to the motor. What level mod did thet do? I did not see a 1441kit. But did see a street 1600cc kit. The turbos are easy on the motors compairded to am NA motor. As I will make an easy 400 on street trim it will be a littly lazy down low but just chang the gearing for street. I will drop down to a 16 or 17 fron my 20 with my 34 rear. Hope they put in an HD input shaft.
