i can get one for 300$ for my 325i '92. thats what this mechanic told me when i went to get my a/c fixed. i had forgotten but this reminds me, i wanna start thinking about again.
the guy told me 190hp to 205 and 188 ft-lb to 201. but he said the max hp only goes up about 15hp but that at lower on the rev range the gain is more than 15 which is where the car needs it. bc my car is sluggish in 1st and 2nd but after 3rd woah nothing stoping it.
