I'm looking at a used 2002 X Star tomorrow and am interested in the differences between the 310hp TBI motor and the 350hp MPI motor (both 5.7l). <BR> <BR>Specifically, difference in mileage, cold starting, smoothness, hole shot, top end, and maintenance requirements. Anyone have experience with both of these motors? <BR> <BR>

john, <BR> <BR>mastercraft offered 2 5.7's in 2002, a 310hp and a 330hp. I can go on and on about the differences but it might be easier for you to give me a call at cope's in santa clara. <BR>408-248-7844

make sure and ask if it is prop horsepower or flywheel horsepower!!!!

John I was told that the 310hp was a far better motor out of the hole. The 330hp motor had a better top speed but was more sluggish out of the hole that the 310hp. I went with the 310 and it's a great motor. Thats why MC went with the new 350hp engine in the 03 lineup. It's suppose to be a great motor with better torque and a higher end than the 310 and the old 330.
