Must be a reason most people go with the VW diesel engine for a diesel conversion? Ive went up 3 tire sizes and seems to curb my top speed to 75mph and at that its lowered 3 inches. Its more of a dog to drive too, but its great in the white stuff.
Maybe they have something on the power block on spike tv? They do a lot of suzuki stuff and it shares a lot with the other models.
