Picked up a JD 4045T 115HP engine. 4cyl 4.5L top mounted turbo. Looks like it will fit, with turbo remounted to side. Quick search shows it weighs about 100lbs more than a 6.5. My Blazer is lifted w/HD front leafs, so front sump should clear. Comments and suggestions....does this swap make sense (vs a 6.5TD) ?
