What would be the benefit of a full replacement 2.8L over rebuilding the 300Tdi and upgrading the turbo the Variable one and going a bigger rad/intercooler? Will this leave me with more space in the engine bay? Will it help keep cool?
Is a good rebuild be like getting a new engine? Or is it just going to slightly prolong its life? (engine seems to run fine now but has almost 340K’s and i have little history on it)
