Next spring I'm planning an engine swap from my 85 N/A to either a 4agze, then turboing it, or a 3sgte (I am having a shop do it, though not sure which one). The only problem is will the 3sgte be easy enough to service? or is it worth it to spend the extra cash and switch a 4agze to a turbo setup? I know both engines can handle the horsepower i plan on pushing, but for less money it seems i can have a 3sgte swapped. What's the weight difference between the two as well?
