My engine is going to be rebuilt. So, I'd like to ask a few question:

Do you think it's worthwhile to rebuild a 3MZ?
Where can I source a new or remanufactured crankshaft?
What will change if I just bore my current crankshaft to 0.25 in terms of performance, etc?
While the engine is open, what are the options to improve my engine in terms of parts and specifications?
