apr it is completely up to you what you do,but just one thing I'd like you to keep in mind. If it's a 2003 model engine then it is now 14 years old and those engines only have an aluminum sleeve in them.So how much longer will you get out of it.I just recently had a Quantum the same age that had been serviced most of it's life and I took very good care of but it just wore out and the aluminum sleeve just wore down to far,it just wasn't worth fixing it.
So just keep that in mind.I'd hate to hear you went to the trouble of re-basing it to just have the engine wear out on you.
