I'm planning to buy 350z and aps tt kit, I'm also planning to rebuild the block and new rods pistons ect, so I see acouple high milage 110-140k z's because they cost alot less, would be it better to get a 04 or the 06 with the revup engine to work on? or it uses the same parts and block and all?

 

it wont matter. it will be a new motor regardless.
