I just picked up my first tub from someone throwing it out. I have been looking on the forums now for some time now and decided to ask .Where to start? The shell is in great condition, but i know i will need a new spa pack. the plumbing looks ok, but want to add quite a few more jet. It is a jem spa, cant find much info on it just a tag that said it was installed in 1998. I am looking forward to taking on this project, but would like to know where I should start. I plan on working on this for the next few months to spread out the cost, but dont know if I should start with adding jets or the spa pac or adding manifolds to it and replacing plumbing.
Any help would be great
Thanks

post some photos of the spa and that'll provide a starting point.

here are a few pics

sorry they are so big
