They have multiple kits available. Also recommend you get their rebuild video first to study what you will be doing.
Also why are you rebuilding after 83k, did it get overheated?

The motor that I'm rebuilding yes it only has 83k miles on it but I figure if I put all new seal,etc. it'll run better and be more reliable in the future I dont know how much abuse the motor has seen in it's early days so if I Put everything new in it I will know my motor inside and out and can insure that it'll last and withstand my kind of driving for a long time, with propermaintence that is.

Most people only do rebuilds for a reason. If your motor only has 83k buy a bad motor to rebuild and sell yours. That way you have no down time and you can port and upgrade anything you you would like to upgrade.

While many people rebuild thier engines because it has failed and they need, there are some that go through them engine to simply freshen them up with new seals, in part for performance, in part to avoid more costly repairs down the road when an apex seal takes out a housing or a bad bearing takes out an e-shaft.

Go for it Nate.

The racing beat is the most complete kit I think. Atkins has a bigger kit that might be the next best thing. I think it goes for 900. The racing beat kit includes new bearings and everything.

Nate, until you pull down the engine, you won't know for sure what you need. With the mileage on your engine, the bearings, housing, irons and e-shaft should still be within service limits. The apex seals might be too, but I would replace them any while it's apart. That being said, the gasket and rotor kit from Atkins should be all you need. You should replace all of the springs, the oil control o-ring carriers should be within spec, side seals rarely need replaced, unless you break one and the used ones can be flipped over and reused if needed..

I would upgrade to the 3rd gen corner seal springs and solid corner seals, it improves compression and the solid ones are an Atkins exclusive. I have had very good service from them btw.

Before you tear the engine down, run Seafoam, atf, even water through the engine, This will remove much of the carbon and make parts cleaning, rotors in particular, much less work.
