The LRP .28 is a great budget engine that makes tons of power. I have about one gallon on mine and it still locks up at TDC without the glow plug in it just like an italian made engine will. Mine runs around 220-230 degrees all day long and I haven't had any issues with it at all.

To answer your piston and sleeve question, yes you will have to break in an engine again if you replace the piston and sleeve. It's also a good idea to check both front and rear bearings and to replace the connecting rod as well.
I've heard of these engines lasting well over 7 gallons if taken care of.

Here is a video of my LRP 28 in my LST on youtube:

It takes my wife about a minute or so before she realizes she can zoom out on the camera....lol.

Just a suggestion. Instead of getting a used motor get a solid and cheap new one. In a lot of cases a used engine will cause you problems.

I would look into a good .21 instead of the .28. Most of the fastest run .21's now because the .28 have to much power and drink the fuel.

With that being said, you CAN find great used engines. Just be selective.

Here are a few choices:

http://www.carolinasrc.com/Webstore/...idproduct=8802

http://www.carolinasrc.com/Webstore/...idproduct=3886

Here is a new .28

http://www.carolinasrc.com/Webstore/...idproduct=8838

A bit more than the .21's and HUGE amounts of power. To much IMO for a track. But it's a good one. The .21 I listed for you are good engines and will not be much more than a rebuild for a used engine.
