You can interchange the sleeves between the Pro engines in .21 class.
you cannot interchange them between Pro and Sport class engines.
you cannot change between Sport .25 and .28 and Pro .25 and .28 .. Crank case changes will hamper the gas flow between the RTR crank case and Pro crank case .. So it wont really give you the max change .
Hampering the gas flow can cause over heating problems.
Re Special RC, Please be aware that the Go Factory does not modify the engines , they are stock gen 4 and 5 engines. Note he does not have gen 5.5
which are being distributed to Authorised dealers only. He is stating that they are modified so he can sell into other peoples areas. but be aware that you do not get any warranty with the engine from Ebay . only an Authorised dealer can factory warrant an engine.

When rebuilding the motor I take it apart and clean it, inspect bearings, inspect crank and rod for wear (i use a mic and a bore guage that measures to .0001 of an inch), and pinch the sleeve. It includes replacing rod or bearings but any parts are extra. I usually use Tko ceramic bearings, the rear is $22.95. Of course when I'm done I put it back together.
If I am just pinching the sleeve I will clean the top of the piston, I don't recommend a dremel and wire wheel!
I am going on vacation and won't be back until 1st of May so I won't be doing anything for 2 weeks.
