    Traxxas. They do the job just fine.
    You can get them modified or buy a modified engine.

    i was just wondering because i have been around the powersports industry for quite awhile and i know that there are many aftermarket pistons and sleeves so i wasnt sure if it was the same in the nitro rc industry

    No. I wish somebody would make aftermarket pistons and sleeves that are cheaper than the TRX ones.

    $66 for the P/S + $25 con rod for the 3.3 is just nuts.

    There are a couple, are they worth it? IMHO there are no gains, unless you have one that's ported. But with that, I wouldn't get them seperate, I would want to have the engine fully modded. Crank, Head, Piston, Ports, Bearings.

    Then when you add up all that cost you can get an RB 523TM and blow away any 3.3 stock or modd'd....

    I guarantee you a 3.3 will blow away that Rb523. And you don't have a Traxxas engine anymore just a crankcase.

    I've seen plenty of RB modified 3.3's. The OS's seem to come out much nicer IMHO.

    But I will completely disagree with you that the modded .20 ci is going to blow away an RB Concepts TM523 with 7+2 intake ports and 3 exhaust ports and the .23 ci displacement, a very well setup motor and you know it for a fact.

    If someone is blowing away a TM523 with a 3.3 than the owner of the RB milled RC should have it taken away from himself cause he can't drive or tune or both.......

    I always said you were one of the better engine modders out there. But let's be realistic here.

    At $145 I would get a Dynamite .21. I love my dynamite motor, and I know several people that run them and have had really good luck with them.

    You can always stick a TZ18 piston and sleeve and rod in a 3.3. You have to rebush the rod. They say the 3.3 is a 20 size engine but actually it is about a 23.
