    This should be able to fit in the Jato.






    Joking aside you can put a .12 - .20 size engine if you want a .21 or bigger you will have to a big block conversion kit. However, an O.S.21TM will fit because it is in a small block case.

    I use motorsavers air filter but it is many out there that are good.
    Speed is the rate of change of distance with time.

    the biggest i would go would be an os 21 but you can go bigger and jclay i think we can get that to fit might need to extend the chassis a little and put some heavier springs
    Jato os21tm,Slayer/revo lrp.28,yokomo gt4,jamminx2

    I would suggest taming the jato first....They scream a little more in real life than you may think !!

    Amen brother. This thing is brutal with good tuning, and just plain FAST with a safe, fat tune!

    First what engine engine do you have 2.5 or 3.3 if you have 2.5 try the 3.3 if you have a 3.3 and you tuned it right and your not happy then how much do you want to spend and how fast do you want to go sky is the limit .

    Max power at 40,000rpm.I like it but for a different vehicle like a mugen mrx4.One wreck in a jato and a cracked block = 500+bucks down the drain.A good find though I like it alot.

    A engine that novarossi makes is a .15 like the 2.5 but should outperform a 3.3 any day of the week, forget the exact name...look it up on amainhobbies. And the Picco 12 red dots are awsome mills(Mine required no modification minus the flywheel nut)
    R/C is expensive...

    I have shoved a LRP .28 truggy bump start motor in my old Jato using the New Era chassis/kit, Revo 38t spur and Axial 22t clutch bell. How fast it got up to speed was just ridiculous but I don't think it was too much faster (if any) than the 3.3. Not because I ran out of throttle as I could hardly go past half way but was rather due to aerodynamics of the Jato. At speed of anything above (even approaching) 65Mph jato wants to be more of a kite than a truck. It would always just peel the front wheels off the blacktop and then it would just launch into the air. I managed to do so much damage just from all those high speed tumbles. Also I think a heavier engine in the back did nothing to help the balance of the truck.

    I honestly do not recommend going too big of an engine in a Jato. Something like a OS 21TM, modded 3.3 (what I have now) or a OS 18TZ (bump start only) will do very nicely.
    BASH. BREAK. FIX. REPEAT. ALWAYS REPEAT.
