Hey i'm looking forward to buying a new engine in about a year (plenty of time to save) and i was wondering what the best .21 engine out there thats not to bad on money. i wanna get a .21 in my HP RS4 MT2 .. i've seen people suggesting the picco but i'm kinda looking towards the Nova Rossi...whatcha think guyz? and what will i have to change to get that big b**** in there? [8D]

The new Fantom .27s are AWESOME for the price; stronger than the wasp/picco and not un-Godly expensive like the Sirios...

The MT2 is a 1/10 small block truck so you can't just drop in a big block without modifying the drivetrain. My 1/10 4WD ST is able to fit a non-pullstart big block but I don't think my drivetrain can handle that power. If you going to do an engine swap, then I'd suggest hardend steel diffs, metal or thick nylon spur gears, and also if you can, get some thicker dogbones. But are you shure a big block can fit without chassis mods?

i dunno thats why i'm asking about this.

Yeah a .21 will fit. It'll be a bit tight, but it'll fit. Do a websearch for Wolfpack radicals, they sell a .21 conversion kit, a wise investment. About the drivetrain: after the first few "wot" pulls you'll need new diff outdrives and probably new dogbones. Maybe even a few gears. I know I did Hehehe...Ok back on subject.

Also look into RRP gears, they make metals ones to fit. Also you'll need to do a major upgrade on your diffs to handle the torque. I just dropped in new kanai diffs with the Hpi gear. it takes a little work but can be done. Another view point is to just buy a monster truck and convert it to a stadium (ie rear wheel drive)... Of course if your like me than the money pit is a good place to be. Be warned though, your truck is not meant to handle that type of power, and when you go out to play, stuff will break "EVERY TIME YOU GO OUT"... That being untll your whole truck is metal.

Now that your warned, go have fun!! I do
