what do you guys think would be a better engine to bolt up to my revo i talked to 2 different hobby shops and one dude like the rb concepts and the other like the o.s. engines. id rather get an opinion from a bunch of people rather than just one guy. i heard good things about the o.s. engines but i have never ran wither of these engines.
 
You can do better than both with a OS .18TZ but its not quite a direct bolt on. The RB is a good strong motor. Maybe a little bit to much torque for the average joe to race with. But you CAN race with it. I raced and one with it. The OS TM is geared a bit more for racing. doesn't have nearly the torque of the RB and it has some pretty decent top end. I would prefer a ported ostz over both though.

but its not a elec start is it, i thought the tz is a pull start. whats the difference between the tz and the tm. i really dont race I'm more into just bashing around in this feild we have that has a few jumps no real racing on tracks here but i do screw around on them occassionally.
 
The RB is too much for racing. The TZ perf gains over the TM aren't enough to justify the time and money to make it work.
 
ok thats cool i dont race anyhow I'm just looking for an engine that has some torque to bash around in.
 
Might consider the Picco .26 instead of either of the others. it bolts right in with the picco engine mount for revo and nobody with an 18 even comes close to hangin with it. Besides its the best running non stalling reliable engine I've ever owned including the os 18 tz.

Wow you are 100% wrong on both accounts. The Os TZ is noticably (sp) faster than the TM and yes you can race with a RB.

You know what they say about opinions, your entitled to yours. I outran a TZ on track, some of the others around here with the BB will tell ya it's too much for the track. So I'm 100% wrong? KMA

ok let me clarify what I'm looking for. i dont race probably never will all I'm looking for is a engine that is good for bashing around in and climbing hills(rough terrain) i just want something with alot of torque but not something that will break my stock drive train. and something that will bolt up to my ez start equip, and stock engine mounts. everyone has there own opinion cause every person I've talked to so far has told me to get a differ mill then the other guy. i just figures i could get a bunch of differ opinions and maybe see what was working the best and the most reliable.
 
Not sure where Jackson is in CA but RevoRancher lives around the OC and has a BB, maybe he can help ya out. Suprised he hasn't stuck his head in here. Just bashin', you can get away with just about anything.

If you out ran a TZ with all things equal something is seriously wrong there. Yes I ran with a RB and won with it so like i said you are 100% wrong. And this is not a opionion its a fact. A tz is faster than a tm. a Rb can be used at the track if the person using it knows how to drive. period. This is not a debate.
 
Actually, I race with my RB 323, and I love it. I would prefer to race with a more de-tuned mill that makes all it's power at the top end like end the OS .18's, andthat is not slam, by the way, but for overall usefulness, the RB is incredible. LOTS of low end and crazy but tunable power. Plus, in the kit, it has all you need.

For racing I am now thinking my gearing combos. But for mostly bashing, stock is fine. I have yet to trash a diff, by the way.

All the motors have nice torque. The RB has by far all the torque you will ever need for anything. It comes with its own engine mount , header and pipe. You can use a traxxas pull start on it.

Diddo. I havent broken any drivetrain parts with the Tm or Rb. I do whoever run a FOC in the tranny.

Hey tool, read my original post. Never did I say you couldn't run a RB323 for racing. I've seen it and heard it from many people the motor is just too powerful for many of the smaller and tighter tracks. And on paper yes the TZ is rated for a slight horsepower advantage but again, I said for the time and money required to make it work it's not worth, especially now since he said he is not racing. That was an unknown at the time. The TZ is not a direct drop in, especially if you are using a POS easy start. Now are you calling me a liar for saying I outran a TZ on track. I outran one I ran against and lost to another because of fuel. I'd hardly call loosing to another Revo with a TZ by two laps in a 20 minute main much since I had to stop 3 times for fuel and he stopped once cause he was running a Spider tank.

:sigh:

ok Happy New Year Buddy.
 
jackson is up by sacramento so you think the rb is decent enough for just bashing around. thanks guys for your help on deciding which one to buy. you guys know alot poop, is there anyone up in the nor cal area that goes out racing i wouldnt mind checking some of the tracks out maybe trying them out.
 
FastEddy, Sweetdiesel and Robmob are somewhere up your way, but since I don't live there I couldn't tell ya how far the drive would be. I think they are more of the bay area though. The RB is a good motor don't get me wrong. The other thing to think of with it as far as racing would go (which also depends on the track) is more than likely you would be in an Unlimited MT class. Usually the "stock" classes are .18 under and no center dif, if the track tries to use ROAR or IFMAR like rules.
 
Check out the HP difference between the two, and decide...

http://www.nitrodynesystems.com/Engine Database.htm

These tests were done by an independent. Don't always believe the HP numbers from the magazines.

I bought my RB 323TM for only 100 bucks. Only had 3 tanks of gas thru it. I haven't installed it on my Revo yet as I'm waiting for other parts to come in so I can build myself and ultimate Race Revo. The track that I race at, doesn't care about the size of the engine...that's why we have an unlimited monster truck class.

You can't go wrong with either engine, but the RB definitely offers a lot of bang for the buck. It comes with the mounts, pipe, header...all for around $220. Not bad. Plus, it uses standard plugs. I don't know about you guys...but I hate buying turbo plugs. Too damn expensive, and the OS .18TZ is a turbo engine.
