I am looking for a bolt in motor that can replace the 3.3 and give me more power. I would like to retain the EZ start, and stock mount. I have a 3.3 with trinity pipe looking for more power but not out of controll.

Thanks,

JC

Which O.S. motor? The .18TM? The 3.3 is a .21. Why would you want a .18 over a .21? Are you bashing or are you raceing? I race with a Picco .26 but you must get the truck set up right and you must learn how to drive it.

O.S. 18 TM

F-150man94

muddymoose92, do you even know anything about either motor, or are you simply writing an answer just to be writing?
I have both motors. I run both motors. I hate to say it but the Picco .26 will destroy the O.S. TM in a race. I do it all the time. I also beat up on BBs every race. Here is proof. You can't argue with results!

The 18 tm will beat a 3.3 engine aslong as the trucks are set up the same (same ratio tranny, gearing, weight) all that stuff, the 18 tm will have more torque and more top end, but it wont compare to a picco .26 in power but it will in reliability.

The 18tm is a great, great engine..tunes easy, durable, plenty of power, etc. You also get OS customer service which is the best. That being said, the picco max 26 is stronger, faster, and has quite a bit more power. The mount for the picco is JUNK however...it takes more fiddling to get the mesh right with the picco and some people have air filter clearance issues...also, the carb on the picco is not near as smooth as the os..if you want the faster engine, the choice is obvious (Picco). If you want an engine that will run all day, be idiot proof to tune, keep a tune, not run for a month and then fire right up, etc...the os is hard to beat...just depends on what you want

How in the world do you know? You don't even have a Revo. I'll bet money that you don't even have first hand expierence with either motor. The Picco is as reliable as the O.S. I have both of them and they are both great motors, but the TM isn't even in the same ballpark as the Picco.

Kawasakirider

gtsum, I do agree the picco is a stronger engine, but lets give credit where credit is due, the 18 tm for such a small engine makes an INSANE amount of power, it has more torque than the 3.3 and a higher top end with a smoother powerband, it is an overall better engine than the 3.3 IMO.

Kawasakirider

HMMMM before you go making F$%#wit assumptions you could have asked, I have 3 friends with revos, one with an 18 tm, one with an 18 tz and one with a picco .26 max, I bash with them allot and I know which engine is more reliable I have driven each truck AND tuned each one on numerous occasions, get off your high horse, I NEVER said the TM had anywhere near as much power as the picco, can you quote me saying that? NO, all I said was, for a begginer, an 18 tm has more power than a 3.3, is EASY to tune, easier than a picco (not saying a picco is fiddly but allot of newbs do) and is ALLOT more reliable than a picco .26. My friend with a picco .26 max has been through 3 of them. Get your facts right before you go flaming people.

Kawasakirider

See, you even quote me saying the OS wont compare to the piccos power but it will in reliability, I never said the picco was unreliable, I just said the OS was a reliable engine more so than the picco (an experience tuner can make a picco last as long and tune as easy as an OS but a newb probably cant), so you have NO grounds whatsoever to start flaming me. Do you still want to make that bet?

gtsum

I am confused...I said "the os is a great, great engine" If that is not giving credit, I do not know what is? I have had 2 18tm's and installed, tuned, and ran 2 Picco max 26's. Bottom line (IMO) is the picco is faster and stronger, but the os18tm is the "perfect motor" for the revo..it has all the power most people would want, runs all day, tunes easy, good temps, reliable, etc. I myself have run about 10 engines in my revo the past year, with the last 5 of them being big blocks...if I was to to do it all over again, I would get an 18tm and be happy bashing and running all day (my lst2 being a natural BB truck is so much better with a BB in it then my revo is with a BB in it...due to balance, weight, etc, etc)

I agree 100% that the 18tm is a far better engine then the 3.3 also....not even close

Kawasakirider

There we go, from a person who has had allot of motors, he said the 18 tm is the revo's perfect motor. So to the original question I stand by my original answer which was the 18 tm, it has great power and is not out of control like many BB's are in a revo. I wasn't disputing the power or reliability the picco .26 has, I just said that the os is more reliable but has less power, that doesn't mean the picco is unreliable, it just means the OS is super reliable.

Hey my thread is getting hijacked...... I just want a good solid motor with more power and reliability. This seems to be the same debate that I am always exposed to..... DA-150 or a 3W-150.. you can argue all night, I am just looking for peoples experences good and bad and any recomendations.

Thanks

JC

Yo fastford, I'm sorry to hijack your thread, the os motor is great, as is the picco but your certainly aren't limited to those two. Any questions just PM me or anyone else, we'll be glad to help you out.

Hmmmmmm, key words here seems to be "bolt in."

The OS 18TM will bolt in and even make reasonable use of the OEM pipe and air cleaner, reasonable not necessarily being optimal. The Trinity pipe is an excellent addition.

The Picco 26Max will require a special mount to install. Wile it can be run with OEM filter and pipe it is far from it's potential, it benefits greatly from a different pipe and air cleaner. The Trinity pipe, like the OEM, does NOT have a large enough chamber volume to maximize exhaust tuning for this engine.

Either engine will give more power, but between the 2, only the OS18TM will bolt to the stock mount.
Either engine will make use of the EZ start.

For some people the Picco is "over the top," horsepower wise, while the OS TM is a real ***** cat, and easy to control.

Man, you climbed up on a high horse and started bashing people and you don't even have the correct info.
The 3.3 is a .20 engine, not a .21
3.3 cubic centimeter = 0.201 378 355 cubic inch
Also, simply stating engine displacement is NOT necessarly an indication of the performance it will produce.

Fastford,
Listen to beelzibub, he's giving you good, straight info.

F-150man94

Sorry about the .21 and .20. And yes I know the bigger displacement doesn't mean more power but in theis case it does.

I will climb back on the horse since he threw me once again.

Bwaaaahhaaaaaaaa...... darn stirrups! I don't ride nothing anymore that is bigger than me and can THINK for itself.....gimme a motorcycle any day! Horse meat is quite tasty...

My 2 cents, not that I'm an expert... I am in your same situation fastford. I have the stock 2.5 still, and will look into getting an upgrade in the near future. From everything I've heard from all the dirt track racers at my local dirt track, most, if not all of them run an O.S. 18TM. There are a few variances of opinions as with all racers, but for the most part, coming from the people who get their hands dirty, they swear by the O.S. but like I said, I have not had a Picco .26 or an O.S. I am just relaying the reseach that I have done myself cuz im in the same boat. The 18TM is an upgrade in displacement from my motor, but it is smaller that your motor, so I can see why you're concerned about going smaller but, from what I understand, the 18TM power to size ratio is definitely worth the investment when paired with its reliability.

My picco is an animal. Sick fast, but a pain in the balls.

Disclaimer: I'm used to tuning .90 size pumped heli engines that rarely need to have the needles messed with so I could just not be used to car motors.
