Traxxas TRX 3.3 Rear Exhaust IPS Shaft Standard Plug, Slide Carb Engine (Pull Start)
About this part
The TRX 3.3 Racing Engine™ draws from a legacy of precision Traxxas engine design and manufacturing. Traxxas has always been at the forefront of innovation, beginning with the powerful and reliable TRX Pro.15. Next, the Traxxas EZ-Start™ system ushered in a new era of convenience and ease of use with true, push-button electric starting. EZ-Start later evolved to incorporate built-in diagnostic functions, LED indicators, a constant-voltage glow plug circuit, and more powerful starter motors. Then came the TRX 2.5, a marvel of award-winning power and technology that sent the bar for Ready-To-Race® performance to unimaginable new heights.
Fast forward to the present and 14 years of nitro engine development have culminated into the most powerful TRX engine ever made, the new TRX 3.3 Racing Engine. It embodies everything we’ve learned from over a decade of making engines more powerful, more reliable, and easier to use. The TRX 3.3 Racing Engine is so powerful it establishes a whole new classification of power…. Extreme Power!
The TRX 3.3 produces an extreme 60% more peak horsepower compared to the TRX 2.5! The overall power under the curve is nearly 50% greater to deliver the smooth, linear power output TRX engines are famous for. The TRX 3.3 Racing Engine offers thoroughbred race engine performance that’s absolutely second to none. There’s no penalty to pay for having more power either. The TRX 3.3 Racing Engine is equipped with EZ-Start push-button electric starting and simple, reliable tuning from the two-needle composite slide carburetor. Plus it’s backed by the support and reliability you expect from Traxxas including the Exclusive Lifetime Engine Replacement Plan.
The TRX 3.3 Racing Engine is truly the pinnacle of power and reliability and represents the commitment to total performance Traxxas carries to the customer!

Decent power. Easy tune added it to my tmaxx 2.5R. Power ,I babies mine thru a slow break in and drove it 75% thru rest quart now 4 gallery no later still wheeling .i believe most just in a hurry to bash
This is a great engine .The break in was a breeze. Its very hard to tune though I had a rb .23 on my T maxx before this . and the tuning is way different instead of finding a great tune like hour s on a clock I had to do it by like min. maybe like 1/32 turn at the high speed needle at a time . If not you will be fighting the tune tell the cows come home. After 2 days of tuning and a 1/4 of a gallon later I have a great tune and I very pleased. If anything its got more power off the line then my .23 ever did.... I order this along with 2 gallons of nitro and a clutch bell and it all got here all atone time 7 days after ordering thats one week sooner then my lhs could have got it ordered for me at half the price.
If a 3.3 did not last past 2 gallons then it was probably run lean alot,or not taken care of,i have had mine for 3.5 gallons now and it is still strong,great motor for nitro rusty,polish the ports and get an ercm pipe to get the most out of them,do not try to fang port this motor,it will hurt bottom end,runs great ,idles all day!
Easy to tune, take apart, rebuild and run. A powerhouse of a small block nitro engine. Whats not to love?
Excellent Motor, the pull start is a bit rough on the hands. I attached to the T handle pull start a nylon 1/4 inch cord to a 1 inch metal tube with a closed loop. This made starting the motor pain free.
Reviewers generally rate the Traxxas TRX 3.3 Rear Exhaust IPS engine highly, praising its power, ease of break-in and strong performance in Traxxas T-Maxx-class models. Opinions differ on tuning: one reviewer found it fiddly, requiring very small needle adjustments, while others found it easy. Durability is mixed. One reviewer's engine failed before two gallons, which they suspected was a fluke, while another reported over 3.5 gallons and attributed early failures to running lean or poor maintenance. Some suggest porting and an aftermarket pipe for more output, cautioning against aggressive porting. The pull start is described as harsh on the hands, and a cord and handle modification was suggested to ease starting. All reviews reference the same variant.
