This is the Novarossi 2.5 Super Charged Engine with included 51225-206 manifold & pipe set, and is intended for use with the Traxxas Revo Monster Truck.

This 2.5cc engine has been produced exclusively for the Traxxas T-maxx and Revo Monster trucks. The 2.5 Super Charged (N2.5SC/RT) features the famous build quality and out-standing performance that you expect from Novarossi. This engines performance comes from the perfect mix of competition parts, including a 3 port ABC sleeve and a Turbo SG type crankshaft with an M7x1 thread to match the clutch systems from Traxxas. Also, this engine comes complete with a Novarossi rotostart system installed, and also includes a Novarossi 51225-206 Revo Tuned pipe and manifold set. There is no need for a different engine mount either, just remove the Traxxas EZ-starting system and you are ready rip!

I purchased one of these for my Nitro Slash that has a Jato tranny installed (easy, easy mod btw). With the Novarossi and 2-speed the thing flies. The engine is good quality and starts very easily and holds a tune as well. Although I haven't had any issues so far, the rotostart seems flimsy and you can see the housing moving around as you're starting the engine, but time will tell how well it holds up.

Even if you are installing this in a regular Slash/Rustler with the stock tranny, the header and pipe works fine. The pipe is 1/2" or so farther away from the chassis, but I just used a longer pipe wire and it works great. Hard to find an engine/pipe combo for cheaper that will match the performance of this Novarossi.

I was a little doubtful this would be a direct replacement for the revo 3.3, I was wrong,I installed it in 10 minutes, everything fit perfect, and the performance is unbelievable.In my opinion it turned the revo from a toy to a beast! Typical novarossi performance,almost to much!

Well it says its a direct fit well its not it took some work to get everything to line up. The carberter linkage is not at all close to the 3.3 I had to use the 3.3 carbeurater arm because the one that comes with it is not long enough. I also had to raise up another part of wear the linkage hooks up to on the chassis. Well after some engineering and patience I got everything to move smoothly with the carberuter. Broke in the engine with no problems. I've ran almost a gallon of fuel in it by now and its really starting to scream its probally about as fast as the 3.3 but its way easier to keep it tuned. I usually just have to move the main jet screw a little bit due to weather and I clean leave it my 3.3 seemed like I was having to adjust it constinely also I have no problem keeping this engine around 200 to 220 degrees. My 3.3 seemed like it was either way to hot or to cold. Note if you dont have the tune just right on the novarossi it wont idle or hardley run once you get it tuned it will idle all day long and run perfect and the fuel lasts along time. I tell you what I will never by another 3.3 this is 100 times better. I would give this engine five stars if it would have bolted in and lined up perfect but i took quite a bit of work to get it in so I give it four stars.

Motor came with a bad roto start gear out of the box. A main is awesome they offered to give me a credit for the motor even though it's not their policy, I decided to try and take care of it with novarossi because nobody had this motor in stock anymore, I wasn't trying to spend more $ on another motor, Novarossi sent an email saying they won't support the motor because the factory failed that was making it. No support no nothing. Just an expensive paper weight from Italy and a company that I will never support.

Just to clarify I bought this motor and I wish I had just saved for another OS engine, or even another 2.5r would of been been better, anything that actually isn't just terrible from a terrible company(looking at you novarossi) now I've wasted money on this and will probably have to save for a new engine again as novarossi doesn't support their product or stand behind it.
