I have a Volcano SV made by Redcat Racing and from the factory it comes with a VX .18 engine. Its a decent running engine, Performs pretty good for the most part. I am interested in buying a new motor to put in this fun truck. I was just wondering if i would have to stick to a .18 engine or if i could go a little bigger than that without having to modify the chasis or body. Ive already figured out that i can use a back exhaust port so i dont think thats gonna be much of an issue. I was just kinda hoping somebody here has already done the same thing or had done alot of research. Im pretty new to the hobby so i have alot to learn and dont know exactly what to search for. Any help is greatly appreciated!

One last note: Ive been all over google all night and i cant find the specs for the VX .18 to compare to a potential upgrade. Anybody know where i might be able to find the right specs?
