Is there any way i can put a 3.3 engine on My 2.5 Revo???

should just drop right in

The 3.3 will drop right into your Revo, it's the same case deminsions. Only need the bigblock conversions if you are going to a .21-.32 motor.

Dont go 3.3 get a dynamite .19 its faster same price, better and last longer. Best part is its made specificaly for traxxas models to drop right in.

get an os 18tm if you are using the ez start, get an os 18 tz if you are using a starter box. best motors and easy to tune. When I had one i bought a chassis for a 3.3 and switched it over to the longer wheel base and it made a huge difference. all you need is a chassis, body and a longer driveshaft. And a lot of time LOL. If you are racing it will be night and day.
