RE: upgrade to 3.3
Nothing. The 3.3 is a direct swap for the 2.5. Everything from the 2.5 bolts directly onto the 3.3. If you've got the tools to work on your truck/car then you have all that you need.

The Sirio .23 is a big block and is not a direct fit. Go with the 3.3 they are qauility engines, have plenty of power and will rev out of this world. You will be happy with it if you break it in right and tune correctly. There is to many guys that bash the 3.3 engine cause of engine failure, but it is usually due to the lack of tuning or maintenance on there part. The only other engine i would go with is the OS .18TZ.

RE: upgrade to 3.3
i just put in a .18 os tm in a 2.5 revo . it is a direct drop in and also can be easy started . ive bought both engines in the last 3 months and i do prefer the os . for me , here in wisconsin , its easyer to tune . the 3.3 here is a cold blooded beast. but the 3.3 is very fun in a old 2.5 rustler with a 24 tooth clutch and 68 t spur . just my 2 cents
