Does anyone know if a 2.5 sleeve will fit in a 3.3 engine

no it won't its alot smaller.
.15(2.5)-.20(3.3) same block just different internals.

i had the same question too
i asked my local dealer and he said that it would fit perfectly

thats what i thought. I think i am going to put a 3.3 sleve and piston in my 2.5 case w/ 2.5 crank

oh well i thought the bores were different well tell me how that goes man.

the bore is determained by the inside diameter of the sleeve. But the outside diameter is the part that will decide whether or not it fits into the crank case. My theory is that a 2.5 crank w/ a 3.3 sleeve and piston will give me more top end horsepower (created by bigger bore) without uncontrolable low end torque ( created by longer stroke of 3.3 crank). This would mean a very drivable rusty w/ blistering top end speeds.

well the externals are the same except for the cooling head its just the internals are different also if you look at the traxxas revo review on the traxxas message boards the sleeves look to be a different size.

It cant be because the crank case has a diffferent hole for the sleves. They are completely different motors. It might work tho if you can machine it out.

thanx for the feedback this will be an ongoing project i will start a new thread when i figure out the answer

evader,

the sleeve/piston, rod, and crank will not fit the 2.5

have a look at this pic
