bore out a motor?

[multidookey]

hey random thought came to my head and im getting ready to sell my 3.3 and do an electric conversion. but before i do is it at all possible to bore out one of these small engines? i know they do it in full scale because my friend bored out his diesel to a 6.2l and just if i could do that i would like to do it and test it out. let me know your thoughts thanks.

Short answer, No.


Where are you going to get the correct size OD piston after you enlarge the ID of the sleeve? Compression relies on a near perfect fit with a ring less piston.
Also, the sleeve is tapered and chromed. You would need to taper the ID and then re-chrome it and fit it with the correct size piston.

I believe you can have your 3.3 ported and polished I think I've read on here once by somebody. Is that right snook?

You can have any Nitro engine modified, port/polish, timing altered, crank epoxy, etc. Increasing the displacement by boring the sleeve like a 1:1 engine is not a feasible option.

anything could be done if you have the coin.. but as stated not a feasible option.

it would be alot more cost effective to just buy a bigger engine.
