I have enjoyed this thread as much as any I've read on this forum. Being a nitro-head, I'm still absorbing EVERYTHING I can regarding these beautiful two-stroke gifts from God. ;-)

Other than ''longevity'', what can one expect (examples) from an O.S. engine vs a VX assuming they have the same specs (displacement, stroke, output, etc.).

I have run only RTR engines, and I am extremely anxious to see what my O.S. .25xz offers compared to entire kits that cost the same amount. I realize fuel consumption vs powerband is subjective for what is desired, but I'm talking about flat out performance.

On thing I am certain of, there IS an extremely tangible difference in performance as I see some engines at my track that are a lot ''different'' (in a better way) than mine.

I'm not going to build my MBX6r until spring, but one thing is for sure....when it comes to engine performance, I will be all in. Regardless of anything, I want to ensure I have the best engine that can be mounted on a buggy. Be it a $150 engine or a $950 engine, this piece of hardware seems to be the great equalizer at the track.
