Hi,
it would depend on what engine, I run factory tuned engines where the piston and sleeve are not available as a seperate item so I would change when I feel there is a power loss or any wear on the piston etc, if I were to run a non tuned engine I would just look at changing every year the piston,sleeve,rod and bearings and any orings around the carb and or back plate but the same again only if I notice a reduction in power.
cheers

So you only change the engine when you can’t get the best performance from it or even after you have done a rebuild.
Please can more of you guy's, make some comment of your experience?

Motors can run forever but can't run forever and produce 100% power so to stay competitive i would change it after a season. If you can change piston, sleeve, rod etc for a fraction of the cost of the motor then i would do that. If it's to expensive then yeah go a whole new motor.

I haven't changed the motor in one of my cars for at least a year and it's still pretty good. (It all comes down to how well you brake it in i think) But it's not as fast as some of the NEWER motors out there though

so you think its better to buy a new engine say a nova 353 for approx $499 than replace the piston sleeve etc for under $200?? if you got the $$$ this shouldnt be a problem I guess.

ya i agree...
if rebuild going to cost you about 50% or more of a new engine price, then don't bother rebuilding.

As some have posted, it's a judgement call based on cost to rebuild vs price on a new motor. I personally have had motors which have been great and rather than buy a new one I rebuild or have the sleeve pinched. I have a Ninja .12 that I just had modded and pinched and it's almost as fast as my Evo 4 STI. It's definately faster than when it was brand new so it was worth the cost for me to have it modded and pinched. On the other hand I had a couple of WASP's that were crap and rather that rebuild I chose to go with a different manufacturer altogether. So if the motor in question has worked well for you I would say keep it and rebuild it or have it pinched and modded. You might be surprised.
