Now if you are talking Ready Modofied motors like Rody's and JP's what you are getting is a motor in general terms, Modified timing alteration to the designers spec, . this means they give you a different sleeve and crank and in some cases ceramics.. Thats it.. And these motors can be improved upon definitely ! Ready Modified engines dont take it to the limit as the manufacturer understands that to take an engine to the limit may lessen its life if in the hands of an inexperienced tuner.. Someone who wants to go further will learn how to care for the motor by having gone through the experience..
When you map an engines port timings you can gauge where it needs improvement , sometimes all it takes is a little adjustment to help it along and in some cases a lot of adjustment as is the case with say a Force 25.. these motors go ok stock, but you can mod them to be comparable to engines that cost twice as much..

I hope this answers your question and as far as the piccys on the site they are part of a montage for astetic my web guy put on . The actual motors i sell are in the CMB Motori section ..

Hope this helps !

Cheers
