thanks alizzz79 brother for extending your help 
presently i dont own any jimny but i m seriously considering to buy one at some reasonable price.
but before all this i just wanted to know the above issues of engine swap.
i have read your thread of pajero jr engine swap from 660 to 1100 cc i found it very much useful,
thanks once again.
may be somebody on pakwheels has experienced the same swap on jimny he will be the best person to guide us.:S
