if u r worried abt reboring ur engine block.....
u can change it....
if u r thinkin dat its troublesome to do another inspection....
can ketuk back ur ori engine number....
wahahaha.....
its good to register if change engine block, puspakom will not cost u much.
if ur mech dunno how to ketuk, there is a chance ur car get 'sita' or consider as 'illegal modification'...if jpj found out during roadblock...
so y take risk....
