Nishad, you would increase rod length by getting new ones made. To use the same block, you just get new pistons made with reduced compression height. You could extract a further mm or 2 by using smaller gudgeon pins - TRD has some lovely 20mm ones rather than the usual 22mm. You would use a crankshaft of standard dimension.
The main reason why one might use longer rods is to increase the rpm at which critical average piston speed is reached (roughly 4000ft/sec). The other effect is that it will increase the dwell time of the piston at TDC - this gives the burning charge more time to act on the piston.
With regard to getting a custom crank made, it is possible, but it will certainly set you back a pretty penny. If this is for a 2JZ, then I think you're probably wasting your time (money) getting it done - the standard crank is quite robust. As an example the JUN stroker kit for the 2JZGTE is about $14000 AUD.
