Aditya, most engines can take more revs than they are factory limited to. The esteem like many other street engines are mildly stressed and going a couple of hundred revs over stock does not bring about any disastorous effects. Just as a reference, my stock esteem engine has done 3 rallies, 2 drags, and 1.5 years of engine abuse like tests at RPMs as high as 9000, ignition timing as crazy as 50 BTDC,40 ATDC, 110 BTDC, total hydrualic lock with fuel, etc all trying to obsere effects if something does go wrong...even today it works like a dream, and holds 185 psi compression .....
Forged internals are required only when you get to a point where stock is insufficient for your mods and needs..
As regards the maintaining rev limit with stock specs, incidentally on the test swift gearshifts were done at RPMs not exceeding 6700 -thats like stock- and the car was quicker. It all comes down to the engine, intake and exhaust systems.. Aftermarket ECUs increase performance by achieving optimal air-fuel ratios and ignition timing to achieve max power, they not increase airflow for a given engine,
You dont necessarily need high octane fuel on your stock or close-to-it esteem.
