Assume you are in Malaysia, 4G13P recomended upgrade is 1.6 SOHC (4G92P). JPJ will not allow you to jump 1.8cc. You can also consider 4G15P much more cheaper upgrade compare to 4G92P.
How to go about?
1.) Find a good mechanic
2.) let him know your budget
3.) Just pay and let him do everything (easier, unless u want to cut cost do the inspection yourself)
If you want hassle free and safe cost, 4G15P would be a wise choice. If you wish to upgrade abit for performance 1.6 is never wrong. Good luck and happy mod.
Hi LeBronJames,
Thanks for your reply and advises. I am from Singapore and my mech in Johor does recommend me to upgrade to 4G15 instead if I do not want too massive and messy job. He also mentioned that my original wirings and ECU remains and only need to replace the engine will do. And I guess should be a wiser choice also.
