Salam guys, i have Proton Wira engine 4g15 SOHC. if i want to change SOHC to DOHC by changing top engine is it possible and worth it?

Hi bro.. question is why do you want to do this? It's easier to just change whole engine + wiring. 4G15 depending on which model doesn't have a easy head swap fitment. Is your 4G15 VDO or MMC?

Not worth it in term of performance, twincam doesnt means more power.

You know 4G15 DOHC, the cam pulley is the other way around right?
