I'm so curious about my engine performance and really not satisfied..
Current using 4g91 DOHC and the performance for pickup very worse than previous proton engine.. Fuel consumption oso not so good..
If im using the original 4g91 manual gearbox its quite lost of power..
Now I'm using rojak gearbox 1.3//1.6 and its increase a bit for the pickup n torque.. no major modd.. using metal head gasket/ 1.8 na tb/ 1.8 cam pulley + adj pulley and fuel regulator..
So i need opinion from all sifu's to convert DOHC to SOHC coz on my thinking SOCH is really good than DOHC performance..
