thanks altezzaclub.
checked the vacuum lines n surely most of them have been totally messed up with,n i suspect the carb is just pouring in fuel,
best option is doing a whole engine swap.
carbonboy..i will check the lines once am onto the engine swap.
guys am also wondering if the 4agte will seamlessly attach to my t40 gearbox without any modifications, i don't mind the engine mounts modification coz the engine bay is quite big,
