hello,i have a toyota solara se 4cyl l wanna put another engine im thinking a dohc also is automatic l wanna change it to manual how much you think ima be spending a good calculation well thankz alot guyz!!

the setup you have can be made stacks quicker as it is, all yu gotta do is advance/retad the cam timing (spark timing is different) by popping the cam belt off turning the cam 1 tooth and popping it back ontill you get the power youre looking for and dont be scared of nitrous it works perfect in autos
