gday guys
ive been doing some reading and i think ive figured out that a ef bbm manifold on a ea will give better low end torque, is this right?
just wondering how much work it is to get all working
ill need the ef tb as well and cable?
is there anything else ill need
im thinking of the 4480 extractors too these will help wont they

i have a manual ea 3.9 mpi

any help will be good, thanks
