Anyone out there know if the J-spec intake manifold is worth puting on my 96-SE. If so how hard are they to install. Will I need a ECU upgrade. Im still kinda new at the whole mod thing. Any help would be great
i don't know much about the J-spec 4cyl. But the kl-ze2.5L you reach max horses and tourqe around 6200rpm. So I would guess it would be higher for the J- spec 4cyl. as well. Do what the Jackson racing did to the Focus. Put in bigger valves and a turbo, it from 130 horses to 300.
