so I have a ek9 rally car and I’m looking for a bit more power. As this is a rally car I need to keep it as a 1600 and can’t turbo it. It currently has a standard B16b engine with whales induction and 2.5” stainless de-cat exhaust and close ratio gear box. What do people think to changing cams? Is a larger throttle body and intake manifold better than throttle bodies. What about exhaust manifold? Car had Hondata fitted so can be tuned to get the best out of any modifications.
