Since you have a manual, focus on EOC and less on engine mods. You're doing more idling than anything so start coasting a bump staring. Making better torque is nice but weight reduction is free if you can stand to lose carpet, useless back seats and other panels. Get a light weight battery or switch to those fancy super capacitors. You're rack and pinion right? Delete the PS pump and loop the lines. What kind of smog pump do you have? Can you delete it and stay DOT legal?
