I am having a eg hatchback with b16a2 engine with a gsr LSD tranny.and I want it to get the torque like the b18c1,but also I like to get a great gas millage.(I want to know which engine is more save gas,cuz I use for daily drive)should I keep it b16a and mod the torque like b18 like intake header?or should I change the block to b18c1 with b16a2 head?I am very confuse with this.or should I sell the b16a2 and get a b18c1 swap?and if keeping the car,which way mod can be cheaper to make the torque better.please give me some suggestion and tell me what I need to mod.thanks everyone
