I want to put a b20 to my acura integra ls. If i just put the b20 into my ls which has dc headers 4-2-1, short ram intake, greddy catback exhaust,how much more hp will i gain and how much more torque?

 

So you want to take a head thats from a 2.0 liter block and put it on ur 1.8 ls block and still see more torque increase?? you would prolly see more power just swapping the B20 into ur integra and doin a gsr head later on and basic bolt ons.
