finally youre understanding my son. jk. anyway so the b16b is such an awesome engine. sometimes faster doesnt necessarily mean better. i mean if you take your cars to a show or a hangout everyone will be around your car because his is just another b16a swap. you would have a very rare and sought after engine. thats so tight that you can do that man. i would do it in a heartbeat. and i still think you could smoke him. it would be a very good race. get some practice in on your starts and smoke him!!! i mean i would rather have a b16b than a b18c turbocharged but thats my opinion. its not faster but will earn me a lot more respect from the auto community. good luck and hope you make the right choice. by the way a b16b would rip through an autocross course like a beast!! do it!!!
