[CAMBOS13]

i know this has already been established multiple times over and over again. but i have a s13 and i put at s14 KA into it will crank but when i go to get it any throttle it will die an just bog down. i know its in time, getting fuel,and spark do you ALWAYS HAVE TO CHANGE THE INTAKE MANIFOLDS ON THE KA's?



thanks in advance.
