This Maybe A Stupid Question

my buddy has a 91 sentra se he doesent have access to a computer so he asked he to find out what he can do with his stock 1.6 or if an engin swap would be a better choice if anyone has any help or knows where i should look to find what i need
thanks

You can always add an intake, headers,exhaust,ECU to a standard GA16DE but if you want more bang for the buck, nothing beats an SR20 engine swap

thanks for the help man
