At the moment I have a 1991 corolla with a 4afe engine in it. I want to know if I should leave it untouched or search for a 4age to put in it. As it is its pushing 103 horses, with the research I have done the 4age would do about 140 horses and I want fast.
I was also wondering how hard it would be to swap an engine for someone with limited experienceđ.
