question about engine setup
ok say we have a b18a with ported tb, ported intake mani, and ported head...would it be a good idea to upgrade the fuel rail and add a fuel pressure regulator with upgraded injectors? ...
stock fuel rails are good for 400whp. a fpr is also not needed unless you have a bigger pump. injector size is determined by whp levels. stock injectors can handle 180-190whp.
