check this out i swapped b20vtec into my ej1 and b series dizzy was bad. so i took the d series internals and swapped them into the b series casing. now my car seems to lose power with b series ecu, but pulls great with stock p28.
are the internals different or the same. and this is no joke the p28 will run the crvtec way better and smoother than the gsr i dont know why! so help is great.
