seaaarch yo.SR20 has an A$$LOAD of aftermarket because everyoen and their mom does one-im not exactly sure about the RB20...but again search lolit depends on what your goals are, the RB is an cast iron block so it can handle much higher HP, but the SR is lighter and many claim it is pretty damn strong for aluminum-people have made over 400hp with it
everyone will tell you to use the search button and do some research-it helps alotgood luck man
