hi guys. im thinking of changing my 6a12 na to either one of these engine. would like to ask for advice from anyone, what is the difference between rvr and evo 3 engine? apart of a detuned ecu, top mount intercooler and smaller turbine. all i know know is that is both are using 4G63 blocks. is there any other difference?
also, how reliable is the 6a12tt engine? i mean, i heard that maintenance is quite costly, compare to a 4G63. has anyone convert to a single turbo or change to a bigger...
