vr4 200 is the first batch if not mistaken , and the vr4 220 is the second batch with different ecus , the 200 has an 8618 ecu and the second batch i donno whats the code but the ecu is thinner and its on different wirings . the vr4 200 automatic comes with a TDO4 twin fin as the manual comes with the TDO5 .. so the vr4 200 & 220 difference is the ecu & wirings , others are all the same ..
the vr4 240 is the rs version , which has bigger turbo tdo5 16g , bigger injector 510cc , bigger intercooler , different ecu & wirings , twin pot front disc brakes , the head cover which has a daimon star " mitsubishi logo " where else the other version does not have .. and i notice some vr4 rs comes with the ECI throttle body & some comes with the ECI MULTI Turbo Intercooler throttle body ..
