hi skywalker..4G67 has similiar mounting point to Vr4 (4G63 ) but a little different with 4G63 ( evo 1,2,3 ). 4G67 mounting point are totally different with saga (C12) chasis, cannot be plug n play, need to do a little modification on the cross member and mounting engine side.
From what i heard recently, JPJ will not approve engine registeration with over 20% from stock engine capacity except you have an 'internal cable' person. however,in last two weeks ago, my buddy from c12 club has declair his ride (saga+vr4 ) with cost Rm2.5k (without bring along his ride to puspakom). The registration are valid in the system...fuh crazy person
