I found that thread no would all the parts be the same except for the air filters seeing how mine is 3 cylindersi know the jetting has to change and you need to use different cv springs. the oil tank and crank case vents need to be plumbed into the end of the filters to reduce oil burning issues. did it to brothers rx war mod over 10 years ago without plumbing in the vents and it did increase his oil consumption. most of the jetting and cv spring info will be with the ecp/k&n filter install in the rx1 section.
