sluggish with AC switched ,,,,,,,,,,,,thats a common problem and cant be overcome ,,,,,,,,,your car is equiped with ND piston compressor which puts some extra load then rotary and reciprocating compressor ,,,,the good thing is that its capable of keeping the cabin cool,..........but the real test will be in extreme hot temperature,,,,,,,,,,,,,,well about the condencer,,,,,,,,,,,,,,,,yesterday i visited some shops and discuss that with some mechanics as well,,,,,,,,,,,,,they say the old ND condencer works even batter than multi flow ,,,,,,,,,,,,,,,some says both have same performance,,,,,,,,,,,,,and none of they say that old single flow is not good in cooling,,,,,,,,,,,,,,but the fact is that the milti flow has batter efficiency,,,,,,,,,
you have to alter the condencer outlet pipe which goes into the evaporator,,,,,,,,,,,,,its dryer is also difrerent connections ,,,,,,,,,,,,,,need some pipes to weld but its not a big deal,,,,,,,,,just one weld of 50 Rs,,,,,,,,,,,,
