everyone knows the heater/ac in the s30's is far from great! has anyone ever used a complete system from a newer model car and retro fitted it into an s30. and by complete i'm talking everything from plumbing, to fans and the hvac controls themselves. i was thinking about trying one from more modern car in a similar size but i dont want to waste alot of money on something that wont work. not looking for anything fancy as far as the hvac controls go but something from late 90's early 2000's w/ to have defrost, vent, floor, vent+floor, and defrost+floor...
any ideas? i was thinking maybe a miata or something
