Power upgrades for 04 Echo Hatch RS

[white_rice]

Hey guys.. a good friend and co-worker of mine just purchased an 04 Echo RS Hatchback. Its in really good shape and has already been slightly modded. Had a Borla dual tip centre exit exhaust, AEM cold air intake, TRD front strut brace, 17" MSR? black wheels, Eibach lowering springs, OBX aluminum racing pedals, aftermarket steering wheel, 10" Kicker sub in carpeted box, Eclipse speakers in rear, etc.. Might actually have been a previous owner of the forum here? It's blue in colour.

Anyways he isn't the most computer savvy and asked if I could ask a couple of questions. He would like to add power side mirrors to the car and also power windows and locks as it doesn't have any of the above. Are all of these mods do-able at a reasonable price? Is there somewhere that sells any of these kits or parts at a reasonable cost, and how-to guides anywhere? Any help would be appreciated. He is very mechanically inclined but just needs to know where to source out everything.

Thanks! :)
