Some good ideas there, thing is i don't want to hack the original car to peices, so if i can i want to maybe run it seperate to the normal heater system?? Just stick it on.permanently cold then have a swith to turn it on, but i dont know if i can simply block pipes off or whether it "needs" the nissan heater box, and Retro Al, i do agree, power steering is for girls, haha, but i dont like being cooked in my car on a drive, so pants to it, im having aircon, hahaha.
