power steering and ac actually take quite a bit of valuable horsepower away. it doesn't matter if you are using your ac, it still has to spin the belt and you still have the weight of the ac stuff. and power steering there is just no need for. but if you want it you'll still be ok, just get a little extra power without it. the h22a1 is out of the 93-96 prelude vtec. The h22a4 is out of the 97up prelude. the second of the two will cost you a lot more to get a hold of. you use the axles that go with the car the motor comes from i think. You might need a aftermarket one, i'm not sure.
