Which kit will fit in 01 Honda Accord

[Gordy]

I am interested in installing one of Bob Volks HHO kit into my 01 Honda Accord 2.3l
I was wondering if anyone has installed one in a similar accord and to see which worked well.
when i open the hood, I cant see any open spot to install it, so if anyone has suggestions it would be appreciated.
I also need clarification on O2 sensor standoffs, can we us this instead of the EFIE module, my car has two O2 sensors.
I am leaning towards getting the big box kit, so i wonder if that generator will fit in my car.

thanks
