I am not saying that I am going to do this, but out of morbid curiosity, what would it take to build an AWD 4-door Integra B-series? Has anyone every done an AWD 4-Door?

 

$$$$$$$$$$$$$$$$, I've seen videos of RWD/AWD conversions before, it's definitely possible, especially on a Honda.

 

Nothing different about a 4dr in terms of what you're thinking there's been a few awd builds all of them looked sloppy. It's not as hard as you think if you don't mind cutting holes etc, what is hard is the fact so many ppl cheap out. Guess what the most expensive things should be?? a good MIG and TIG welder you'd need to be a good welder too no using flux core/MIG(shielded) on everything. At least a 2 bay garage and plenty of good tools always saddens me to see so many builds under supplied, I went and bought all sorts of tools to accommodate my builds. Flood lights, TIG/MIG, jacks for my trucks to lowered imports... you get the idea


cost would be around the same as a k swapped car if you're just doing it for fun and not bling,
