Welcome to TampaRacing. Please ask a valid question so you can read through countless pages of bullshit, and never find one answer with any relevance to your original question.
You are all fucking retarded, and I hope you fucking choke on your own vomit in your sleep.
You should be more specific with your questions though. Worth is something that differs from person to person. The average person would say no, but the average person would probably not do any engine swaps in a car.
What are you trying to get out of the car? Rotaries are great engines, and have lots of potential, but like mentioned, can require more maintenence. Are you going for speed, handling, originality, workmanship showcase?
You will need custom motor mounts, and transmission mounts im sure. Custom driveshaft...yes but thats easy. You would probably need a standalone, wich can also cost money. Although I am sure a stock conversion harness can be made for a price.
If you are building a show car, or you are a shop trying to showcase your work, or you just really love rotaries. Then yes its probably worth it.
If you just want to skip the sr20 bandwagon, and live in moms apartment with no garage, or tools...then no, its probably not worth it.
