About 246 pounds excluding the radiator.
The main problem with rotary conversions, as you may know, is the exhaust heat. Everything has to be kept well away from the exhaust tubing, and shielded as well. After that is resolved, the other problem is that most rotary conversions are unfortunately not very fast. Most people discover this too late. Even a stock 914 2.0 will leave this 13B-converted 914 in the dust every time, because the big difference in torque means a big difference in acceleration from the word Go, and that difference cannot be overcome on the road or track. And from that day forward the rotary conversion basically sits in the garage.
It's one of those "it seemed like a good idea at the time" things.
