Yes, there are street legal 906s.
I can't remember when Porsche decided to do this, but in 917s the frame was also the oil supply lines so they installed schrader valves to test tube/weld integrity.
Actually, I believe they pressurized the tube frame. If it lost pressure, it was cracked.
A little story with pictures for you.
Do a search on Dr Evil and 914 transmission. Mike is a 914 guy who has some pretty good DVDs on 901 transmission rebuilds.
Hello,
I am working on a similar project and was hoping to talk with you about your 906. Could you please call or email me, 858-472-4397 / sstyles@kfmb.com.
Thank you. Shawn
