This is NOT a renegade conversion. But it is Rod Simpson's original Porschev conversion done at home in the driveway, probably before some of you were born
.
Simpson was the originator of the commercially available kit to plug a chevy into a 911 or 914.
He sold lots of kits over the years until his hard crash in a porschev at willow springs on a cobra club weekend. That put him in the hospital and he has not recovered fully from that. I am sure he would have refined his kit as technology improved.
As it is this swb 911 has indeed suffered this unusual "upgrade" that many don't find too appealing (then and now)
Renegade has done a lot of work in making these types of conversions work in terms of aesthetics, performance, and reliability
