Don't know about DKP but I had two neighbors that ran Porsche power in their VW's. First one was a '58 or so sedan with 356 power (this was in the 60's) The other was a super clean black '67 Sunroof with 912 power (this was in the early 70's)
I always liked both cars
First quick bug I ever saw, silver oval w/356 motor and chrome porsche wheels. Belonged to a spoiled kid named Ricky, who terrorized the streets of Santa Ana, Ca. circa 1963.
The car didn't last long, he crashed it heavily, mangling his legs. Quick while it lasted, humbeling many a Chevy/Ford.
