As a teenage convene fan, we was of march really excited”, says a 57-year-old, who – with assistance from friends and experts – set about operative on his possess vehicles with good passion.

Step by step, both a strange and a reproduction were completed

This unrestrained for Porsche and a record finally led to him determining in 2014 to modify a 911 S from indication year 1970 into a 911 ST 2.3, regulating all of a special tools that a contemporary racing text “Sporttechnische Leitfaden für Porsche-Fahrer” from 1970 indicates for this vehicle.

The automobile also facilities special cylinder heads with incomparable channels and dual tiny hint plugs per explosion chamber, a Marelli twin-plug distributor, Carrera 6 camshafts and a form 46 IDA 3C Weber carburettor. While Knoll was in a center of converting a ST in 2015, he came opposite a remaining strange Repsol 911 ST 2.3. “Unfortunately, it had some engine damage, though after a consummate visible investigation with experts, we did not demur for a singular second and decided: now we have two!” recalls Knoll. For a consequence of newness he usually had to reinstate teenager things like a seats and a back fender on a former Spanish racing car. Step by step, both a strange and a reproduction were completed.
