In November 2014 I bought my F 355 with 512 TR engine conversion. It has the Fghnr. ZFFXR41B000108671 and was delivered on 6.5.1997 at Zender. Color: Rosso, upholstery: nero Equipment: ABS, El. window lifter, El. immobilizer, light metal rims, checkbook maintained, power steering, central locking, anti-lock system, sports suspension, immobilizer, power steering despite 512TR motor, central locking, no air conditioning! Complete conversion with 12 cylinder Testarossa 512TR motor and 5 Ga ng 512TR transmission at 55,182 Km stand from the company Dirk Küster Fahrzeugtechnik Düsseldorf, rear axle and braking system, adapted, control units and electronics adapted, modification cable harness and cockpit, sports exhaust system modified, everything entered in the papers!!! Service – and board folder original and complete! German vehicle with delivery at Maranello Motors GmbH in Cologne. A true masterpiece that only exists once in the world!” On 3.7.1998 was at 10,723km the 10,000km inspection at Maranello Motors in Cologne. Already on 15.9.1998 at 31.028km was the 30,000km inspection at Becker in Düsseldorf. Funny so many km in only 2.3 months….. On 30.10.1998 there was at 31.700km a new engine at Auto-Becker!!!! 2000-2001 the conversion took place at Dirk Küster in Düsseldorf. The 355 was widened at the rear by about 13cm very nice and conversion tank lid. The whole auxiliary frame with suspensions was rebuilt and adapted. The engine hood had to be completely changed and is a real work of art. Unfortunately, the stability is no longer there, because normal shock absorbers cannot be installed. Heating adjustment Warm/cold is only possible by hand at the front. So far no other solution in sight! Up to now the Ferrari had no handbrake and still Tüv…. The handbrake was retrofitted, the Mot or resealed and large inspection with timing belts etc., front grill after equipped and much more…. The client of the conversion was an older architect from Neuss. Conversion costs approx. 200,000€. He simply wanted a Ferrari where no one else has. Dirk Küster is supposed to live in South Africa by now. That sounds like a real 12 cylinder…https://www.youtube.com/watch?…https://www.youtube.com/watch?v=W5TgFaNqpjA Current problems: Headlights despite cleaning the lenses and conversion on Philips x treme vision, the lamps are still too dark for me! I’m still worried about an engine jerking in the warm state. Maybe just a lambda probe or like my Ferrari screwdriver meant to be old fuel in the tank! With the current shell seats I don’t get a new tuv. I had my car transport trailer widened in the back that my F512GTB now fits and can be transported forward. I have now finally found a few small ramps in order to get there without The mounted Good Year Eagle F1 tires I would like to renew despite good profile, since from 2008. Which tires can you recommend me? LG Tim
