Hi Gents,
This is my mate Martins Beetle and the engine in this beast used to be my old 2.0 l T4. Anyway the power this engine delivers is something that can not be explained. When I went back to Germany to visit family and friends, we went on a tour on the Autobahn A3 towards cologne. The acceleration from 200 to 250 km/h is better than anything we came across (including 993 Turbo`s or Audi RS6). I was sweating the whole time as it nearly uses 2 lanes at 250. Top speed is around 270 but the engine revs too high at that speed. Still a lot of fun when you get on the Autobahn on ramp and leave surprised Merc and BMW drivers behind.
This is the second stage of this turbo engine as the first one had problems with leaking cylinder heads, the compression was too high (8:1),the oil galleries too small, the dry sump system not sufficient and the camshaft was a 324 schleicher . It blew a lot of the good stuff out into the exhaust and that explains the picture with the flame . He started to work for the well known company AMG, building racing engines for the DTM and the GT Mercedes and used the knowledge he gained to better his engine.
Heads are 2.0l Vanagon welded intake and exhaust ports, 50 * 40 nimonic valves, compression 7 : 1, 6 studded, bigger oil galleries, oil pump with 50 mm gears on the pressure side, special oil pressue limiting valve and a T belt driven dry sump pump from the Deutsche Tourenwagen Meisterschaft ( DTM ) C class Mercedes. Counterweighted crank, lightened and polished rods from Ahnendorp ( original 2.0l ), Type 1 lifters also from Ahnendorp with sleeved lifter bores and shuffle pinned case. Special head studs and modified cylinders to ensure proper sealing. Pistons and cylinders are mahle 103mm units and can also be sourced through Ahnendorp. The engine has seen many high speed chases and always stayed cool. Recent engine check showed that all internals were like new, it got reassembled and destroyed the transmission. Reason for selling is, he`s got a buisness now and just doesn`t have the time or the nerves to work on it and not that he got tired of it !?
