Johnny_A Posted December 19, 2012 Share Posted December 19, 2012 (edited) Hello 350/370Z peeps! I have joined your site in a search for a clutch that can handle over 400lb's of torque, take a lot of abuse and still being drivable. I am close to a solution using a 350Z pressure plate as it's a good size, I do however think it's rude to just join and start asking questions. So for anyone interested here is my Vauxhall Carlton. Basic spec: 1993 Carlton Estate 2.0 8v base shell Senator front end conversion (wings, bonnet, headlights) Z20LET (2.0 16v turbo engine taken from a 2001 Astra coupe) tall engine producing 347bhp Greddy TD06-20G turbo @1.1 bar with a modded SR20DET top mounted manifold, Tial 38mm external gate with screamer Sierra Cosworth FMIC, custom pipework and exhaust system, Siemens 630cc injectors, various other minor mods Omega 5-speed gearbox with a 228mm paddle clutch Totally custom built dual perch coilovers front and rear based on the Opel Omega touring car with road and track springs Monaro rear diff and shafts The current clutch is already over the recommended torque limits, it's a 6 paddle design and horrid to use as a daily driver. If I went to a 240mm organic friction plate it would handle the current engine output but as normal I want more power! I am already in the process of adding a small Eaton M45 supercharger to the design to compound charge the engine, the lag is a real pain and I want rid! In addition I'd like to pump up the peak power to 400bhp with similar torque, any more than this and the gearbox will fail. I've been looking at friction plates around 250mm to handle 400bhp in an organic form. With the help of google I was able to determine that 350Z's use 248mm OD friction plates which is close enough!! So in theory the pressure plate should just about shoehorn into the gearbox bellhousing. Any help with pressure plate dimensions would be a great. John.

Johnny_A Posted December 20, 2012 Author Share Posted December 20, 2012 Thanks guys, Zmanalex has replied and is very helpful. I happened to be up at Horsham Developments near Newbury today, Mr Horsham was able to show me a 350Z flywheel and clutch, I didn't have a tape measure to hand but I can always go back - however by eye it looks perfect for me. But I do have a question, there are two types of 350Z clutch but what are the differences?? Quote Link to comment Share on other sites More sharing options...
Lexx Posted December 20, 2012 Share Posted December 20, 2012 The 350 comes with 2 engines. One was for 03-07 cars, and the other 08-09. Clutches we're different to allow for the difference in engine/gearbox and added power in later engines. Quote Link to comment Share on other sites More sharing options...
Johnny_A Posted December 20, 2012 Author Share Posted December 20, 2012 (edited) So in theory anyway the later clutch design should be able to handle more torque, so I will focus on them. Horsham Developments carry both types in stock Edited December 20, 2012 by Johnny_A Quote Link to comment Share on other sites More sharing options...
