One of my 'Must own one day' cars this, love it. Go for the V8 with a blower poking out the bonnet, effortless power and it will have the purists pulling their teeth out!

I can tell you a little about the Saab B204 and B234 'H' lumps that were found in the mid-90's Saabs when Vauxhall owned them, The Saab's of this era were basically Cav's and Vectras with all the cheap crap removed and replaced with over engineered goodness, for example with the correct tuning some swedish loon has got over 600bhp on the standard bottom end of a B204!!!!! Tuning them to 400bhp seems to be dead cheap too, they seem to use the Mitsubishi TD-series turbos which are very tough and easily upgradable. I know the standard ECU can have an additional control board added to make them mappable for not much cash. The sooner the better if you decide to buy one though, the Vauxhall scene has cottoned onto these cheap and overly engineered engines (that had their blocks designed to bolt straight up to VXL gearboxes), they are common conversions now which is bumping up prices for whole cars.

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

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??

Thanks DoogyRev, i've sent him a PM. If he's got his own smilie... he's got to be good!!

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.
