Yeah, all the T3 Diesels used the same clutch and flywheel.
They are okay for 1.6TD's and standard 1.9TD's but if you plan on any power hikes then it can get expensive.
I used to run a M-tdi and used a Audi A4 TDI flywheel, a LT friction disc and a A4 cover plate, but going this route means you loose your timing marks. You also cannot use the *** shield between the engine and box unless you make a new one and you cannot get to the 2 rear sump bolts unless you machine the back of the flywheel.
Sachs Racing in Germany produce a heavy duty 215mm clutch kit, not had personal experience of it but it is mean to be around the £500 mark.
