    You match gearboxes based on desired vehicle acceleration, vehicle weight, gearbox durablity, engine torque curve and engine rpm at cruise.
    It is a topic that needs to be known well in advance of purchase.
    The choice between various 02J/C or 02M/Q then follows, then modifications to integrate.

    You were asking this on the 20VT FB page also today.

    You need a 02M 8N TT or 8L S3 gearbox and transfer case, modified CV shafts, a DMF with A Sachs SRE clutch disc.

    Hotgolf (Martin Emment) is excellent with rebuilding these and badger 5 can supply the clutch.

    I ran a DMF + a SRE clutch from badger 5 and a stock clutch cover on my 8L S3 at 330bhp.
    Badger 5 can advise on this.

    a 6n polo 02j gear shifter is a straight fit to a syncro tunnel, also found on caddy van and ibiza/cordoba/toledo/inca. Look for ones with TDI and 20v engines, and you can get them on the lupo too with tdi and 1.6 GTI engine.

    the 02m cables will swap to the polo unit if you need to, the lengths on them are a bit different to the 5 speed ones. worth having a few cables to experiment with mind

    The same shifter that came with the box.

    Make sure you get all the brackets with it also.
