I have just done that conversion. I got a second hand TD04L on Ebay for abround €70 or so, and I purchased a manual boost controller to replace the factory electronic unit. The MBC cost €40 inc the carriage and now it goes like stink. The MBC allows you to adjust the boost to just under 0.8 bar which is the fuel cutoff point, but the factory unit only allows 0.55 bar and you will need to get a vacuum boost gauge if you go for the MBC. There is another cheap (free actually) way of getting more "kick" - Remove the top most pipe from the recirc valve on the front of the intercooler and plug the pipe. This is covered in several posts but if you look in "zero boost" under "2.0 turbo engines", there is some info there. If that's not clear, PM me and I will send you finer detail and pictures. The biggest issue changing the turbo was the mounting nuts were seized and a gas torch had to be used to free them, also, the space available to work around the back of the turbo is tight unless you have little girly hands. Other than that, it's not a big deal and for very little outlay (s/h turbo, fitting and MBC+gauge) there is a noticeable improvement. Next step is to get the ECU re-flashed as ours can't be live mapped (Rookie has covered this fairly extensively). Tony.
