Ah good, even more reason to pursue the conversion, does anyone know if the manifold and turbo unit from a 1.8t fits the 2.0 head then, i don't want to sell my wee baby,a s i'm passionately in love with it, it makes me smile every time i look at it, drive it and talk about it, would break my heart to part with it as we have a bit of history, ye ken, its only 8v and 115bhp. would hardly describe it as pish but do admit it needs a bit more go. 
You can get about 160/70 reliable bhp from a turbo 8v and lot of torque, can get more but it comes at a price.
Popular conversion in the states with the cross flow engine and kits are available on line, not sure if you can swap the cross flow head onto a UK spec block and take advantage of this.

Not sure if this kit is for x flow, but being from the states I suspect it is......
You need to think about compression and engine management to get it to work as well.
Would be nice to see an 8v turbo, I worked on a Mk2 with a turbo running 190bhp which was epic (when it was working
)
Its easier and more fruitful to stick a 20vt in, but then the fun in working on cars is what its all about as there is always something better to stick in or an easier engine to mod.
Your money at the end of the day
