reckon i might fit one just to annoy the chavs ;) can you use any old valve?
Lawnmower:
mazda RX7 used a twin turbo:
it one turbo, but with 2 sets of blades. at low revs, when producing low amounts of exhaust gasses, these drive a little fan with the blades angled to be most efficient at spinning with low exhaust gasses. as the engine speed increases so do the amount of exhaust gasses, and the fan/blades cos of the fixed angle becomes less efficient at driving the turbo. get to this point and the turbo directs the gases to a bigger fan better suited to lots of exhaust gases and thus = lots of power throughout rev range.
or supercharge it and chuck the turbo.
remember bigger turbo = more bhp, but at expense of lag.
IIRC antilag system works by dumping fuel into exhaust (thus combusting) before turbo, increasing exhaust gases and spinning turbo faster. seems way more complicated to do this then muck about with turbos, particularly if youve alraedy got the know how.

Anti lag in genral shouldnt work on a diesel,
as you are dumping more fuel in to get the tubby spinning when u fuel a TDi up thats what you are doing from the outset,adding more fuel, problem with a derv is when you add more fuel it runns hotter,hotter = melted bits
on a petrol its the other way about.more fuel = cooler,run it lean & melts things
this has to be considered when you try & use petrol tuning on a diesel.
TBH some of the suggestions so far are bloody hard ways of making more oomph & a rather long drawn out process for not a lot of gain,
