sussexa ? would you be able to help me ? mines a Stilo 1.9 Jtd 8v

im affraid its a question of how much power you want and more importantly how much you want to spend.
the turbo wouldnt be the end , other stuff might start breaking plus cost of remap etc to take into account larger turbo control issues on vnt.
i have managed to get to 200+hp with my modified gt1749v made into a gt1752v hybrid and theres a few 8v that have gone gt1756v hybrid.
ill try to find some turbo threads and stick in here.
even the jtd16v turbo is supposedly a mild upgrade for the 8v due to slightly larger vnt vanes but does require new studs/ holes to match ports and a bit of porting.
im sure someone did this also on alfaforum possibly yanko

heres a jtdm 8v turbo thread

from enquiries a while ago hybridised std turbo to say cutback turbine and 52mm or 56mm compressor in larger housing or machined larger to suit should be looking at £400-£600

adam at tdi turbos would be good to ask

turbine and compressor wheels numbers should be listed in there they may fit the 8v also?
adam will give a good honest answer for you
