as i told you aswell doyle its a great idea to turbo thye a series, many people have done it before and we all know that it should kill the a series as long as your sensible. i would have to say i have had approx 40kwatw increase and its not even fully tuned it put the pep back into the ute.
-make a shopping list
-take your time and do the research
-stick with lower boost
-go the draw throu setup if your cheap/ go the blow throu setup if you like shinny things(intercooler).
-get it tuned properly
-get the correct fuel pump and fuel reg
-get the turbo with fitting if possible its cheaper
-have fun
-dont be a cheap arse get decent parts
i would suggest setting a budget of around $2000 if your doing it yourself poeople have done it cheaper, i think ianey did it all for $800 or somthing but hes just too cool for school

and got good stuff cheap
