There is a some difference in cost if you consider a ceramic ball bearing set up for the TT to have greater reliability avg seen in here is +$2K as an option to be seriously considered. There is much more install involvement with TTs. Intercooler options are abound and will make you dizzy....that is if you are building your own instead of a kit.
PD s/c setups are easier to install, injectors, cam, fuel system, headers, heads, converter should be about $12K.
Both systems make more power and that means more heat and calls for increased radiator capacity add about another $1200 to be safe.
As far as economy goes.....the hp equation will always rule. To get more hp requires more air and more fuel. It is all relative. Turbos can use smaller cams and get away with slightly better economy.
As far as performance the PD s/c will accelerate out of the hole first and be out in front....
that is if 600rwhp is your limiting measure.
TTs can be made to perform but the engine has to stay in the boost rpm which is usually optimal at around 4000 where as PD s/c are in by 2500.
Pick the driving habit or the purpose of the ride.
There is a lot of info here and on LS1Tech. search.
