yeah he is totally nuts, you are too do some reason lol
that's not too much of an increase in either case we're talking 7-8psi with a good turbo
custom job in a shop will run you a lot of $
If you really want to do it do some research I suggest scionlife forum forced induction forums for the scion tC's as they're running the I4 from our older models, you won't get crap about turbos here,
I'm still looking into mine but short on cash atm looknikg for shops to do a cheaper job o nthe piping but if you're up for it then :clap: I want to see it hehe
if you get all your parts and dont go for too much performance than you need you can probably fit in 2-3 grand if they're brand new and with proper tuning at a shop and piping done by someone else
always see if you can save somewhere jst dont cut corners on tuning if you dont know what you're doing so you don't blow something
good luck
