Turbo Questions

[regal]

I've seen turbos done good and bad. For me the beauty of a turbo is that it doesn't affect MPG unless you rev high. A turbo setup done right can have great everyday driveablity and you never know its there unless you need it. The big issue I have found with Turbos is the ECM. With my 93 Civic it was easy, the ECU code was hacked and it could be changed. In my state (Pennsylvania) they scan the ODBII for inspection, no problem with the old Civic.

Not interested in a supercharger, they are fine for racing, but just rob too much fuel economy for my tastes. With a turbo you basically get boost only when you need it if its done right.

What are the options with the Yaris? Can you add maybe 5psi, pass OBDII, and still get 40 mpg if you stay under 3500 rpm? Are there any one stop packages? If not, I'm sure there will be in a few years.

Just interested to know whats out there.
