I saw no reason to change out the turbo though, because the stock turbo is pretty good with the variable gemetry design and all. overall though if it was up to me, i would totally just avoid turbochargers. Toyota experimented with that for the toyota prius and in the end they decided to go the NA route. |
Do you have any Before and after MPG comparison? I noticed you only have one entry for the fuel economy log. I like your thinking of just lowering the boost.
This Article in Autospeed.com about Turboing a Prius is quite intriguing.
He did see a benefit from the small turbo.
