Lol, this thread is like a 'where were you?' to the people who never considered modding a hybrid before.
There are several fast insights. Im turboing the stock motor in mine for ease/cheapness vs any swap that retains hybrid functionality.
The 1g prius has been modded fairly extensively.. both supercharged and turbocharged, for example, but suffice it to say it is not as mod-friendly as the insight as far as our usual idea of performance goes.
And yes, if you take the hybrid parts out of a 1g prius you have a toyota echo.. weeeeeeeee.
The last high mileage Insight I saw for sale was being sold by the folks who used to service my Civics.
I'll sell you mine with 314k on it for... $8k (i dont want to sell it.
)
