damn! somebody buy that, and do a massive video about the install with mpg and dyno results. I wish I still had my '04 to experiment on. but alas, the dragon lady would kill me with a cleaver if I had another car sitting around...
There's this story of a guy who put a turbo in a Gen 1 Prius. It looks like an enormous hassle as the ECU and HSD don't easily let you get more power. He has to do a lot of additional tweaks that wouldn't be required on a normal car to get more power. The article doesn't link to future or previous versions, so you can take a read here from the first 5 links: Google Personally instead of undertaking a project like this, I'd instead get a first gen Honda Insight and engine swap something like a 2.0L Honda engine with a Turbo. It'd be possible to get a less than 2000lb. car with more than 300bhp at the wheels with mpgs at least in the 40s.
Quantum didn't ever release turbo kit information because the kit was never for sale. They installed the custom turbo kit to make up for the loss of power when they did their hydrogen prius conversion. Quantum installed this hydrogen turbo conversion on over 10 cars that later got sold in individual auctions. Most purchasers have pulled the hydrogen conversion kit off including the turbo to bring them back to oem spec. This turbo kit is exactly that - a kit that was on a hydrogen prius that was restored back to gasoline. The person selling the kit knows nothing about the kit at all. I know, i've contacted the seller and asked about the engine management system.
A while back i compiled all those links into one PDF because i kept reading it over an over. https://priuschat.com/attachments/1st_supercharged_then_turboed_nhw10_prius_optimized-pdf.56337
I also did NOT pay asking or even half of what this was posted for... otherwise i wouldn't have bought it. Posted via the PriusChat mobile app.
Sounds like a VERY interesting experiment. And I can't help but notice and smile at the paradox -- a turbocharged Atkinson engine.
"Between the Otto, Atkinson and Miller, the particular nature of the Miller cycle permits the forced induction version to not only be moderately more powerful, but also claim better, almost diesel-like fuel economy with lower emissions than the (simpler, cheaper) suction-intake one - in contrast to the usual situation of forced induction causing significantly increased fuel consumption.
