where's the performance products? - Toyota Yaris Forums

The reason you do not see bolt on turbocharger or supercharger kits made is because this engine cannot handle it! Seals start braking down with that much pressure in the cylinders over time. Have we learned nothing from the Scion crowd?

However, that does not mean all hope is lost for the 1NZ-FE. Don't forget this... we all have one thing and one thing only in common. We may differ in every other way, but we can all agree that as owners of this car we have some emotional investment in fuel economy. We're all sick of paying $50+ for a tank of gas, and now none of us have to! Now, what if someone busted out a solution to the power problem... a reasonably priced kit of parts to turn the 1NZ from an underpowered gas sipper into a reasonably powered occasional drinker. This may not be a supercharger or turbocharger... it may be some different internals, a different block and/or some type of engine management, or some nitrous or whatever. Whatever it takes. It all starts with a teardown of this engine and a pow-wow over the remnants. Until you've done that, you have no clue of this engine's proper solution. You're shooting in the dark.

As soon as you take the 1NZ out of the picture, this is no longer a FE-biased car. I'd rather see someone figure out how to make the 1NZ a little more powerful rather than seeing someone figure out how to bolt a 23 MPG engine into a 40 MPG car. It isn't in line with what this car is really about.
