Performance Camshaft

not that i recall seeing. it seems that any modifications of the prius engine wind up increasing pollution, which is it's primary focus.

 

right. there may very well be aftermarket performance parts for it, in the non atkinson form.

 

Without the late-intake-closing camshaft and other Prius-y tweaks, it's a plain 2ZR-FE, not -FXE.

Be careful, without the late closing, the 13:1 compression ratio will need aviation gas.

 

Is this a joke? A Prius with a performance Camshaft? I think the primary objective of the entire Prius family is MPGs while maintaining the best performance possible with the least amount of emissions. You know, like a compromise...

 

Swapping in an Otto cycle 2ZR-FE engine will be as cheap, and you can put back the stock engine when you sell it. That will add 40 HP from stock.

I've heard of people putting Gen 2 Prius pistons in Yaris engines for a higher-power engine running on very high octane fuel. Putting Corolla cams on a Prius would give a similar effect, but you'd really want lower compression pistons too, to run pump gas.

(Also worth noting that Toyota put whole Echo engines in the Gen 2 Prius for the racing applications of the Gen 2.)

 

If you increase the power of the engine without changing the capability and programming of the hybrid system (in particular MG1) it will not gain you anything.

MG1 has to balance the torque of the engine and I'm sure will only have a small amount of excess capability.

As noted by the experiments in turbo-charging (elsewhere on this forum) the engine all that happened was that the engine control closed the throttle. I think that was because it sensed that MG1 was not able to balance the system.

Wasn't there the Instagram user PriusZilla swapping his engine components out from a Corolla.

Spoke with @toyotechwv about this similar swap on my car. He said that, "You could but it wouldn't start. When the HV computer spins the engine it's looking for a certain RPM to start, with normal valve timing (otto cycle) instead of Atkinson the RPM would be lower and the ECM would determine a fault and set DTCs. Toyota engineers....the FSP and Landspeed Prii were built by Toyota/TRD engineers who could do whatever they wanted. I even emailed the chief engineer in regard to the customer ECM programming in the FSP car and was told it was a one off custom flash from Japan and could not be released for public use."

So I am conflicted I've been tempted to do this camshaft swap myself but haven't.

 

You'd think the Linear Accelerator would be good for something. Like making element 115?

 

Yeah, but WE have the AXE!

 

My English 1A class in junior college was taught by a guy who got kicked out of Stanfurd for giving football players honest grades. Tough class ...

 

I know that guy. He teaches at De Anza..... He put a cam in his Vespa....

 

Ah, De Anza. I stumbled on a course designed for potential transfers to the Stanfurd football program...

I wanted to register for a class that was really just a treadmill test, but it was full. In order to waitlist that class, I had to be a student, which I wasn't. So I registered for a PE class in bicycling. That allowed me to waitlist the treadmill lab class. So I got into the treadmill class which is what I was trying to do.

As for the bicycling class, it was taught by "staff" at a place I never learned about. I noshowed the first class, assuming that would be an automatic drop. Instead of being dropped, I got an A in the class.

My wife was pissed because she took the same class at another time and got a B in it. I got an A by never showing up...

Just another glimpse at how the real world turns...
