2ZZ-GE engine build/design for competition


Recommended Posts

There are not too many aftermarket parts available to build a real race/competition Yamaha 2ZZ-GE engine. The ones that are available are just generic parts adapted to the 2ZZ. The 2ZZ engine seems to be a great starting point in that the block is made from MMC and therefore lighter, more compact and stiffer than a "conventional" cast block.

Would this be the place to post custom designed and made parts for the 2ZZ engine? If not, can this post be moved to the appropriate place?

And, is there any interest in the results?

I finally got the engine block back after Nikasil'ing the bores and silver powder coating of the block.

I wanted a longer connecting rod for the engine, so we ordered custom titanium connecting rods Crower in the USA. And this is what they look like I looked at a lot of pistons, Cosworth,

And here is how the intake assembly will look

Nice! This isn't your first go at this I assume!

Thanks...

I have done individual pieces/components, but never all at once and all together. I'm liking how it is progressing...but it's taking so much longer than I had hoped. But that's how it usually goes, especially with such comprehensive projects.

So, an intake manifold got printed up...and installed on the mule engine...

Another angle...

And the throttle body...

We want to check out if the carbon printed manifold will hold up to the vacuum of an atmo engine first.

I can't wait either. As all new things, It's not going as fast you would like/wish. I still had apprehensions with the last material found and finally found a material that I'm completely happy with. It can even be manufactured the way it was designed to be manufactured. This new material is even stronger than the last one, so to save money, I'm redesigning it again to take into account the better material properties.

Meanwhile, the bottom end is being assembled and flow benching of the head is being done. I've designed intake port to improve flow.

Wow this looks fantastic from the outside, those veins look rather intriguing I'd be more interested in what's going on on the inside???

I'll just say that there are full trumpets on the inside. The injectors point straight to the back of the valves. The volume of the plenum is 2.5x the working volume of the engine. Those ribs on the outside are for structural rigidity. Under full vacuum, the plenum only deflects 0.15mm! The plenum weighs 1.5kg.

I've finally gotten the design to the point where I like it. It meets my criteria for loads. It is 10x as strong as it needs to be and only weighs 1.48kg.

And the max deflection is only 0.158mm at the red spot. You can also make out some of the interior design features.

OK...some movement on this project!
