If I could make the tools to do one-off foundry work, RE-Amemiya could and I'm willing to bet they have machinists who are far more skilled than I (because that's not saying much) Everyone thinks things like this are impossible. It's not as straight forwards as slapping off-the-shelf parts together, or machining parts slightly, but it's not rocket science.

I'm still waiting for someone to break down and make rotors out of something other than cast iron.

 

Cermet-coated aluminum rotors?

 

AlBeMet would be more impressive, as long as you're going to the trouble and all.

 

The next one is supposed to be 1.6L n/a 2 door coupe.

 

thats the double thickness plate, its got a stationary gear and oil drains in it, its not impossible but its harder than say a rear plate

 

Yup, I know. Sure, it's harder... but hell, Mazda was mass producing the things. You could even cheat by taking a normal 20B plate and sectioning it to copy a lot of the internal water passage geometry when you make the sand plugs. Or hell, I know of a bunch of companies (well, I got their brochures anyway) that'll make you parts from various computer modeling formats.

Note that this is too much work for me and I'm not claiming otherwise. Besides, peripheral ports are far cooler.

 

I'd be willing to bet the use of a 20B at such low power levels is for reliability. Turbo cars can generate a great deal of heat and turbo rotaries get quite hot under racing conditions. Given the same HP level and the reduced complexity of an N/A motor I think the 20B makes a great deal of sense.

that heat is why turbos + rotaries kick ***

the heat really gets the turbines going - that's why we have pretty good spool on a single turbo with such low displacement.

 

Kenku, whats AlbeMet? thanks in advance

Aluminum/Beryllium alloy... lighter than aluminum, better thermal properties, and stronger. Also toxic... Mercedes was using it in Formula 1 pistons until it got banned a couple years back.
