Hi fellas I work at a machine shop and was wondering about doing some mods to my spare parts and making a motor? I will need lots of help so here are some of my ideas...First i would like to make new apex seals....my own....does anyone know what alloy they use? or do i need to break one of my own in a mass spectrometer? I would like the apex seals to look like an upside down "T" , I can get the rotors laser cut and put the srings underneith so they dont eject into the motor, also what about aluminum rotors? does anyone see a problem with making them, i can get them made...will the housings hold up? I will port this motor and get a new fuel pump and rails, the car is an 86 na. I would love to do just about anything i can do, including making a 4 rotor engine at some point if anyone has the info on how to do that i would like to take a look at it.







Thanks

aluminum will melt, thats why they dont make aluminum rotors/housings. Actually I think there is a layer of aluminum in the housings but they run so hot its fused with the rest. Anyone feel free to correct me, I am not 100% positive what is aluminum in the engine, but I know it runs hot enough to melt it, hence no whole aluminum rotors/housings/irons/seals/shafts.



I have a question of my own. Is it possible to have chromoly rotors, housings/shaft. Its it very light and very strong and temperature resistant.

I think the rotor housings are aluminum, while the plates are iron. A part of the reason it's important to warm your car up all the way before romping on it. Different metals expand at different rates, at full operating temp it's making the best seal.

they used to have aluminum side housings and chrome moly eshafts, but that was too expensive to make, so they phased em out for the r100 in 68.

I would make all aluminum side housings...

in the renisis, have they used more Al? or is it all the same materials as the 13b?

Doesn't racing beat make aluminum side and intermediate housing..

hm, I was told on these forums by a few people with respectable ranks and positions that aluminum was not used because rotaries run hot enough to melt it.



how expencive would chrome moly eshafts/rotors be?

the entire inside of the combustion chamber is cast iron or a chrome. and if all the engines were made out of alluminum which disperses heat well with coolant flowing, i don't see how anything could melt
