Wow this thread is just incredible.

Does any have, or know of some actual dwgs of the rotors and housings?
I think a big blueprint would be nice to print out and frame.

Thanks AirJordan223,

I do not think there are any real dwg's out there but i am more than willing to share any of my files if you are interested.

Been really busy with school, trying to get back into modeling this engine now.

Very cool, but instead of having it say Mazda on the housing, why not "SIDEO" ? ;)

Hi Guy's I just stumbled across this thread and must say I am very impressed with he CAD work on show. I also work in design. mainly for composite tooling so I know exactly what goes into to as I have done a number of parts for my own cars over the years!
I was wondering slightly cheekily if anyone would be willing to share a CAD model of the E-shaft for a 13B engine? I am toying with something in my head but need something to pla with and short of cutting one to pieces a CAD model would be ideal. I would also be interested in housing, irons and rotors if my thought looks like it might work. Just to get things spacially right. What is the deal with the 4 rotor design/build I must find that thread! PM me if you prefer.

Thank you
Lee

Hi Lee,

I am more than happy to share all the models I have created. Ill throw out the disclaimer that I have told everyone else ive shared with. I made these parts as close as I could using calipers and other tools but there are undoubtedly some errors so dont expect them to be close enough to send to a shop for machining.

That being said, shoot me a PM and I can share all files with you.

Matt

VERY COOL!! Awesome stuff!!

Thanks!! Hopefully someday I will get the motivation to keep working on this project!

Beautiful Work!

I'm trying to build up enough business to get a FaroArm, so I can do stuff like this guy's doing:

The Engineered 1UZ V8 Datsun 620 Build - Project Datto - Ratsun Forums

There's more on his instagram @3dmagicmike

Post the CAD please!

PM me with your email address.

Wow that guy has some serious talent, I looks like he is doing all that in solidworks too, cant believe it!

Thanks!

Does anyone have files that are pretty close on dimensions? I am looking to build a set for our next project. I have some ideas for doing a set in aluminum using steel inserts on the tips for wear resistance. Thank you.

Good news everyone. I now work at a company that has a FARO arm. Granted, I do not have the experience or skills that 3dmagicmike does but its a start!

This project hit a brick wall when I finished the "easy" parts and got to parts like the front iron, front cover, water pump etc. I am not sure how long it will take me to make solid models but I am compiling a collection of point clouds of all the engine parts. I will FARO scan the parts I have already modeled as well as other parts. The old parts can be tweaked or remodeled using the scans.

P.S. If anyone has any advise or experience reverse engineering from a point cloud I would love to hear it. The local FARO arm rep things 3dmagicmike is using geomagic software, not sure how much that helps in generating solid models. As far as I know it is still a very manual process and the points are basically for reference only.

Matt

Where are you saving all these models? I have a David 3d SLS scanner I could get some point clouds from. I have so of my own models I work from but I only worry about specific items not the whole housing or iron.

I also have access to a FARO arm and a GOM bluelight system if anyone is interested.

any updates

Awesome thread guys, I have access to an SLM at work (basically a metal printing laser), I regularly prototype in Ti64, Al variants, some Cobalt Chromium and regular steels.

I have always wanted to print then machine to tolerance some Ti housings and rotors, given the mechanical properties I like the potential; at first glance I have concerns around thermal cycling and the apex seals but nothing that can’t be simulated and run with some CFD.

Anyway - my question, how accurate are these drawings? Has anyone machined, tolerances, results?

C

This is awesome stuff.. Anyone know the exact upper and lower dowel locations relative to the center line of the E-shaft and what the theoretical nominal value of the dowel land bores is supposed to be?

bump, anyone happen to have this vertical dimension from the exhaust port C-L to the housing bottom/oil pan mounting face?

I don’t have a loose housing to determine if from. TIA.

Bueller bump; anyone?

I suppose it’s not helping that this technical thread is posted in a non-tech forum :icon_no2:
