Do both, the port injection for idle/low speed, and staged secondaries in the trumpet for better atomization and I think you even get a bump in power from creating a more dense charge?

 

If I don't charge my own time it will be cheaper to do them myself, but thats really not the reason.
For the challenge! Mazda have already taken care of the design, all we have to do is make it shine

 

I should have my direct injection 13b setup and running by June of this year. I will let you know how much we save on fuel consumption versus power gained with this setup. Should be interesting. I do like the custom cast housings.....would love to do this with DI.

 

Today I've been working on the fixture to the new housings. It also fit stock housings and iron as well.

First up with dowels to match the machine, and countersinked bolts to be out of the way.


Testing with a stock housing to make sure I did it right.


And one of the new ones, let the game begin!




Some motivation

 

You got a thread of that?

 

Damic, not yet. I'm trying to see if it will work first before posting results....results usually help quiet the keyboard tuners.

 

Love that video

 

Haha, lucky that I'm just a SolidWorks-tuner then
It will be fun to see how it works.

Jantore here on the forum has put a injector where the oil-injector used to be on his 4-rotor.

 

Some roughing done!
Looks like it suits! Dowels mounted.

 

 

On your all-aluminum housing, it looks like you've started machining the epitochoroid?

 

Yes, the housings are 89mm thick at the moment, so I could resist to go to zero on both inner and outer contour, just to se the fitment to the irons, and to se If I got the combussion-area right. Everything seems to fit better than expected. I really pleased.
Now it't just to think it all over so I don't forget something important.

Nervous

 

Haha. You know My comment had no direction at you. I am highly jealous of your entire process.

More pics though!!

 

All i can say is WOW!!!! I just read through all 32 pages and this is just amazing. I love the housings! Will the inner liners be able to be pressed out? I have always had the idea of making replaceable housing liners. It would be the last set of housings you would ever need to buy....

 

No, the inner liners will not be able to replace. These are molded into the aluminium and hopefully will stick to the aluminium forever

 

Found a old picture of when we moved in to the new garage a few years ago. How will I be able to drive this?!

 

Today I've used the cnc-lathe again. Fun to learn, but very time consuming.

These are for the 4-link, and fit the RERS-4 rubber protection. I made these in stainless.



Then I also turned a new mount for the rear coilovers.
Really fun to turn threads in a cnc. They always look so good.

M12x1.75 at one end, Ø12.75mm for the coilover, and then M20x1.5 in the other end.





Ofcource I was at the garage to try them out!

 

This build thread is insaine , !
How about 3 spark plugs ,cooling grooves and maybe an aditional cooling port in the hot zone in the housing ,!

 

For you all, this isn't much, but for me, its epic...
After years in a fixture, now he is on his own wheels!
Low...

(My photobucket account will get going soon, they havn't seen my payment yet.)


Last photo in the fixture.


And now on it's own...






Simple Watt-link

 

sweet.......

 

Have also bought me a set of rims that will come in handy in the future.
BBS 19x9.25" Centerlocked Magnesium.

 

That's lightweight :o

This thread is so cool if I only had more tools !!!
