Bought some Ø10.0mm Chromemoly 4340-bars.
Cut them in correct lenght and cnc-turned M10x1 thread in both ends.
I use Grade 10-nuts and harderned washers to hold the engine in place.

Moment of truth, or point of no return for these housings...
The original "oil-nozzle" must be removed before milling or else my tool, or my housing will be broken.
Started with a M10-bolt and drilled a Ø4.2mm hole to allign the drill.
Threaded M5, and pulled it out with some washers and a M5-bolt.
Machined a Ø63mm hole for the thread, and then removed all stuff the pointed out form the housing.
All done. Next step is the inserts!

Yesterday I continued with my Peripheral-inserts.
Because they are threaded into the housings there is imported to get the D-shape in the right angle to align with the pre-machined D-shape in the housings.
The D-shape closest to the housing are bigger than the round hole and the runners, so therefore I need to machine this with the inserts on the side.
I could have done a round hole in the center, and port the sleeves by hand. But I'm really not a "handyman"
And CNC-port are in my opinion the coolest.
It worked out pretty well! I was really nervous when I mounted the first insert...
I very satisfied.
Next is to deside how to couple the inserts with the runners, and also how my runners will look like, size and lenght. Butterfly-throttles or slides.

Exhaust Manifold Leak
will you keep stock gears in that box? We ran this weekend first time with the samsonas 6 speed dog engagement gearset. I can heavily recommend it. the box also has a overal reduction gear so you can use virtually any rear end ratio you want and order the box with the reduction ratio you want. price is around 4k5 euros. its 50mm longer than stock 5 speed.

Its been over a month, whats going on with this build? I'm loving the mass fabrication here, especially the rotors and cast housings!! How is the small single rotor project going or not going, as the case may be?

Just because it's quiet, doesn't mean it's dead
My old teacher called, he had found my website, and wanted to show his friends my build in person. Really fun! Cleaned up and made some coffee.
Have been thinking about the intake, and have some ideas of how it will be.
I want thin throttlebodys with no injectors, and also buttefly model.
Something like this...
Started on a prototype of aluminium...
The P-Port-inserts will have V-band to connect the runners, but I wanted a personal touch also.
This is how the billet stainless v-band-clamps turned out today. Really happy with them.

No, there is alot more to do before that.
Yesterday I got some mandrels from www.mandrel-bends.com for the intake-
2" 16GA with tight CLR.
Today I did the V-band-flanges for the runners. With a groove to stay concentric and also a little groove on the other side to fix the pipe in. Only 2mm deep, but tight, so it holds there when trying out the parts. Easier to weld also.
