Shalom obsessed)))
Long time no write. Because serious progress has not happened the Current donor has been dismantled. Designed a new intake manifold for the throttles. Now we have to find where to order parts. In the meantime, we sent the cylinder head for revision. Still I will take the camshaft with the intake phase 310 phase 300 of issue overlap is 2.3. Now think on what parts to assemble the engine block..... And not only... In fact a lot of worries. While making the adaptation of the shift lever.

And continue to experiment on the design of the nose and overall appearance.

Congratulations on getting a donor car. That's a big step in the process...

And using a Vaz 2102 as a donor might be a "First" for this forum. Well Done, Sir!!!

The second picture of the nose (the one with the driver sporting a helmet) looks the best in my opinion. The first one looks too square (very much like a Series 4 Seven) and the third one looks a bit flat.

Honestly say that the first picture was done in a hurry. And Yes, it's terrible.

All kind time of day.
So a little about the project. Now going over the wiring and remove all unnecessary. And for one make box under the dashboard. I got the flanges for a homemade manifold under throttle. Yet given the professionals to modify the cylinder head. To broaden the channels, to supply light valve and so on.... I bought a used camshaft, well, a hunchback))

I see how you're using one of the roll cage tubes to support the bottom of the dash panel instead of the usual removeable scuttle. Interesting... that should help stiffen the chassis some.

Lotus made big claims about the tubular dash on the CSRs, but I doubt their bent, small diameter tubes were as strong as your cage tube.

If I understand correctly, you think that the box is mounted on the crossmember of the roll cage? In fact, the box of the instrument panel is removable.

I'm talking about the tube that runs under the steering column.

Good day to all.
I work slowly on the project, I'm working with the wiring. It is necessary to put everything correctly, that nothing would interfere and not rub. Here is another tool bought by the right thing. Well, so for the sake of interest, I printed megaphones on the 3d printer.

The valve close while the piston is on the up stroke. Some small amount of fuel will be blown backwards into the trumpets at idle. On a cold day you can sometimes see the fuel fog, particularly if a high performance camshaft is installed.

It would be a good idea to take one of your bad prints and drop it in a small container of gasoline to see if it dissolves, gets soft, or is otherwise affected.

If the plastic is not fuel-resistant, epoxy paint would work for protection.

Yes of course I'll take this moment into account. Perhaps, then I even cut aluminum.

Finally, I made plates for fixing brake calipers and brackets for steering rods. In one place I was promised to do 2 months and did not. And in another place these details were done quite quickly, but also not to the end. You need to drill the holes for the bolts to 10mm. Tomorrow I'll take it to work, I'll finish it.

Nah, if gasoline doesn't damage the plastic ones, they're fine.

That's some nice looking bracketry you're doing.

And so today I have finally installed all the brake calipers and steering rods. And for the first time he ran the wheels turning the steering wheel 8)

The hole in the middle is the zero Accretion, the hole closer to the disc is positive, and closer to the frame it is refractory.

I love the steering arms! And the inboard shock system looks very nice.
