that's sort of how i envisioned it would have to be done, hopefully the oil seals will survive. it will also be a pita doing the assembly with all those snap rings and keyways. i suppose you could just build the front and rear rotor housings then slip them onto the prebuilt center section, depending on how you have the lobes keyed.

Havn't calculated so much on that. In stock, the nut have to be hard on because of the taper that can't lose grip. In my case, the spline will have power anyways. Will come back with info on the nut :)

Puh, very very much work everywhere but the garage!!!

Have done some conection-points between my new frame and the original body. The rollcage will stand upon the frame then and be a part of the contruction.

Sorry for the delay!

I'm very interested in this information. Thankyou.

Have forgotten to calculate for you, my bad!
But probobly I will have the standard torque for an 13B-nut, or little less.
If you are going to use an M27x3 nut "all in", the tourqe would be around 930Nm, that is 7965,67 Pound-force inch. Sound very hard! :)

Will come to you about that!

My friend's 4 rotor shaft was made by Jeff Bruce and has splines. Others who've used the Jeff Bruce shafts have said they torqued theirs the same as an OEM shaft which did not sound like a good idea.

From what I can remember, the nut is 42mm or 48mm, not 54mm. Can't recall the thread pitch or the diameter. If I or someone else can give you the specs on the thread pitch and size, could you calculate an approximate foot pound amount we can aim for with an impact gun?

As I guessed before, I don't think the torque is the problem. But now I understand it like you are afraid for the nut to break if you tighten it so hard?

OEM-nut are M36x1.5 fine pitch and therefore the 54mm across flats.
M36x4.0 is the regular pitch for M36 and it holds for 2280Nm = 1681 ft/lbs.
The recommended tourqe for our OEM-nut on 13B flywheel is 350 ft/lbs.

Then you will be able to tighten harder with fine-pitch, but that you already know :)

Standard M27x3, holds for 961Nm = 708 foot pound (foot pound = ft/lbs?) The M27-nut is 41mm across flats from standard.
I will use M27x1.5 fine pitch, and as above, you can add more tourqe then.

Because the nuts we use are lower, about 15-16mm heigh, they will be less tightened, and therefore 13B and myself use fine pitch.
I can look into how much they holds for today:)

Have started to cut away the old misstakes and stock floor. Started to align the new frame with the 4-link. The new floor will aly under the frame, and follow the angle up to the link-plates.

awsome theres almost nothing left of your car

Man this is some incredable work youve done here

It takes much time just to cut off the old junk, and rebuild it slowly so the shape won't change. Have spend some hours today cutting the old frame I build long ago, and slowly design a new, better one.

Much pics of small changes, but it's always something :)

Despite the low interest I update a bit

The rear frame have been tried out. Missing a little piece of pipe to finish. Will try to do some nice radius on the last part.

Started on the tunnel instead. Tight and as low as it could be. With drysump, it will be lower.

Mounted the board also to se how it looked, and I'm satified. Will try to use the board in the final also.

Did some paper-template to illustrate the floor.

And again to illustrate, or something ;)

looking great! keep up the good work!

Fantastic work keep it up !!!!!!

I think there's more interest than you think, just not a lot of people posting to say so. I don't know if I've posted in the thread before, but I've been following it for a while. I'm sure I'm not the only one.

Nice to know that I'm not lonely in this thread then :)

wow. glad to see you getting back at this thing!! its going to be a beast whenever you get it done sir!! very nice

;)

Downright amazing build.... and that's an understatement.

+1 I think ive been following this thread since page 2 I think. keep up the great work!

Awesome fab this is so sick, cannot wait to see this project finished!

I think everyone is dying to see more of the engine, I'm sure a hundred people check this all the time to see if there's new posts.

looking awesome as usual :D

Oh, thanks!

The engine-update will be a little while. Have some issues to handle there berfore I can send it away for first grinding-session. Thats why I build at the chassi and body instead :)

+1.
Really awesome project.
I may be quiet, but i really enjoy reading this thread.
