Alex, the Koni's are 944 parts, so they have those length, I haven't measured that. I ran Koni yellow 944 shocks before.

Work has started already! :)

Very high quality guides ^^

Valve size will be 48x41 and that in just a 98mm bore...:shocked:

Nice eye candy Walter:D

Alu-bronze seats have been made:

Nice! Jacob does good machine work! I like how Thorsten did the rockerbox ventilation.

Looks great! What will your valve size be?

Mythbuster: continuing project thread of my 1303 '75
 

I'm surprised to see you fitting cheap Chinese aftermarket parts to your car Walter :p :lmao:.

Lol,As always impressive stuff going on here. It never ceases to amaze me the amount of expertiese and craftsmanship some people are capable of producing.:notworthy: .

Man, that CNC technology, wow that's just so nice:D

Question, I note that you are at the stud holes, what's the max cylinder size those heads can go up to?

Mark, my valve size (remember mine is just a 98mm bore engine) will be 48x41. Nigel's engine (103x82, as you see in the above pics) has 50x41mm valves.

Francelle, these have stock type 4 pattern and size holes, so what you think is smart/safe to use as a max bore size is entirely up to you. same goes for valve size..

Walter, inside the head, the intake; what do you use to produce that texture? I understand it's for air fuel atomization. Every time I tried to ruff up the intakes, I could never get that result:o

The best surface after porting is to sandblast the port.

Only just saw your post...

For the record: I did not port or machine or do anything to these heads. All work was done by Jakob Spring from Danmark. I mentioned his website before iirc.

My best guess however is that he used a rolled sandpaper bit in a drill or dremel to finalize smoothing of the port, which also gave it that structure.

Finally found one (1, so it was cheap) front left caliper and was sooo curieus if it would fit the 350mm disks...

It did! :D

I see I need to update a bit here :)

Finally got the cylinders machined to fit the heads. I kept wall thickness as big as possible and ended up with almost 9mm wall in the 98mm bore!

First trial fit with heads and cylinders test-assembled:

Looks fantastic!

Wow,it look fast.

looking awesome as always wally!

Very nice.. can't wait to see it all built..

http://i174.photobucket.com/albums/w...1.jpg~original

The (Pauter) rods and straight cam timing gear are ordered, so I should have all parts for the long block in a month or so :)

Wow, didn't know, they allowed porn on this site :D. Very nicely done.

Walter is that a carbon disk rotor you have there, may i ask which hat are you using with the disk.

Walter is this a ortech shroud.

Yes, its an Orratech system. It wasn;t designed for type 1 exhaust port heads though, but thats easy.

The disk hat is original Porsche, but off-set is a few mm short.., so it doesn't work/fit at the moment and I need to adress that issue as well before I can drive again.
The off-set problem is not as simple as it sounds to be though.

On the positive side, I did find the other caliper!

looking awesome wally. cant wait to see this motor running and see what it will put out for power.

Well, since the rods aren't still here yet, I'll thought to start om making the yellow calipers work.
It didn't.. the bolt spacing is bigger (142mm as opposed to the regular 130mm).

So, I started thinking of other solutions.
I kinda strayed towards using the original 996GT3 bearing carriers so the whole thing would fit. That just means adapting all other 3 fixation points: (shocks, tie rod and lower control arm).

Here was a test fit with a rear 996/986 wheel bearing carrier (front and rear are basically the same casting):

Hi, question, ars you going to use struts? I see the spindle hole is splined, is that one is for the rear correct? Your rods, have you ever heard of Gregg Cunningham? He made my rods.

Yes, with (GT3 RS) struts from Sachs racing, also height adjustable and even with external reservoir. The spindle in the picture is indeed a rear (test dummy) spindle, even the wrong side spindle. Its just to get an idea ;)

Heard of Cunningham, but thats it. Mine will be from Pauter.

http://i174.photobucket.com/albums/w...t.jpg~original

This would be nice, but unfortunately it doesn't fit...
Alu one is porsche GT3 rear and just 0,5 kg
Original lower control arm is 2 kg!

Wally--

I like the look of those arms, though having the Porsche moniker would immediately make them too expensive for me, most likely.

I have always believed the LCAs and their inner mounts are the weak point of the 1302/03 front suspension. The mount hangs down a bit, ripe to be smacked into oblivion during an unfortunate off. I think one could create a more stout inner attachment meant for those Porsche rear arms that would accommodate the shorter length. The only immediate issue I see is the lack of mounting for the sway bar, or, better yet, a trailing arm to isolate the sway bar.

If you were to create a mount to use those arms, how would to attach the sway bar?

Good points!
Actually although many have deemed the original LCA's a weak point, I think the construction is pretty solid and a nice combination of a wishbone kind of way combining the sway bar into the suspension set-up.

There is indeed no way to use the pictured porsche parts due to lack of sway bar attachment.
Sooo, I have come upon a small company in germany that makes an aluminium LCA for the late 1303 out of 7075 aluminium. However, his small batch was already sold out. Next weekend I am able to see one of those sets on a new years VW event in germany (Herford).
Of course, I'll try to make a picture of said arms.

Here's the set on Mario Asstmann's reincarnation of a GSR:

and the rest of his car on FB:

I like the look of those. Is that something still available? Are they super (no pun intended) expensive? Oh I saw the link. I will go look.

There is no doubt the original forged arms are plenty strong, but the stamped welded later arms are a weak point. You can stand on them and make them flex. Doesn't mean I won't get them sandblasted, prime then paint with black epoxy paint and use them...I'm just sayin.

Well, what can I say...I went to the german new years meet in Herford and the builder of those arms had 1 set reserved for someone that didn't wanted them after all. Soooo happy with them! Yes they are super expensive. They are also a a tiny bit longer then stock and are still 20% lighter then stock and a fair bit stronger: the material used is some sort of 7075 with a 10.9 comparable strongness. Its difficult to drill he said LOL!

Found the right spark plugs for the heads :)

Those arms are beautiful! Will they fit the 944 spindles?

They are Even more IRL.
Yeah, the outer diameter of the 17mm 944 joints are the same as the 15mm 1303 ones after all right?

However, I want to try and install 996GT3 spindles and the accompanying ball jounts... That will be a challenge, especially as an american bank is holding my funds hostage I paid for the spindles...

Why not just modify the chassis to take the 911 arms?

You think you have all the answers, don't you ;)

Ricola, you're probably right, but those sure are pretty.

Wally, how much do those arms cost (ball park). Being slightly longer than stock, they might just solve my camber issue (n/a 944 spindles). Otherwise I'm going to mod the spindles strut flange to match the dimensions of the 1303 negative roll radius spindles. Also, can you link the source? I did look at the guy's build page but I didn't see a link for those arms.

H2OSB

Don't ask what they cost, pls just don't :o ;)

They are mentioned on his site under 'alu querlenker' but without any details as they are 'sold out' (I got the last set remember :D)

http://bugvision.de/besonderheiten.html

There is an email adres on his site if you really want to know ;)

He says he is out. I tried...
