I’d contact Gert too. Since he does the conversion, he may sell just the guts. He’s in Belgium, so I can only imagine shipping would be faster and less expensive.
Thank you for the advice, following it I Contacted Gert a week ago but didnt get anything back, I forwarded the same email again two days ago and nothing happened.
Strange because usually he answers in maximum 2 days, maybe he is just in holiday.
So I tried contacting HJS Motorsport directly, introducing them to the restoration, and they chose to help me indicating me and providing the right cat inserts, that... please hold yourself to the chair... are a special Porsche catalysts from the Porsche Cup cars with 100 cpsi and Inconel foil. 😍😍😍
So basically the first exhaust layout will be configured this way, using all the elements from the submerged 993:
- stock primaries, with heat exchangers removed
- stock Bishoff cat box with HJS 100 cells elements
- stock mufflers with internal mods
- stock end pipes
The step 0 engine is going to be the original 3.6 liters, i.e. most of important parts will be the original ones:
- original crankshaft (balanced with SMF and pressure plate)
- original engine block
- original heads, valves, springs, camshafts, cams
- original intermediate shaft
- original fully overhauled injectors
- original engine carrier (reinforced the RS way using the rennline profiles cut to be coupled by welding them)
the lower part of the engine will be 100% same config of the original M64.05 engine, fully overhauled to 0 hours conditions.
The upper part (intake) will be upgraded by installing the varioram intake: I am quite curious how it will be working, since the in/out valves diameters are smaller in the M64.05 if compared to the diameters of the M64.21.
With this type of exhaust and the right engine map, I think the engine should be in the range of 300 hp.
And this would be more than enough, for a stock oroginal engine, that can be easily retrofitted to standard specs just by changing the intake manifolds.
I am now putting together a list of missing parts relatively to system and subsystems and wow... so many parts are requested yet!

I have followed this thread from the beginning and congratulate you on the progress. I have not posted before, but want to let you know that you have inspired a 20-year old from Alaska to rescue this 1995 993 Carrera Cabriolet:
This 993 was parked outside in 2005 in Seward, Alaska, which is located next to the ocean. Limoncella was probably better preserved under water than this car parked outside in a seaside town!

Cheers!
wow! Challenging times are coming!
For what is currently in my technical knowledge, if I can help somehow, don't hesitate to ask meI👍

It's amazing how you are able to find these specialists that can help you complete the car.
How do you name people that are far more than car enthusiasts, let's say car sicks? Car Geeks?
Seeing and handling these cat inserts it is really something special, I can't wait to hear the sound and see how much these cats will help the engine perform the best possible way, with its original exhaust.
Mufflers will have a bypass inside for free flow as well.
what a amazing project that you have undertaken! Congratulations!
Soon it is engine rebuild time: I found a lifter that can raise up the car almost 100 cm, so that I can install the fuel and brake lines back in place, together with oil lines and oil cooler.
I am still waiting for an answer from Porsche, the right department, the Porsche classic one in Zuffenhausen: if participation will arrive, it will be from the USA, again. And I really hope they will participate.
So far here in Europe only HJS by listening and dealing with a private customer and Colin Belton at Ninemeister have been available to provide help, good advice, technical details, while in the USA most of the well known realities are so much participating to this challenging project, I will never thank them enoigh, as I am very grateful, really, these are not just words, not rhetorical at all, towards the whole Rennlist community.
Maybe you will not believe my words, but from a psychological point of view, I am not sure I would have ever be so crazy to go straight to it, if I didn't have this feeling of having an entire and very technically skilled community by my side, that is made from you all here.
So a huge part of responsibility belongs to you! 😛
What seems little and easy for someone who knows and is already passed from certain situation hundreds times, can represent insurmountable difficulties for those, like me, who entered this world for the first time.
Really thank you very much, from the deepest part of me.
I'm really sorry the covid has prevented many of you from coming here to see the car and me also from visiting you: I hope we will make up for all the times we had to postpone.
But, can you imagine?
I am planning to organise a presentation of the car, where everyone who helped in the project with positive attitude will be invited, together with the very Porsche enthusiasts owners, and if Porsche will not be present, it will be for a reason.
There is a time for being a father, as much as for being a mother: there are the biological parents, and the parents who reise childrens up.
Unfortunately and sadly these figures not always coincide.
If one or both of them expect to be recognised as parents after having been 100% absent until the adult age, presenting themselves at the gate just saying "hallo", wearing a nice cloth and maybe bringing also a small fanfare with them, they underestimate that there is still somewhere someone who still undergoes in something not because of commercial, but because of enthusiasm reasons.
At that point, not with pleasure, but no, do yourself a favor, please don't even present yourself.

If you look closely at those HJS cats you’ll notice they employ the triple spiral approach. This helps prevent telescoping of the core material. It’s a real problem in high performance applications. Good stuff right there!

You are crazy! I admire you!
There are drivers, and then there are builders.
Thank you,
I am a normal person, maybe not ordinary, but not in the sense of straordinary.
Related to the second part of your message, I must say I really enjoy driving the 993 fast on the track , not less than the building process.
The fact actually is that I am building the yellow car as a much more track focused version of what it originally was, I have also further development ideas, so that it can become a faster car on the track, for time attack sessions.
Time and luck will say if these ideas will become reality.

yes, high pressure, high temperature, could literally destroy the foils otherwise. I've been lucky finding HJS available to help and also to provide a private customer with their products sold directly.
I think this must be intended as a very rare exception, thanks to the true and genuine enthusiasm that the Company evidently puts into its business.

Like bridges and sky scrapers, the rare situations where a Civil Engineer can turn the structures into architectural and functional beauty at the same time.
