Yesterday I was told the LFW in my C2 is actually of a GT3 (not RS). As they were putting in the new heavier clutch they noticed the flywheel was slightly warped. So they ground the surface to make it flat again.

To fit the 964 turbo gearbox they had to fabricate the suspension of the gearbox because it is 30mm longer than the original.

I haven't look at this thread for a while, great to see the progress you've made.
Has it taken longer than expected or is it running to schedule?

Well, you are right, it has taken a little longer than expected. But to be fair, I have added some changes while the work was being done.
I came up with the idea to do the custom exhaust in titanium. This could be done but only by one specific guy. This took some extra time. The gauges too, normally TTP installs a turbo gauge in the center console at the spot where you operate the rear wing. I decided to have the gauges as you see above but it took some extra time to figure out who could do that and to get them back to Germany. Without the gauges the car couldn't be tested.
Also normally TTP modifies the existing gearbox, putting in a longer 5th gear. I decided I wanted a 964 turbo box and this was not a big problem but some custom bracket had to be made. Then I wanted the aluminum intake to be changed to a plastic one. I found one locally but it was white. So they had to make it black and find a throttle housing for it.
Over all the process has been very nice, I am not in a hurry and want everything to be right. In my communication with Ferdinand of TTP I've made clear several times that I rather have everything take longer but done to perfection than rushed. I also understand that they work with many other parties themselves for the production of many different parts. Exhaust, modified turbos, liquid intercooler, all these parts come from separate suppliers for example. And although we ordered some parts in advance, still some suppliers took over two months (before I even brought the car I made a small payment).
This week the car is ready and yet another specialist comes in to do the final ECU programming.
Next week or so I expect to go and pick up the car. When I get back the suspension, body and interior will get done and that will take another 3 weeks. Car should be finished around 3rd week of May.

All these things are quite normal for this type of build from what I can see.

Will keep my fingers crossed for you and the 3rd week of May.

Unless I missed it, how much boost do you intend to run and what are you doing for an engine management system? Enjoy, will be fun!

Engine management is 993, boost I thought would be around 0,8 or something. Not sure, I'll ask and let you know.
