Today I bought the seats I found in Germany. 964 Speedster type with trampoline bottom cushion.
Also bought a roll bar, the original 964 clubsport type.

very nice project! I also own a 964 and live in the same country as you do (i live in the eastern part of holland). Regarding the bolt in rollbar. With that powe and track use r I would consider a fully correctly welded rollcage ( I always would do that instead of a bolt in rollbar which looks nice but can be quite dangerous when in collision). But very very nice project!

Hi, nice to hear from you fellow countryman!
You bring up a valid point. How much safety does the roll bar actually provide? I was under the impression I was adding safety.
It is a Matter roll bar, an original Porsche option.
The reason I opted for roll bar instead of cage is because I use this car mainly on the road and just several times a year on the race track.
Driving a full cage without a helmet is not the smartest thing either...right?

you are definetely right there. I drive with a fully welded roll cage and added padding on the metal parts where my body can make contact with the cage. However, I regularly drive withouth a helmet when I drive on the street. I hesitated for a while whether I should use a bolt-in roll bar or a roll cage. But in the end my choice was to go for a full cage for the extra safety on the circuit plus the much added/very noticable extra stiffnes to the body

Btw, are you familiar with the Dutch porscheforum? Crazy 964 owners there too

I think a roll bar is better than nothing and of course full welded cage is even better. But for now I'll go with this setup. Perhaps later...got to leave something to change in the future!

Yes I sometimes read the dutch Porsche forum, cool people!

There was a RL member selling a 993GT2 gearbox in the 993TT forum a few months back...

Shared post from 'Rennlist Forums' by flipo from thread '993tt engine value':

Hello, my name is Filip and i'm from Belgium .After I sold my 968 turbo rs replica I'm now starting a new project .To make a decision on the route to go I need to get an idea on the value of a 993 gt2 spec engine and 6speed lsd gearbox including gt2 intercooler, oil coolers and EFI ecu .Engine and turbo's are completely rebuilt .I hope someone can give me an realistic idea of the value of this package.

@koenig_roland: the engine part is being done in the far South of Germany, Austrian border. Company is called TTP. They work with other specialists for certain parts, the engine just went to Stuttgart for the work done and they are having the exhaust custom made somewhere.
The turbo's are modified K16's from yet another place.

When the car gets back to Amsterdam I have a local Porsche specialist to do the whole suspension and then the car is off to the interior guys for the final touch.
