964 full rebuild and lwt conversion
And the journey begins!
After having owned a nice 3.6T for 5 years, I was looking for a more track oriented Porsche. After a look at GT3 mk1's and mk2's, I ended up going for a 964 again. When ever I was visiting track days or GTC, my final stroll of the day was in between 964's.
I wanted a white car, so the search began for a GP white 964 donor car for my lwt track day car. And here it is!
1989 C2 with 140.000km
Garaged since 2007 and waiting for the right project to come along.
The previous owner planned to build a 3.8 RS, however due to too many other Porsches to drive, decided to sell it as he figured that he had to become 110 in order to finish all his projects.
As you can see from below pictures, the car needs some work and for me ideal as it won't be too painful to transform it into a nice lwt fun and track day car.
Since the pictures have been taken, the car has been stripped:
Before I took of the exhaust system, I did a leak down test and all cilinders
came out nicely, showing 20% using a Sealey leak down testers. ( 20% = fresh engine and tight).
Next post will contain the planned mods for the car.

Interesting.
I have one that looks almost Exactly like that. Waiting for it to come up to a higher rung on the Project Piority Ladder. I am afraid that I, too, may be 110 (2X current age) before it reaches the top of the list. It's so hard to let go.
Curious if you have looked into the details about how the front end structure will have to be restored. In my case, a new frame rail is being recommended.
Good Luck, Have Fun, Be Safe

Just out of curiosity, I was wondering about the details of the crash...what kind of velocity hitting what kind of object does that amount of damage.
Is there a story, ghhally?

Good luck with the build! Projects like this are lots of fun 
And yeah 20% is generally accepted as borderline rebuild territory, but leakdown #'s are pointless to compare anyway unless you are using the same standard (which most in the automotive world aren't - a REALLY good DIY on how to make a FAA-spec tester can be found here). If the reading is consistent cylinder to cylinder, though, that's a good sign.

Thanks for the heads up guys, it has been too long. However progress has been good, given the limited time spent on the car.
No rust to be found!
The ugly bit
Not standard, but when VW came out with the Golf 16V and roof antenna, they were all over the place.
It's a french car, however already imported into Belgium since 2008.
Built end of 1989 = model year 1990.
Standard bottle washer
I don't have the details, but looking to the damage, there's no frontal impact, however impact was on the corner on the edge of the aluminium bumper support. This created the front end off set to the right. At the same time the font lower corner was lifted. Object ? 
I used a leak down tester from Sealey. The dial is calibrated as 20% = no leak. 
Hence all cilinders are ok at 20% with equal readings
