Hey Jim,

Those two will arrive at the same time you get out here:D. Come and think of it, you guys should be any day now?

I added a three car garage on my rental and need to keep that occupy before my wife gets wind of it. It can be packed with her junk, real fast! She can't seem to have enough craft stuff for the kids and their school. She doesn't know about the garages yet, but I have been hinting the built for the past couple years. One of the garage is 14" tall, 16' wide X 20' deep. You see my plan? Lift install maybe next to do a little fussing when needed. I haven't done any work on cars in a very long time. This maybe my semiretirement sanity. I am started to sound like your neighbor, Gill. I think that's his name?

This little 911 just fell on my lap. He lost interest in P cars about 10 years ago, and has been running his private team in races like the Baja 500 and other off road type racing. All his road cars has been sitting on the side line for about 5-10 years now. I know him very well, we ride our bicycles weekly so I am not concern about the quality of the built and he's a solid guy ( I bought the 993 TT from him also a couple of years ago). My only problem is that he doesn't always know or remember what's been done to his motors or what he has around. I just need to learn about these early cars now. That's part of the fun.

Competition Engineering in Lake Isabella or Bodfish, CA? I might call you and pick your brain about the build once you get out here in paradise.

Jeff

We arrived about a week ago. :)

I think it was Competition Engineering in Lake Isabella, but my memory is foggy. I worked with Walt.

Jeff, At the time I had the '77, 2.7L in possession and didn't want to spend more money on another/larger engine. I also wanted to make the 2.7L as long lasting engine as I could. So that's why I had the whole thing finely balanced and the coatings put on the engine pieces. The thermal barrier (ceramic like) coatings went on the piston tops, combustion chamber surfaces, valve faces, and exhaust ports & maybe some other places I've forgotten. They act as a sort of insulating barrier keeping the gasses hot and reducing (supposedly) the amount of heat conducted into the heads & pistons, etc. The dry film coatings are a material deposited on the outer surfaces of parts. They provide a friction reducing surface. I had the piston skirts, bearing surfaces, oil pump, cam surfaces & followers, wrist pins, and other parts coated all of which I can't remember right now. Now since I haven't used it yet, I can't vouch for how good they work. At the time it was sort of the thing to do, but I haven't heard much about it lately. Anyway if these things work, hopefully they will help the engine last a long time. At the time, I wasn't in a hurry to get it assembled and was collecting parts & having things done in preparation for getting it assembled. Eventually a guy in S.D. named Sergio Bartolini did it at Motor Werks. He had been doing Porsche engines for close to half a century at that time. I don't know if he's still in the business anymore.

I bought, then rebuilt a 2.7L......my first build of a Porsche engine......I did get advise on which way to go on several issues from Steve Wiener I had a pile of greasy parts that I turned into a running engine with the help of a local machine shop that specialized in Vdubbs.

It ran strong for 7 years, then got tired so I rebuilt it again with more compression (10:1). Ran strong again till I sold my race car about 5 years later. It did take me about 6 months to hit the combo that those Webers liked.

It's a DIY job for a decent wrench and not nearly as difficult as the folks that want to sell ya something make out. Just don't get intimidated by all them effin' parts.

Wow, I had never heard of such coatings. It sound like a motor that will last a long time. Must be expensive to do.

Of course this was a long time ago. I was astonished when I went back to look at the receipts. The total rebuild cost I had in the engine was about $7.5K with the coatings accounting for $680 of that. The rebuild included new JE pistons, Nikasyl cylinders, springs, ARP rod bolts, along with the usual things that go with a complete rebuild.

I bet today's price for a rebuild like it would run more then twice that?

I have much to learn about these early cars. I hope to see this car sometime this week.
