Rebuilding a 962 motor

helidoc · 10-31-2005, 03:01 PM

I have a Porsche 962 that I bought about 10 years ago and restored completely except for the motor which had about 4 hours on it. i ran the car for about 20 hrs in club events and then moth balled the car for about 6 or 7 years now. Since I have a little time this winter I have debated about going through the car again but this time feel that I will have to rebuild the motor. It is a later water cooled engine in which the head and cylinders are a single part so I know it has some differences with the standard 911 motor. However I think it would be a fun project that I am willing to tackle. Has anyone out there on this forum rebuilt one and have any thoughts, tips or good resources (other than your crazy to do it or let a professional do it - with quotes from $35,000 to $135,000 I am willing to take some risks).

WOW! I love the 962. If you are comfortable doing it...go for ! And please, please document the project and share the experience.

You are required to post a large amount of pics and document your adventure completely....as often as possible.......

....I recommend daily.

Where in California are you? I may be able to assist you.

Helidoc, You have uttered words I have dreamed of saying,.....By all means go for it. It is yours do not let some once else get the pleasure, and then ring it out .

I am in the central valley. Usually when I restore or rebuild a car I take lots of digital pictures otherwise I can't remember everything. I will try and post pictures as I proceed. I do want to talk to somebody first though to get a beeter idea of what I am up against. I know it is not rocket science, but every car machine has its own little idiosyncracies and gocha's that are nice to know about before they are going to happen. I was hoping to touch base with someone that doesn't feel like this knowledge is a trade secret and wouldn't mind me picking their brain a little.

Helidoc,
Jerry Woods has rebuilt a lot of these. I have seen them in his shop. Jerry is a good guy and would probably let you pick his brain. You just need to bet by his shop manager Richard.

Paul Weir in Wash has build one from parts. I don't think is was water cooled. Actually he build two. He has a lot of parts for them. Paul is a friendly guy and will talk to you.

Do it your self. That way no one will take any short cuts. If you rebuild you know it was done right. That is a important consideration when you are paying someone else to work on your car. You just never know.

It would be my pleasure to assist you in any way I can.

The 3 most prolific 962C engine builders in the United States are Eric Bloss at Porsche Motorsport (he's the one rebuilding them for HSR if the motor is sent there) in Santa Ana, Steve Becker at B. Precise Machining (former shop foreman at Porsche Motorsport who oversaw the majority of them during the GTP/Group C era) in Laguna Hills and Neil Harvey at Performance Developments in Costa Mesa (former Porsche Motorsports electronics guru who now runs his own business that competes against Porsche Motorsport for 962 rebuilds).

If you want to rebuild it yourself, by all means go for it. But, I would at least talk to one or all three before/during the rebuild as these guys build them in their sleep and have LOTS of experience. I'm sure you've already been quoted by Porsche Motorsport and quite possibly Neil as well. Other engine builders may have built a few here or there over the years, but these guys have built dozens and dozens.

If you need me to, I will be happy to ask them any questions you have on a personal rather than professional level. I also have the 962C engine parts catalog for 1991 & 1992 motors if you need part numbers and such.

Thanks for all your leads and offers to help. I probably will take you up on your offer regarding the parts book if the book I have doesn't cover everything. I also don't understand German very well only having taken one or two years of it a long time ago in high school. Some things are translated in the factory manual and others are not. I think I have talked to Eric in the past when I was getting parts for the car with the first restoration. At that time I think it was a combination of Andial and Porsche Motorsports. Someone else had mentioned Neil Harvey to me in passing as one who might do the motor for a better price than others. I have dealt with Jerry in the past as he had originally been the crew chief on the car when it ran in Daytona and he has also rebuilt a GT4 motor for me. When I was thinking of rebuilding it a few years back he didn't seem too interested and had suggested sending it to Porsche Motorsports. I guess I just need to fight inertia, get things going and tackle things as they come up.

Also of note, I would be interested in what parts are shared with which other 911 motors so if any of you have knowledge of this I would appreciate it if you can pass it on.

Helidoc,

What car/motor do you have? Is the motor a 3.0L or 3.2L? Do you know the Andial engine number (I'm assuming it was/is an Andial motor) since they were the only ones that I know of on this side of the pond building the water-cooled versions for Bayside, Dyson, Busby, Dauer, Moretti, Brun, etc. Joest was having his built by the factory in Germany and not by Andial.

Wow, all the old names pop up from one of Porsche's greatest era's. Up until the total domination of the Audi R8, I thought the 962/962C would go down as the ultimate race car in terms of wins & long-term competitiveness.

Let me know if you want me to make you copies of the engine parts book, it's got pics as well.

I know that Neil is making his own heads/cylinders for the motor rather than using Porsche's, BUT I have HEARD (operative word) of a few motors going south so I would look a little deeper into this if that is what you are considering.

helidoc · 11-02-2005, 12:11 PM

I think it is a 3.2 liter motor and I will have to see if I can find an Andial number on it. I believe that is where it was rebuilt last.

helidoc, are you a helicopter mechanic? I look forward to seeing what happens here.

helidoc · 11-02-2005, 02:04 PM

No, not by trade but do help the mechanic work on mine. I like to know what's going on whether flying in the air or close to the ground!
