complete rebuild spreadsheet / tool estimator

[Montreal911]

Hi guys,

I'm looking into buying a 911 in a very bad shape for my next project and I'm hesitant at doing so just because I don't *really* know what i'm getting into. Actually I know I will take anywhere from 18-24 months to complete the re-build however I don't know what it will be like financially.

I was wondering if anyone here ad a predefined spreadsheet (or web based tool) that maps at a high level different components to the Pelican website for parts and costs. As an example, the spreadsheet would have the high level elements defined as:
- Exterior/body
- Interior
- Electrical
- Engine & tansmission
- Suspension

The user can select one or multiple elements (ex: suspension), the tool would map out ALL the suspension elements (torsion bar, bushings, tables, etc) and their associated part number and cost. The user could then have an easier task at estimating the work and cost at hand by picking and choosing which items in the suspension he wants to refurbish vs buy. Also, the user can order everything at once instead of putting multiple orders in the system.

I know this site has a similar feature for specific projects but I didn't find anything for a complete overhaul.

I know it's a long shot but i'm convinced i'm not the only one here obsessed with documenting things so anyone has gone through this exercise before?

Been there, doing that...

I will give you the short formula...

EXPENSE:

(Parts cost=5x amount anticipated + work hours X "Way more than I ever thought")X (unexpected expenses such as tools and bigger garage)

to the power of :

"realization I could have bought a new Porsche instead"

Divided by

"Hoped for astronomical appreciation and resale"


=

Lots of fun

Enjoy the journey

It has been said that some going insane after doing the math,

Fixing a Porsche is like golfing, as long as you don't mind spending money paying for the experience its fun.

I "fixed" my first Porsche in college on a shoe string budget. By that, I mean I kept it running.

To properly "fix" or restore a Porsche that's in bad shape, figure 3-5 years of your life and lots of money (depends on skills, etc).

To help you decide if its for you, price parts. If its within your comfort zone, and you have the time, go for it.

Could be lots of fun...

I have an up to date spreadsheet for the machine work done on my 3.0L. It was intended as a tool to track initial quotes vs what was actually spent and to break the work up into rebuild "phases". I just sent out my last top end bits to get redone (rockers, idler arms, cams) so it is basically complete. PM your email and Ill shoot it over.

bpu699, that was very funny and mostly all true. There is a journey there, especially if you do it all yourself.

Also, there is bad shape, and then there is rusty bad shape.

This is dead nuts accurate.

I have something that will get you close. Shoot me a pm and I will email you a copy.

My advice is to buy the best never rusted low mileage 911 that you can find. Do not restrict yourself to "local". It will be the lowest cost in the end (by far).

I tried to rationalize the financial end of my project when I was starting. Once I got going I stopped tracking the money as I thought it would take away from the fun. I have a drawer full of Pelican and other receipts and one day I’ll add them up but not now. I can say the same as others - way more money and hugely more time than expected. This is a hobby for me so I’m keeping it simple and focusing on the fun part - the work.

I do not see how you can rebuild these cars for profit based on the initial cost plus parts and time vs increased value over a few years. That equation doesn’t add up so I just don’t do that math.

[needspeed]

I purchased a used '87 coupe in May and have made significant progress on its restoration. My strategy is to get the car restored to perfect running condition then continually make cosmetic and performance changes. I've been keeping a tab on all the $ I've spent so far, and it's greatly exceeded my expected cost and I've not gotten to the engine yet. :-)

I have to admit I've learned a whole lot about air/oil cooled 911s and it has been a fun, but at times frustrating, journey thus far.

One other nugget of info that I learned after having owned many cars... some pristine, some not.

When I was younger, I wanted perfect cars. Clean, great paint, perfect everything. I would wax my car on weekends, drive on weekends, and never park it for fear of getting scratched or keyed. I was scared to drive my car.

I'm older now. I want my cars mechanically perfect. Cosmetics are less important.

There is an old saying that is true. Not driving and enjoying your car is like not having s*x with your wife/girlfriend and saving her for the next guy...

These cars are a hoot to drive. On the track they will put a huge smile on your face.

Just DRIVE them. Enjoy them. The nicer you make your car, the less likely you are to enjoy it...

[Montreal911]

Agreed! i have a '74 911 that i drive at every occasion I can. I have just stored it for the next 3 months since the regulation here in Quebec is to have winter tires from dec- march.

ok so back to the post, it's pretty much unanimous: initial estimate x5

I got a few feed backs from forums and external quotes and a CS/2.7 engine rebuild isn't lower than $5k for a full rebuild... and can easily double. Transmissions are around $2500 for a rebuild assuming there aren't too many parts to change. So I think i'll do a x3 for the engine/transmission rebuild

I just wanted to clarify one thing however is that I wasn't hoping on making money necessarily (although it would be nice) but more planning and avoiding surprises. At this point, I'm really starting to re-think this and focus on finding a car that doesn't require so much work

+1 on been there and doing that.

You can check out my threads on the Engine Rebuild forum: Another first engine drop - progress to follow
and my thread in this section. 1987 911 Carrera Rebuilding Engine Suspension Brakes and more to come

It started out by learning that I had a couple of broken head studs, then I discovered that I have clutch and brake issues, and it just snowballed from there, and now I have the top end rebuilt with the whole engine cleaned up and bunch of parts replaced, I have all new brakes (rotors, calipers, brake lines, parking brakes etc), the entire suspension is rebuilt with all new bearings and bushings, and shocks installed, all re-usable parts are powder coated... and I am just starting on the body and interior.

The good news is that the body is in decent shape, but the jury is still out on how much of it will get painted, what I do with my targa roof etc..

In terms of prices for stuff, although I have all my receipts I have not added them up yet. It's sort of hard to budget this unless you know exactly what you want/need to do.

Have fun with it!

You are beginning to think in the correct direction, keep going in that direction (see my previous post). "Project" cars can be "fun" but they typically come with a large final price.

If you rebuild the motor yourself then 10k$ in parts, machine work, case work, fan upgrade, etc,etc is probably in the ball park. Figure about a year if you have all the tools and a compliant wife.

If you pay someone, figure 15-20k to do it all...

I bought my 930 eight years ago. Most winters large pieces of it are in pieces as it gets love. Last year was a roll bar and race seats. This year, a motor refresh... I have gotten to the point where I just enjoy the process, and try not to think about cost.

I have wanted a 930 since I was 8 years old. Drew one in all my school books. Made a wood sculpture of it in high school. Drooled overs it's shape since testosterone chewed it's way through my arteries. Whatever money Porsche spent on commercials in the 1980s has certainly worked... If you are of the same mindset, fixing a Porsche is fun...

I still remember this commercial as if I saw it today for the first time
https://m.youtube.com/watch?v=k-gu9f7bH2E

Figure 10-15 weekends a year, 6 or so hours a weekend, and 8 plus years... I literally have over 1000+ hours into this car,and it isn't near perfect.

If I paid myself to work on the car what I get paid at work... Argh. No point in thinking about it.

If you love working on cars, Porsches are fun... But not cheap.

You can go on a website and buy a brand new Chevy v8 crate motor for what you spend on spend on gaskets and miscellaneous items for a motor rebuild on a Porsche...

^^^ or divorced if my wife ever sees the all the receipts for parts I throw into a BIG box in the garage. One day I will add them up but until then as others have stated- it's a hobby, an education and an awesome feeling when you get the car back on the road after working on it.

Minimum of 2x the budget for parts
4x the time forecasted
-50% return on investment
Smiles per mile once completed - priceless

OP, what 911 are you wanting to build?

[gestalt1]

In my experience, as an armature Porsche builder, the 2 big rules are to develope the plan and stick with it and to get the right tool for the job. Changing what you want the finished car mid build means re-dos and traveling off your budget. The right tools make the steps easier and the quality better. Plus, you can sell them for more when done. A third suggestion is don’t be afraid to hire professionals, be a protect manager. Insisting on doing everything yourself, even if it saves money, eats into the timeline and can end up costing more.
