Bringing Out The Dead.....or how to restore a rusty 914 and convert it to a street/track car when I have time after dealing with everyone elses stuff.

My background is collision and restoration (day job) of high end automobiles for 28 years in addition to race fabrication. I jumped the fence and left that industry to pursue pretty much the same thing except on the paperwork end which is really boring and thankless. (another day job)

I look at rust like a diamond in the rough. Rust is afraid of me because it know's it cannot live in my world. Metal becomes submissive because I have confidence in my metal working talents. I will add to this post as work progress's.

I hope my years of experience can help others as I add. I believe there is a right way to repair a car and wrong way. I metal finish because in the end its cleaner, lighter and stronger. I was taught old school techniques with new school technology. A great combination. I also believe in doing a job once correctly using the highest quality materials and proper tools. Many ways to skin a cat I say. If you hold it by the tail it can still bite!

Good advice to follow:
Take measurements of the door openings and targa bar to windshield header. Cross measure then do it again to confirm. Recheck your measurements against the factory figures. Make a couple of adjustable braces for each side that attach from the upper seat belt anchors to the door hinges. I recommend cross braces also right to left. These can be made from rod or tube and turnbuckles for cheap. Racer Chris has some really nice ones with rod ends. Support the car from below equally on both sides of the undercarriage and front and rear. I do not believe jack stands can hold the proper tolerances at 4 points. It takes a minimum of 6 and preferably 8. These are all easy to do and are essential to a square and level chassis. Not everyone can afford a Cellete bench or hourly frame time at a shop for these type of do it yourself repairs. Impovisation can be done correctly and for a lot less money. Make sure your floor or platform is level.

Keep in mind that tolerances for the 914 were 7-9mm from the factory so anything you can do to make it better is worth it. 7mm by today’s standards is huge. 9mm is a Grand Canyon. Anything you can do to tighten the tolerances will provide a better end product. Exterior panels were fit with the adjust and weld method and are only a skin.

My 914 had measurements all over the place on the front end and the rust issues were all in the rear that needed correction. Car was never in any collisions.
90% of the measurements were factory assembly tolerances. Porsche's aint perfect.

I made my own dedicated bench for 911's and 914's. By some stroke of luck I ended up with a 1 mm variance in height (datum) and 2mm in length and width is zero with my own fixtures. This has been substantiated with endless anal cross measuring and factory manuals. I used a steel front suspension cross member as a front body holding fixture. I went through 4 before I found an acceptable one. The first 3 were so far off factory tolerances (4-6 mm out of square) I rejected them before I found a good one.

My bench is not for pulling. It was designed for assembly and replacement of structural parts. It will support 3,000 pounds. $350 worth of steel and another $175 in industrial castors was worth it considering its use. A stripped 914 shell is a feather and easy to roll around. When you cut and replace structural parts recheck your measurements. Control points change when you remove, replace and weld in new parts. They are easily controlled with patience.

If it does not come out perfect do not lose sleep. Remember tolerance and variance was not perfect from the factory. If you have a control point locating hole that is 14 mm a dowel or pin of 9-10mm was used during birth. That is why suspension systems are adjustable for variance and wear. You will also find center indexing points on the front and rear of the body. Easy tools to use are plumb lines, tape measures and levels if you do not have access to high end measuring equipment. You can locate and make symmetrical measurements throughout repairs. If you have one side that is undamaged or not rusted use that side as a starting point for measurements. Use panel gaps as a visual indicator during repairs and welding.

3 important factors- height, length and width. If you are me then there are 4 (Z axis) and that one will make you lose sleep!
