Can someone give me an estimate of the number of hours of labor that a good Porsche shop would require to weld in all of the panels in a chassis-stiffening kit?

You need to find a good welder, not necessarily a Porsche shop.

This really depends. If you just drop off the car and give the kit to the welder, it may take a few days. However, if you prep the areas yourself, make everything weld ready, it should only take a few hours.

Make sure everything is sealed between the plates and the chassis, otherwise it may create secondary problems down the road with rust if it finds an entry way in.

I currently have 3 cars lined up for just this operation, and can do a writeup on it if wanted including hours. It will be a few weeks before I do the first one though. |

If the car was completely ready for the welding I would count on 4 hours, for that process alone. Otherwise the risk of having the body movecomes into play |

I agree, doing the interior stiffening kit really sucked and was time consuming! |

About half the time in fact (IMG:style_emoticons/default/welder.gif) |

Still a tremendous amount of work to be done. The entire rear suspension needs to come out and... you will need some serious welding up behind the quarter panels.
I would be it would actually be "more" time to do the exterior kit properly. The weld area needs to be "CLEAN". |

Holy crap Mark! That sucker is not going to flex at all. I am just doing the inner kit on mine I believe - unless Scott thinks it needs reinforcement elsewhere. Seriously looking forward to seeing this work done on both of our cars.

Michael - If I had a real six, I would go your route unless I was doing a GT clone. |

Last winter I welded in the Engman kit. My interior was already removed and I think the prep time was about 3-4 hours? If I remember right the welding was another 4 to 5. I didn't do it constantly for that whole time. Bending and laying down and twisting to weld all the welds suck at 40 degree temps in the garage. But I was impressed with the fit of the parts and how it turned out when I was done.
If you have any welding skills at all? It really isn't that difficult to do |

When I welded my car and added stress kitting, I spent an entire day on the preparation side and another day on the welding (maybe part of a third day). I used every kit offerred since "I am a frustrated engineer". kits installed: Brad Mayuer Longs, interior cockpit kit, rear suspension inner ears, lower shock/rear suspension to firewall, and seam welding in critical area of the body. Thus, no body flex; requires the suspension and tires to provide more flexibillity and service.
I may add some more stress kitting along the top of the shock mount to the firewall, cross bracing both laterally and long wise in the front, etc. Final suspension changes will determine these needs. |
