I’m posting here because you guys/gals have knowledge in Porsche, motor rebuilds, motor swaps, parting cars, collector cars, car values, and regular old car stuff. Plus I’m interested in options which may be outside the norm, and not necessarily “save it cause its air cooled”. I am really trying to make the best informed decision I can. I trying to look at this with open eyes.
Back story, the car is a 1976 911 S targa with a 1985 911 3.2. I have had it since 2001, and we drove away from our wedding in it. It has seen very little use in the past 8-9 ish years due to my ever changing interest, and a growing family. I decided to get the 911 back up and in better condition for this upcoming spring. In prepping to do a valve adjustment on the car, I took the valve covers off and a barrel nut fell out. I found a broken head stud on the exhaust side sitting in the head. I put the valve cover back on and went inside to have a beer. From my internet research…it looks like broken head studs are fairly common on 911 motors, and the repair is to do a rebuild.
I did a cost check of all the tools, parts, solvents, etc, I would need and it comes out to $3,700. That does not include machine shop time. Additional issues which seem to be pretty common which are not in my $3,700 total are valve guide replacement, and replacement of the pistons and cylinders if they are out of spec. At that point that $3700 amount quickly jumps to $6000 and that is still if I do all the work myself. Forum quotes 911 forums about having someone else do the motor quickly double that $6000
Mechanically I have torn down a 911 3.0 motor before but, I had already found a chunk missing from the case so it was more of a learning experience than an actual rebuild. I have never done a rebuild. Other things I know about myself are that I do not have an attention to detail. So doing the work itself gives me concern.
As far as the car, here are all the “known” issues besides the head stud:
- Cheap respray, which shows from more than 5”
- Dent in the driver side front fender.
- One cylinder has been welded from a previous broken exhaust stud.
- The interior door panels need to be replaced
- The material on the inside top of the targa bar needs to be replaced
Some good things:
- I’m technically the 3rd owner, 1st had it for a long time, second for a short, then me.
- Collector car value
- Sentimental value
- Some nice parts, Recaro seats, 16x6 and 16x7 wheels, H5 headlight conversion, Momo Porsche steering wheel, turbo tie rods, Bilstein suspension pieces, stainless 2 out exhaust, etc.
With all that said, I am looking for all options to consider what path I want to go. These are what I have already thought of but I'm unsure of most of the cost/values associated with them:
- Rebuild the motor
- Sell the car
- Swap the motor
- Options here are pretty broad, it looks like you can Subaru to LS1 it.
- Part the car
- Not sure about that one
I’m sure there is more I am forgetting but I need to run and want to get this posted.
