My 912 restomod

Post by jamesm912 »

Alright so here we go with my DIY restomod project based on a RHD, UK-registered MY66 912. It might have started life as a 912 but I bought it as an unfinished project which I believe was going to be a '73 RSR tribute so it came with 11" and 9" wide wheels and full widebody kit. Oh and it was a rolling shell only so I've separately bought a 2.4 MFI (I believe out of a T due to the yellow shroud) and 915 to go in it; both needing rebuilt. Apart from the (5) dials in the dash there are very few original 912 features/parts surviving on it. That's a bit of a shame but I'm OK with it because I want the freedom of a restomod rather than being constrained by adhering strictly to originality and I don't feel guilty about not faithfully restoring what is a fairly early UK 912. I'll be putting it back to a narrowbody.

This is what it looked like when I got it:

Now before I get to describing what I'm aiming to create and where I've got to so far, I need to set expectations of the pace of this project. I intend to try and do the vast majority of the work myself because I enjoy the challenge and satisfaction of the hands-on nature of the work (esp. compared to working in IT for living). I also want to understand how everything works so that I can continue to fix it. I think it might take me getting on for 1000hrs (because I'm slow & meticulous and only modestly proficient on the tools)...and I'm only talking about the hands-on work so excluding the vast amount of research and learning I've got to do. I reckon if I get 250hrs done (in my "spare time") per calendar year then that'd be quite good so I'm looking at 4-5+yrs to finish this with a fair wind and no unforseen significant interruptions :shock: . I tend to get less done in the longer, warmer days because I don't feel like locking myself away inside the garage but on the many dark, cold and miserable Scottish evenings the garage is where you'll find me. So, there may not be so much progress for the coming few months while I make the most of the better weather.

What I am after building is something really classy, traditional-looking narrowbody along these lines:
gulf blue.jpg
I do like a bit of blingy chrome so that will definitely be a feature.

Colour - Underneath the 80s red paint, I've uncovered the original colour. It's a kind of royal blue sort of colour and from researching MY66 912s colours I am fairly sure it is (dark) Gulf Blue (#6603) like the example above. At present I am thinking of putting it back to that original colour.

Wheels - by default fuchs will look great but I might try and go for something a bit different that maybe hints a bit more at the hotrod nature of the car but this decision is a long way off yet.

LWB - one perhaps controversial point is that my car came as a LWB (due to the '73 RSR look) so with LWB trailing arms. I want to stick with that because I like the slightly flared rear quarters of the '69 911/912s. I've done some reading up on Pelican Parts Forum of the ins-and-outs of a SWB->LWB conversion. It's been done and seems doable with modest fettling. I'll focus on this point specifically later on in a subsequent post but early thoughts/warnings welcomed!

Engine - haven't got too far with plans on this yet but would like to ditch the MFI in favour of electronic fuel injection - such as Jenvey Heritage kits - but otherwise keep it fairly stock but probably E cams (DC30 cams maybe?). Really haven't figured much of this out yet though.

Next post (in a few days or so) I'll describe where I've got to and the blocker I've hit that I need help with.

love the blue so deffo go for that

MFI .. dont be too hasty to get rid. If rebuilt and set up correctly its great and keeps the period feel. It might be thirsty at times but sounds wonderful and the throttle resonse is immediate.

Good looking project, should be a lot of fun as you are not strapped down by originality.

The only yellow fan shrouds i know of were engines built by Bob Watson, the yellow (painted) shrouds being a trade mark.
could be wrong!

OK so here we go with where I'm at with the project...down to the shell and up on my homemade dolly.
912 shell.jpg
The laborious process of getting it back to bare metal is ongoing. There's a lot of tarry underseal-type material to remove. I'm OK with doing this by hand because I get to inspect every inch of the thing and so understand what'll need to be done. I am painting the bare metal (or rust-converted metal) with epoxy primer just to stop it "flash" rusting in the meantime until I gear myself up for the welding.

Overall I think the shell is remarkably solid compared to many I've seen pictures of. The worst bits are the rear inner wings and the area around the bumper mounts on the front inner wings with some dodgy previous repairs to all those areas:
rear inner wing.jpg
front inner wing.jpg
The floor pan is solid, if a bit dinged. The inner sills have been repaired a bit crudely. The rear seat bases are a bit rough but I understand the tunnel would need modified to accept the 915 gearbox so that bit'll get replaced anyway. It's had a sunroof delete which looks a bit half-arsed so suspect will have to re-do that.

I haven't removed the wiring loom and I can't decide whether to or not. I think I can work around it as not near any of the major welding (I think) and am not acid-dipping the shell or anything like that but...I know I probably should replace it with a new one (assuming can source one). Does look like a tricky job though. I am simply putting off this decision for now. Thoughts on that? Is it stupid to risk all sorts of electrical gremlins by retaining the original loom? I will need to adapt/supplement it anyway for the modifications away from a stock 912. I think I know where this is going...

So this brings me to the key next step and the blocker I have right now (next post)...

I need to get the shell onto a jig before too long. A friendly body shop contact I have near me (nr Edinburgh) has drawn a blank from his network of pro colleagues. Of course, it's not just the (Celette) jig but the kit that would be needed for a SWB 912 (e.g., the engine mounts are half-way up the engine bay of course).

Also, to avoid having the shell inhabit the jig for ages and because I want to try and do most of the repair work myself (perhaps a little naively, but up for the challenge) I was wondering about the feasibility of simply getting loads of temporary bracing welded into place in/on the shell once its squared up on the jig so that it'll retain trueness while I hack away at some key structural areas once back at home. Thoughts on the wisdom and practically of this welcomed!

So, I'm looking for help with suggestions for places in Scotland that could help me out with this step. Both pro shops and ordinary folks (that just happen to have a jig!). I just don't know where to start. All the well-known classic porsche restoration shops are down in England as far as I can tell. I have a car trailer so can transport the shell on its dolly. Any help/ideas appreciated.

If you want to do the body yourself,id start hunting for a jig.They do come up for sale, yet sell pretty quickly.My last one sold in a week,and i had other offers arriving.
if you dont want to wait,you can check measurements to assure that the chassis is straight.Not ideal, but less hassle and money.,plus you can source jigs for the screen,fuel tank support etc.
You really need to pull the loom and have it rebuilt/restored.Youll save yourself the prospect of chasing gremlins for life.I send my loom to USA for rebuilds.He knows every 911 loom by memory, and does a splendid job, for less money than the alternatives.Just be prepared to wait 6 months

Hi James,
Great Project. Having just refitted my loom I would defiantly recommend removing yours before you go any further, I think you risk damaging it and think you'll struggle to get a good result painting with the loom in.
I removed mine by first cutting off the two 6-pin plugs in the engine bay(not too near the plug!), then removing the pins from 14-pin plug. Taped them all up to stop anything Catching and pulled through the tunnel with some silicone spray to help things along. The plugs can be soldered back on then heat shrinked and taped, easy to recreate the factory loom finish of black insulating tape.

You can then work on the loom as a side project and even power up on a bench and get the thing functional if you want. Good idea to fuse the battery or use a current limited lab power supply(blew my 25A fuse yesterday).

I quite enjoyed getting a better understanding of the 50 year old design and subsequent modifications. There are a few modifications that you might want to implement yourself such as adding a fuse to the instrument lights.

Just my 2 pence on this.
I redid my 73T way back in 1988 when there was no internet, so very much on my own.
Single car garage at home, no jigs etc, but had restored 2 MGBs.
The whole car was well rusty, but I set to on the car.
I checked the truth of the stripped shell using spirit levels and plumb bobs, I checked and checked the shell during 1/2 floors, sills etc and the whole tank area. 9 months of part time work.
I left the loom in place, could not stand the thought of digging it out...

New panels on all corners and door skins etc and it was all back together.
Drove straight and was aligned with ease and no comments by a very reputable specialist, Bob Watson.

Electrically, everything worked.

3 years later I converted the car to rhd using Porsche panels and the original loom. I extended the loom in the dash area to reach the new dash position, soldering iron and heat shrink sleeve.
That was in 1993, everything worked and still does 30 years later.

My point is you can achieve a great deal using simple tools in an appropriate way, it just takes time, effort and a keen eye.
Understand what you are doing and what has to be done.

I would suggest the Peter Morgan book on restoring a 911, lots of good stuff in there for the body side of life.

I hillclimbed the car hard for 13 years and still have it.

Good luck with your restoration, it will have a few bumps along the way, but all very within a keen diy approach.

Definitely remove the loom. You’ll spend more time trying to work around it, not set fire to it/paint it/cut it than it will to take it out.

It comes out towards the back of the car. It’s a crap job for sure (battery cables as well) but it’s OK.

I attached a 10mm nylon rope to the harness at the front so that stayed in the tunnel throughout as a draw to pull it back through again after paint.

Don’t need to remove any connectors taking it out to the back.

Watched a program the other week about building the F Type Jaguar.
They heated the cars loom in a hot box before fitting so the loom was pliable enough to get it into place.
Rather more complex of course..
