RSR (now '65 2.0l) Race Car Project

Front suspension and steering fitted. All went together pretty easy. Nothing is torqued up yet and I'll probably replace most of the M6/8 bolts with new ones as I progress.

Will start on the rear suspension new week.

A long time since the last update mostly due to being on holiday. This first pic show the parts purchased and refurbished that are bring trial fitted. I've fitted the front half of the FIA fire extinguisher and you can just see the small blue nozzels coming through the bulk head, I'll fit the rearward pipes and the 4 nozzels once i've the engine in place.

The shifter is a 901 Rennsport item - seriously well made bit of kit with adjustable short throw. Handbrake leve and the pedal box have also be refurbished. Alloy plate made for the drivers side floor and a punched alloy pedal board also purchased.

Seconf pic shows the ALT 100L fule tank, i had a alloy cover made to keep the scrutineers happy and have fitted an oil coller and fabricated up some alloy brackets with a mesh protective cover.

Nice work. But im a bit confused. You re-steered from an rsr bcos your car was a rare 911. But one of your pics shows 912 engine points modded off. So was it 911?

To answer you question the shell is rare because it was build in 1965 and can be presented either as a 912 or 911 with the mods i've done.

Furthermore the car was a 912, but i want to race a 911 in historic races and to do that you must have replica of a the car used in the period i.e. 1965. The running gear ie all suspension, steering, brakes are idential to a 911 and were all on the car when i bought it - so easy. The shell was identical apart from the rear engine mounting points and cutting holes in the rear right inner wing to allow fitting the oil tank - the 912 didn't have one in the wing - also the inner wing was already "pressed" to accept the 911 cut outs. The other difference was to cut the dash for 5 dials instead of three. There is no other difference between the 912 of the time and a 911.

Needless to say it will meet all FIA regulations for a 1965 911 so that's what i'm doing. I appreciate there is an argument that i should have built the race car as a 912, but to be frank i also race a 2005 GT3 cup car and this 2.0l 911 is going to be slow compared to that - the thought of a 4 cyl 912 was never going to do it for me.

Cool. I thought for a minute you had changed direction from the rsr because it was a rare 911 shell. Which by chassis #might be more deserving of resto to stock. But As you explain making it of the period as opposed to a later rsr is a cool step to take. Good luck with it - should be a fun project

Rear suspension components rebuilt with new bearings and bushes, 66mm long wheel studs fitted and ARB offered up for final fit before welding in the articulated pins to the control arms. The existing dampers and torsion bars will be used as a start for testing and replaced as and when. Brake pads fitted ready for discs and wheels.

I'll probabaly wheel the car out of the garage to have a look at in daylight - hasn't been "out" for a year now - where does the time go!!

I am now waiting on the engine to land with me then starts the build of that to correct spec, carbs are away to a chap in England who will make them "like new" again. Transmission still needs gears before rebuild but no rush as there is plently of work still to do to the car!

HI - getting on well with the car with fuel cell brackets made, cell now secured in position. Oil lines also installed through the inside of the car using bulkhead fittings through the luggage compartment and also out through the rear right inner panel. A new Mocal thermostat has been fitted which will open slightly earlier than the std porsche one. I also put in my own air blower to aid demisitng even though I've got a heated front windscreen, the blower has a Y piece installed to also direct cool air for the driver. Other little jobs finished such as new windscreen washer system with bottle located in the smugglers box, battery installed also.

Next on the long list of to do's is fitting the fuel lines and brake lines, i'm probably going to opt for a twin master cylinder pedal box as per the SCRS or similar. Carbs should be back with me in a week or so and will then need to start in earnest with the engine and transmission rebuilds.

Nice work, is that a marine "bilge blower" you have fitted? I'm interested since I will need some capacity to demist in my car and was looking for such a thing.

It's not a specific marine blower but i'm sure it's the type of thing that's used. I got mine from demon tweeks and they call it an in line blower. It works with 3" ducting and you can also get aluminium reducers to get the bore down as low a 2".

Coming along nicely, best way to build a car when your not in a rush. What season are you getting it ready for.??? Just out of intrest how long does it take to get it FIA registered??

Thx for your support. I hope to have it ready for next season. It may seem rather far away when looking at the progress so far, but what you can't see are all of the rest of the bodywork painted sitting on the bed in my spare room (wife not overly impressed!) all new glass (except for drop glass) and all new seals for them ready to go in. I don't want to fit any of these until the engine and transmisson are in the car.

The transmission is ready to rebuild except for a couple of special gear sets i want - i can buy them but they're pricey and hoping someone on DDK will have some, or that i strike it lucky elsewhere. All the new bearings, syncros and shifters are ready to go in - so the tranny can be ready in a few weeks if needed. I still need a LSD - same problem - pricey, but will buy one when i have to.

The engine will be with me in the next week or two - this could take some time as we all know to rebuild! The carbs will be back in a week or so also. As I say the fuel and brake lines will go in over the next couple of weeks, leaving the wiring as the last of the major non-mechanical projects left to finish.

I'm not sure how long it takes to get FIA papers - can anyone on DDK help with this? From what i belive it could take 3 to 4 weeks.

One ready I'll race it in my local (Irish) historic race series with a few trips to the UK to race with PCGB in the Club Championship. If the car is competitive at that stage I will enter some of the Master Series for pre '65 salons/GT's

Some work done on the fuel lines using quality braided hose and AN fittings. I'm running twin fuel pumps one to each bank of carbs then returning the unused fuel back to the tank. This is a much better option that using the recirculationg pumps on the standard 65 carb setup. The fuel lines drop down in to the smugglers box and the down the tunnel - to be safe i've used bulkhead fittings in the tunnel area. I've also modified the top plate to accept a std 911 fuel sender.

I also decided to refurbish the dails myself - it was much easier than I thought but getting the bezels of with out destroying them isn't easy and just takes time and patience. I also made the decision to zero the mileage as in essence the car will be new again. I've modified the left dial, it will now have oil temp and pressure rather than oil temp and level. I used some newer white gauges - I'll replace all with correct green ones some time later - don't forget this is a race car no a "correct" restoration - so doesn't bother me as much.

I've also binned the clock and swapped over the fuel guage to that side, the hose coming through the remaining aperture is to supply the driver with cold air.

Engine due to arrive tomorrow!!

Your,re right that the 912 is basicly the same car as the 911 but in order to get a historical Technical Passport you need a 911 Vin number ( homologation 183) , You also need the check App J off this period regarding your rollcage.

Nice job,
Ed

I hillclimb a LHD 911T 1973 for years now and have had occasionally grief from the scrutineers about the hatch to the smuggler's box. You have those two big fuel pumps right next to the lid which I presume is not sealed off, thus there is a direct route for a big fuel spill into the cabin.

Not sure how you rally people deal with this problem, but are you ok leaving it openable??
