Finally, figured out the rear brake set up. Contacted Clint at Rebal Racing Products who felt for my 15×6 Fuchs and 205/50 tires, these aluminum Brembo two pot set are a direct replacements for the M calipers so ubiquitous on 70-80s 911s. Not only are they a direct bolt in to the 3″ bolt spacing rear trailing arms and use the same pads, but they are significantly lighter. It’s supposably, I mean supposedly (…sorry just kiddin pet peeve) from an Alfa but I don’t know year/make/model. Next project is to fabricate all new brake lines from front to rear once I get my order from Fedhillusa.com
It’s amazing how fast some tools break nowadays. I have a floor drill press made in China I got new, less than 10 years ago and it’s already dead! My cousin, Mark has a bench top cool old Atlas drill press that he got from his father and we think came from our grand father, and it works flawlessly. Well I went on a quest to find something similar. Sifting thru craigslist for a few weeks and eureka, a 1940′s vintage Delta DP220 located in Salinas near Carmel. I talked my wife into a short day trip to check it out and then take the coast back. It turn out to be a diamond in the rough w only one missing piece, the front pulley guard. I loaded it up and when I got home, cleaned her up and plugged her in and she runs great, smooth and quiet. I’ll try to track down the pulley cover cuz it just looks cool but for now, I have a drill press I know my grand kids will be able to use.
Besides scoring a nice dp, got some quality time with Jeena. As they say, happy wife, happy life
Rain is a welcomed disturbance to the cycling schedule and working on the car the last few days. Puttering in my tiny shop, I am starting to look around and at ways to increase my usable area. I’ve seen features on Jack Olsen’s amazing garage which houses his ’72 911 and although I have nowhere the same square footage, he has some great ideas. On a search for this article I came across Garage Journal, a site I had visit in the past for another search but this time it just drew me in. Some interesting features on the main site and very creative and resourceful folks on the forum. Just wanted to share the link.
Oh here is a great vid on Jack’s fantastic car and garage artfully done by Pertrolicious.com. Inspirational.
And a link to the a full feature of his garage
Jonesing like an addict looking for a fix, I stepped into the garage today without a project to work on and too wet/greasy pavement to ride on, I needed a project. I decided to learn Solid Works and created my next trigger wheel for the Suby. It will bolt onto the 930 cv and use my existing sensor. The prior subaru transmissions had a speed sensor built into the trans casing but lucky me, that was the year they switched and moved it to the wheel. No biggie since I already had a version of this for the 901. My brother Kris will run it thru his 3D printer and send it up for testing before I have it cut from 1/8 mild steel. Just as an aside, the trigger wheel is not essential for the operation of the ecu/motor but simply tells the ecu that it is actually moving and not just rev’ing without load and tells the ecu at speed its traveling at.
started thinking about it more and perhaps something a tad smaller and just larger than the OD of the cv boot flange and just a few tacks to hold it in place like this
Took the day off from riding to do some wrenching. Chuck at Elephant Racing hooked me up with a set of sealed mono balls for the new trailing arms which pressed in easily with the cheapo harbor freight press (actually been surprisingly useful for many projects). Disconnected the brake lines, calipers and ebrake. I thankfully was able to remove the large bolt that holds each trailing arm in position at the torsion tube while the transmission was still in place!!! Installed everything in reverse. The hub needed to be pressed in, so with a long M12 bolt and a large socket on the opposite side, used the impact wrench to draw it in. Installed the flange and test fit the wheels. I think with the new set up, I might be able to get 7×15 w 225/50 tires in there, please please. Now I can start to measuring things up with the 930 cv joints and determine the axle length. Glad to have things bolted in and this stage nearing completion.
No I’m not converting a chassis but instead, the trailing arms. Why? Few reasons:
1) the brake caliper spacing increased from the SWB to the LWB so that significantly increases caliper selection (any 1969-1989 911 calipers, 930, modified 951 calipers, Boxter calipers w adapters). Of course this too would allow larger rotors. Yes, more unsprung weight but if ya wanna go fast, ya gotta be able to stop fast too!
2) larger 100mm outer flanges allows 930 CVs. Stronger but also allows for upto 20 degrees angulation while the current 94mm allows <1/2 that. The location of the inner flange on the suby trans is slightly forward of the previous 901 flange which causes axle to be at about 5 degrees and the 930 CVs will handle that all day long!
3) larger wheel bearings which coincidentally share the same part number with M42 engined BMWs and for whatever the reason is 1/2 the price.
4) cuz I can't leave anything unaltered ;). Don't worry, Elephant Racing mono ball joints will locate them in place and omit the old rubber bushings.
I needed a new throttle cable since I omitted the stock pedal and the solid bar that ran thru the tunnel. I wasn’t super happy about the prior custom cable because it was quit thick and seemed to have excessive friction. I sourced a custom unit from Pegasus Racing with one end terminated with threaded shaft to attach to the ball and stud for the accelerator pedal. I wanted an 8mm barrel at the other end but unfortunately they don’t have that capability so I just ordered it unterminated. I harvested the brass barrel on the previous unit but needed some way of retaining it. I found several YouTube vid explaining a method where by you drill into a piece of wood, pack the hole with flux and use a torch to heat it up the melt solder into the hole. While it’s still molten, stick the wire cable (cleaned, oil free and it’s end splayed) into the hole with the molten solder. Remove the butane torch and let it cool. After, pull it from the now charred block if wood and you have it ready to shape. Believe it or not , it actually holds! Oh, I also sourced banjo fitting and found that Pegasus had a banjo bolt that I can use for the break light. U can see in the last photo.
Alright, that at should do it. Slight mod to the stock shift rod by cutting it down 1/2″ and corrected the angle so it would enter into the shifter in a flat plane to minimize binding. Welded it back together and connected the shifter to the trans. Can’t wait to test is out. Ok, I think I’ve neglected all my chores for the weekend, better cram 2 days if stuff into 2 hours!
