Looks like a great combo.
Maybe think about M calipers on back with 911 e-brakes and tangerine conversion kit. Not very pricey, especially with your parts supply and would compliment the front brakes.

agree.gif

Or get 914-6 calipers, keep the 914 e brake and get the larger caliper pistons 38 mm, same as m calipers.


Great suggestions on rear brakes. I am not familiar with the Tangerine kit. I would imagine 914-6 calipers would be tough to find.

Since my trailing arms have already been powder coated, my 914-4 calipers are finishing up restoration at PMB and I already have the 911 non-vented rotors that have been turned by 3 mm, I am inclined to keep that setup. Since the car will be primary street driven, other than the visual and cool factor, how much downside is there to the stock 914-4 calipers?

I have stock 914-4 calipers on my conversion car with M calipers on the front. It’s a narrow body with 3.2. My GT car will get S calipers on front and 914-6GT calipers on the rear. The GT calipers are just expensive M calipers with an e-brake. My Suby 3.2 car has M calipers f&r with the tangerine kit. When everything is finished I’ll let you know what works best(for me) lol.

Since you’ve got some items at pmb already, they will be your best source for advice, but if you want to maintain the factory engineered front to rear bias, calipers should be matched as a system. You’re increasing caliper piston size and brake pad size at the front with the early s calipers, so rears should be increased as well. The factory paired M calipers with the S calipers, which is why Mark suggested. Ms are cheap and plentiful, but you lose the stock 914 e brake. The 914-6 calipers have the same size piston and pad as the M, but you are correct they may be tough to source.

There are other methods to adjust the bias, many have gone your path without problems, others use a manually adjustable bias valve. PMB used to offer a 914-6 gt repop caliper, but I don’t see them advertised anymore.

Along with PMB, if you ever want more info on Porsche brakes than you can handle, look up user Bill Verburg on the bird 911 forums.

The case is at Ollies. I am still about 3 months out from delivery. I have almost everything else ready for the build.

More progress on rust repair at Auto Associates. Engine bay L&R (hell hole) side rust repaired. Heater tubes reinstalled and outer longitudinals being replaced. Interesting note on the acid/e-coat dip. We have found some spots where neither the acid nor the e-coat penetrated. Fortunately, these areas also had only light surface rust.

I was able to find some good replacement panels. A LHS sail/rear quarter at Carlisle and a rear panel from our friend Chris Foley. We will use only the taillight section of the rear panel. However, if anyone has a good RHS sail/rear quarter panel like the LHS I found, we could make good use of it.

Front fender well repairs are also completed.

In the meantime, the original '73 side shift gearbox has been rebuilt with a billet Al intermediate plate and 108 mm output shafts to mate with sway away axles and 911 108 mm CV's. The intermediate plate was drilled and tapped to accept the 914-6 throttle bell crank. The gear box will also get the Tangerine Racing precision shift coupler.

Thanks for taking the time to post all these pictures, watching the progress is really fun. Your cookbook sounds great, can't wait to see it all come together. BTW, I know the green color that was your first choice - I would vote for that!

Nice job on those bumper mount areas! I just did mine a couple months ago and it’s a pain in the ass place to work, there’s really no room in there.

I love the hellhole repair method.
Step one: remove firewall.

Great work

Actually, the bottom of the firewall was rusted through. We needed to replace it anyway and we found a NOS panel so the old one came out. It did make access to the hell hole easier.
