Best 930?

+1 on the 5 speed. IMHO a far superior trans. Bottomline for me though is finding the right car overall & keeping open eyes & mind in searching. Given an otherwise apples to apples choice (which is difficult for improbable these days with all the options & mods) I'd go '89.
FWIW all those mags & their road tests mean nada to me. There is little to no consistency in tires, conditions, drivers, options, etc. Only my own personal experience matters.

Very cool, highlights Porsche's continous improvement on the track and street. Awesome photo.

I just posted this same tread over on the Bird.
First, it needs to be clarified that any 930 is a great car and there is nothing that will take the silly smile from your face once you experience the trill of the car coming on boost.
My 1979 is the finest car I’ve ever driven in terms of sheer driving experience. For me the 4 Speed is more than adequate and you can’t take away the fact that it is strong. I feel as comfortable driving it in town as I do at speed and, whenever I‘m out, I get tons of complements from all ages on its classic design.
So, putting no prejudice aside, I have no problem in proclaiming, you gotta love the '79! There were so many things going right that year for the 911 Turbo and its derivatives. All VIN numbers were 10 digits and still started with 930 (as they had for all of the 930s, 934s and 935s up to that point). It had the big fuel head and the 917 style floating rotor 4 piston brakes. There were no catalytic converters. It had the intercooler tea tray tail and it still had the super neat hand welded front wings and rear welding plates to add the look we have all come to love that is the Porsche 930. And, yes, there were no power seats available in 1979.
How could it get any better than this?

That's what I've been saying through this whole thread !

[QUOTE=The Baron;9860585]Correct on all points except .... only '78 came with 917 style floating rotor 4 piston brakes. '76-'77 had the little "S" style brakes from '73 and '79 actually was the first year that had the "Turbo" brakes which were based on the '78 917 style floating rotor 4 piston brakes.
To clarify, all original '79s (as well as the '78 and the early '80) have the same exact floating rotor/flange/ring assemblies with the same 4 piston calipers on the front axle. All of those, including the '79, are the only 930s that were assembled using this combination. While not exactly the same as, they were all similar in style to, those used on the Almighty 917. Its all part of what makes the 930 early year's racing heritage so interesting.

There was a 930 urban legend that the very first ’78 930’s had 917 ATE calipers but this was dispelled by onboost on the ’78-79 FerrariChat thread (he has #2 of the U.S. ’78 cars).
I’ve also seen on a few threads that claim the very first ’75-76 930’s had RSR floating rotor brakes but this has been debunked (at least for the U.S. cars) after the Excellence article featured the first U.S. 930 with S-brakes.
Urban legends abound with these cars. You can’t trust the web (the VIN sequence is wrong for the ’76-79 cars as they start the sequence at #1) and a lot of claims are unfounded or not supported by the facts.

Well my car has been molested into a horny butch. My car is making 700 chp or 597 at the wheels assuming 15% drive train loss on pump gas, motec engine management, big reds all around with custom proportion bias and larger mc. Matter roll cage, all Ruf gauges, Ruf BTR trim (originally a BTR) G50/50, steel motorsports synchros geared to 209mph, guard differential, billet Wevo shifter, Wevo engine mounts, Wevo carbon fiber strut brace, Wevo camberking, widened Ruf wheels, RSR coil overs , recaro toplines, full fire suppression. Chris and Mike did a beautiful job on my build and I am anxiously awaiting delivery. I am light on details like cams GT2, turbo baby Gt40r I think, reinforced rear shock towers. The details are extensive and I am on my iPad.

Regarding the floating rotors, didn't the early 80s RoW cars also have them?
Btw, I've driven an 83 euro back to back with my us 87, both bone stock at the time, similar mules... The early car was much faster on the old butt dyno.

So one more clarification, the early cars starting in '79 had the floating rotors, did this continue up thru the return to the US market in '86? If not, when did Porsche stop using floating rotors in the ROW cars vs the US cars? I always thought all 3.3 930s had the 917 style brakes.
TIA

Thanks for adding the above brake pictures. They clearly show the difference between the 1978 to 1980 930 floating front rotor 917 style brake assembly as opposed to the much simpler 1981 to 1989 930 front 911 style brake assembly. While the 1981 to 1989 930 front brake assembly is refered to by Porsche as the 911 style, I'm sure this is meant as a reference to the similarity in looks only. The 930 for 1981 up has beefier parts (drilled rotor and stronger bearing and support) than the 911.
The Calipers that were introduced on the 930 in 1978 were of the 4 piston style that was derived from those used on the 917 and did not change through 1989. There are no other changes to the front brake assembly in the 1981 to 1989 time period that I am aware of.
I don't think you meant to say, "All 3.3 liter 930's ('78-89) used 917 style brake discs." The 917 style front brake assembly used on the 930 is only specific to the 3.3 liter for model years 1978 to 1980 (both US and ROW). For the 3.3 liter 930 from 1981 onward (both US and ROW) the only similarities were one, the calipers and number two, the fact that the rotors were cross drilled.

There were some changes to the calipers as well. The Porsche factory workshop manual indicates the brake calipers had modified cast bosses in 1984.
I was using the same terminology that the Porsche factory used to describe the brakes in their 1988 brochure: “To this day, the Turbo’s massive drilled brake discs are directly derived from the 917’s”. As you mentioned, the key difference from the ’78-80 930’s is that in addition to the drilled brake discs, they were equipped with front floating rotor’s also in the style of the 917.
