Anthoni has been helping me a lot on the 924 forum. Great guy.

Once car is running well and on road, I'll be looking for some mods to improve HP/Torque, but doubt that headers will be on that list due to $$$.

Want to keep car fairly stock but add M471 pkg. items.

Thanks!

Only problem is this being one of the best car forums on the planet, I'm spoiled by all the great help here.

Only 3 or 4 have stepped up on the 924 board, Anthoni being one. Another, Cedric, in Sweden had ALL original Porsche Shop Manuals in ENGLISH for download! The guys that have jumped in to help all race their cars I think.......what a great resource.

Wish I had the same for my 914.......

M471 option list for the 924 Turbo does sound intriguing ! Please list the goodies when you can / or pM me on message board .

M471 group:

"At an early point in the production it was decided that the car's power required improvement in other areas. So, the 931 “....was built with a limited-slip differential, leather upholstery, air conditioning, power windows, a lift-out sunroof and the coveted M471 "S" Sport Group Package, which included four-wheel internally ventilated disc brakes on five-bolt hubs, mounting forged 16 x 6-inch 928-style alloys (up from cast 15 x 6s). Also included were upgraded springs and Koni shocks, 23mm front and 14mm rear anti-roll bars, a different steering ratio and a leather-wrapped 911SC steering wheel.”

My car has leather front seats and leather-wrapped 911SC steering wheel. Haven't measured sway bars yet.

Local junk car had all this, but sold. Sat outdoors for 10 years. Looking for parts car with this package - and almost ALL 1980 931's had it. Mine is extra rare in that it did not...mine manufactured in 6/79, so in many ways it was a '79 model, but was sold on 5/26/80 and recorded by Porsche as a 1980 model.

Just digging into car today. More good news.

Front sway bar is 23mm and rear is 14mm. Another item to check off list that is not needed. Now wondering if it also has upgraded springs and Koni shocks.......

Car does also have leather front seats in very good condition and leather-wrapped steering wheel. When I get it on the lift I'll check steering ratio to see which it is, but that is not a big deal to me. Limited slip diff? Now that would be huge!

Also has A/C, power windows, a lift-out sunroof.

924 turbos are rare to being with, but yeah, most if not all 1980 models I have seen did have the M471 package, mine does. Seen the 4 bolt setup a lot more on the 79s, perhaps you have a late 79 production 80 model year car? Hard to say, These cars went though so many mid year production changes with limited production numbers across a 3 year period its hard to say what is "normal"

Is your car missing rear seatbelts?

If I recall, one advantage to having the 4 bolt setup is that you are dealing with cheaper VW parts, where as the M471 package parts have porsche PNs (911 SC brake bits if i recall correctly)

EDIT: Just read your early post stating a 6/79 production date... guessing that's why its 4 bolt

[Maltese Falcon]

That's one nice M471 upgrade list @Gatornapper , thanks for digging it up ! This is the 937 (924gtr #0008) that we recently sold. The 2 car (sale package) came with this car and the Sonauto #40 LeMans car. We were only after the 9146...so had a good offer on the GTR, but broke my heart to see her go (IMG:style_emoticons/default/sad.gif)

[Gatornapper]

Cannot believe you let that very rare and priceless car go! Had to be for a small fortune!

I can only admire from a distance.....with great respect..........

James -

Yes, build date of 6/79, but registered by Porsche as 1980 model and put in service/sold on 5/25/1980.

Delighted to find today that my sway bars are indeed 23mm & 14mm.

And yes, think rear seats have no seat belts.

Spoke to another Porsche 931 expert today who said the front brakes are the same on 4-bolt and 5-bolt, but are single piston calipers and to convert to 2-piston 944 calipers.

I don't mind cost of rear disc brakes. Car needs them. Finding them will be a challenge. May go for 944 parts there as well.

These GTRs' were Turbo/ MFI, and on decel the rich fuel mixture threw a decent flame under the drivers door (IMG:style_emoticons/default/biggrin.gif)

[wonkipop]

nice. (flame and GTR).

got me curious enough to check out 924s for sale in aus.
usually just beaters.
suddenly there are two turbos for sale.

one of them looks to be outstanding. a uk car that has come in.
that makes 924 turbos officially an international market car?

Michael,
that's a pristine 924 turbo for sale, dealer service records, once owned by Peter John Vetesse...keyboard musician with Jethro Tull ; good looking deal !

What you have there appears to be a 932... for sure don't see those everyday.

Wow, so this is pretty interesting, just browsing through the 1979 924 PET

https://www.porsche.com/all/media/pdf/origi..._79_KATALOG.pdf

Indeed the rear setup has 944 part numbers. Interesting in that the 944 didnt go into production until 1982. I would think those are going to be really easy to come by given how many 944s were trashed.

yes i kind of figured that marty.
but i don't have the spare 40 odd K. (which is actually a bargain no?).
its funny what turns up here in australia sometimes.
i think it might be one of the best 924 turbos left in the world?
but what can i do.
i blame gatornapper for throwing me off course.
i'm just going to have to stop the distraction.
someone will get hold of that car and look after it.

i do like 924s. i drove a dumbo na one years ago.
they are pretty good cranked out to 95-100mph on a straight stretch of Western Australian highway heading north of perth going up and down over gentle sand dune undulations on a ribbon of narrow bitumen. one of those memories driving thats stuck in my head.
