I think it will be hard for you to hit the 2,300lbs goal.
If tou go 934 look you will have to retain the alluminum front and rear bumpers, rockers, add plastic flares, big wheels etc.

We'll see what numbers we'll acheive with my car, but the interior is as gutted as possible and a 934 will weigh 100-150lbs more.

Still you are easily inside 4.25lb/hp.
Another thing I would suggest is swapping the Motronic for a Motec or DTA. This way you can have the flexibility to run 110 at the track and 91 on the street.

Go for it...

On the weight subject...
 

My 930 is 2820 with about 1/4 tank. It is relatively stock (weight wise) other than removal of the A/C and addition of the 18" wheels (Kinesis K58). I'll weigh it before and after the diet to see how much I can remove by doing the RS thing to the interior.

Any guesses on weight reduction for the interior?

Marcus

RS interior? 30# or less. Rear sound matt and the rear seats are the majority of that. Your easiest weight drop would be a good set of lwt sports seats. You could loose 60# in less than an hr there if you are careful.

LARennsport has been trying to off his twin turbo 964, maybe that is a good starting point? I had a 79 930 with all the bolt on HP mods and a G50 tranny, that car was damn fast. I tought about going through and hot rodding it but ended up buying a race car instead. Sound like a great project keep us posted.

Here is a shot my RSR next to a 935 recreation, makes the RSR look like just another car.

Here's me getting smoked by a 935 clone on the front straight at Sears.

Trekkor,
how many hp do u have, and what is the weight of your car.
WOW!(935)

I'm begging 150 hp? and weigh in at 2400 with driver.
I lifted and got off line when I saw that monster coming...:eek:

Any feedback so far
 

I am about to do the same thing. I have a '79 930 which has a 934 style motor and now it needs the body work to match. I have the flares and the valance and I am going to start fitting them shortly.

I have some questions:

1. Does anyone know what the welting looks like between the flare and the body?
2. How much of the original wheel arch is removed when the flares are added, so pictures would be helpful?
3. The valance has holes for an oil cooler, brake cooling ducts and water radiators (I assume for the originals intercooler?). I intend to use a front oil cooler, any ideas what model?
4. Still on the valance, I thought about fitting some lights into the water radiator holes, does anyone have any better ideas?
5. The flares look like they attach with unpainted chrome fasteners or rivets, does anyone know for sure?

In fact is there a good reference text to look at for the 934?

Thanks

The 2 extra openings int he valance were indeed for the water-to-air intercoolers.

The extra lights is a solution....

I always thought about putting 2 separate A/C condensers up there.
Also what IC are you running? To be true to the 934 your tail will not allow for a big intercooler...

I have heard of people working on a 996 TT style set up, with intercoolers inside the flares...

Looks like a Zuffenhaus type job....

As per how much stock flare is retained after the welding of the extensions... I have no clue...

For the front oil cooler you could go with a setrab or mocal. Go with the bigest avaliable (std 172), it fits perfectly in the opening.

The brake openings are for std brake cooling ducts. You can use AJUSA plates on the hubs....

Post some pics!

I love the 934!

There will be several 934s at Rennsport in Nov. That might be a good time for people to get some detailed puctures. 934s just aren't that common. a lot of them were tranformed into 935s back in the day. Finding a really original 934 maybe even harder than finding an original 935.

These were all race cars. No one gave a ****.

They cared, but it was about staying competitive.
Oh, and after a shunt might as well upgrade.

There's usually a few at the Brian Redman Challenge at Road America in July. You can get up close and personal with the tuners/mechanics/cars in the paddocks.

Take a look at this guy's 934 clone... He did a nice job.

A somewhat unusual 934 clone:http://forums.pelicanparts.com/uploa...1184427974.jpg

When I took the stock seats out of my SC to re-finish them a few years ago I was suprised at how light they were. It might not be cost effective to buy "lightweight" sport/racing seats to save a few pounds. If it's the "look" one's after then that's different.

My power/heated stock seats weigh ~ 55 lbs each...that's 110 lbs. ( 85 Carrera).

If I used 2x shell buckets at 17 lbs each, that would be 34 lbs and a weight savings of 76 lbs... not shabby for a one-change deal !!!

do a search for 'meredithjr' as a partial name. He is building a 934 out of a 930 and posted some pics of it.
