Conversion (73 RSR vs 74 RSR)
 

I am torn on which to go with. I like the long hood cars but I also like the aggressive look of the short hood cars as well. My car is a 92 964 coupe in slate gray which I will keep as the color. One thing I guess I need to check into is a 74 RSR style wheel without having to go with Knock off type. I know there will be a bit more work involved in a correct 73 RSR but I am not afraid of digging in deep. hahaha What do you guys think?

Mike

I actually like the 74 RSR better. If you are using the RS flares, then do the 73.

With the 74, the wider the better. :)

The only issue I have the the 74 RSR is I want to keep it all metal and those intakes on the quarters might have to be made in glass. I guess I could pull it off in steel but glass would be easier. I am not too fond of the glass bonded to the steel.

Mike

Mike- the 74 RSR is the baddest of the bad- with those vented fenders & giganitc wheels & tires it is a black hat dude- as far as the glass vs steel flares I wouldn't be afraid of the glass -it sounds like you do good work- I doubt you will thrash it harder than they were run back in the day & you can find some reproduction wheels that look like the centerlocks.

Truthfully, as great as the '73 RSR is sometimes you need to do a double take to realize what you are looking at but there is no mistaking the '74.

I agree, that 74 RSR is bad to the bone looking. One thing I want to keep in mind is that the badder the car looks the more I will have to do in order to back it up. hahaha I originally wanted to build a RS car but there is no way to get a deep enough offset on a 964 to look good so that is why I am opting to do an RSR.

On another note, do you think the 74 RSR without the vented front fenders is a bad idea? I just do not like the idea of all that glass being on my car even though it may be fine. Now if I could get some glass parts, create a mold, then produce myself some carbon parts I would not shy away from that as I could see that having some value but, just plain old fiberglass is not appealing to me. I had enough fiberglass when I build this car back in 2000. hahaha

You can use 930 flares. The vented flares are RSR 3.0 flares. IROC 3.0 RS actually have the 930 width flares with no vents.

Thanks for that info. So would this be an accurate representation of a IROC 3.0 RS?

Pretty much.

That car looks pretty darn good to me. I am so torn on which conversion to go with.

Mike

Well, I would do 74 mainly because it is easier to do when starting with a short hood (which your 964 is).

Mike- the vents make the car- go all in or nothing at all- as great as the white car you pictured is check out a white RSR- big difference- as for performance you should be able to get there pretty easy- remember that car was built for endurance & passed many a high horsepower prototype pulled off to the side of the track.

Well, I have front and rear flares on the way so I am getting more and more committed to this conversion idea. hahaha I want to keep the car steel so I guess unless I get creative and cut into the steel fares, I will be doing an IROC or maybe still go with a 73 RSR. I figure I still have a little time to decide. the IROC would be less work but, half the fun is working on these cars right? I love a good project so I am not afraid of the mods needed to do a 73. I guess I will start a build thread soon as parts should start arriving soon and I am itching to get started.

Mike

Mike- if there is still reasonable doubt there are pictures somewhere on this website that I have stumbled across before of a Gray '74 RSR with an Orange stripe that will make you change your mind- it is one of the best looking RSR s I have ever seen & I am partial to a white car with red & blue trim.

After seeing your work on the Speedster it looks like you have the skills to build a winner.

I have built two fiberglass cars one being the speedster which was a very old CMC and also a factory five Cobra replica. I have to say I do not miss the itching and poor fit of the parts. I know for this project it would not be near as involved as far as the glass goes but, I just have something against glass now. hahaha I just enjoy working with metal and there is no reason why I couldn't create a 74 RSR in steel even if it was more work I would be more proud of it. hahaha

I figured the speedster would get bashed as its a replica but here are a few more pictures. I built is for my now Ex wife and I went a little overboard on the power plant and it was a beast to drive. hahaha Ignore the shifter and the unfinished look of the interior as I was not finish with it yet.

The speedster looks killer even though it is not an original - I had a '66 Chevelle with a shifter like that- you'd have a unique (meaning more $ when you sell) car if you crafted those vented fenders in steel.

I am going to get the 930 quarters here and see what might be involved in creating the vents in them. Metal work does not scare me one bit. hahahaha

Mike

That's good news-Try to find that Gray / Orange Stripe RSR I was telling you about- or maybe one of the guys can move it to this thread but that car will get you off the fence.

The '73 RSR is a thing of beauty the last real short bonnet race car.

The '74 car is a brutal looking race car . . . . .

Personally I think the '73 car is the more classic Porsche shape (but then I'm biased . . . . ! ! )

The 74 is one mean looking machine for sure. I just am not the type that likes all show and no go though. hahaha. That solid gray 74 is one good looking car though.

Mike

Mike- I agree with you on the looks vs performance issue but keep in mind that despite the ground pounder looks the RSR was not a turbo - both cars were in the 300-315 hp range so regardless of which body you choose you'll have to step up the horsepower-I know it's easy for me to sit here & spend your money but how about that Gray car ?

You have to admit that this is one sharp looking car too. :D

Mike - Sorry but I'm not seeing it but then again my last 911 was a wide body cabriolet that I had the fenders vented with boxed rockers.http://forums.pelicanparts.com/uploa...1300763904.jpg

Hahaha, I just want to avoid fiberglass. Now if I have a pocket full of money, I would go all carbon fiber which would have an appeal to it but when I think of a fiberglass bodied car, It is just not appealing to me. Not saying a fiberglass car can not be built super nice, I just am not fond of it. How could I create the vented front fenders without using glass? So far, all I have on the way are steel flairs and turbo Quarters. I can still go either way with it.

Mike

Take the vented glass fenders & use them as a template for steel or carbon fiber-somebody will buy them after you use them - remember it's a 1974 car & they didn't have carbon fiber or kevlar back then they made it work with fiberglass & were very creative with the bodywork as the car transitioned into the 935 & morphed on from there. To me the 74 RSR is the last of the showroom sillouette cars- even though Brumos made one into a long tail version that was 4 seconds a lap faster than the rest of the field so it was disqualified for the unacceptable body design.

Yes and no . . .

IMO (and I stress only IMO) the early cars look ill-proportioned with larger (17") diameter wheels.

The rear quarter panel shape on the gray car leaves a lot to be desired too, look at the rear arches in the pictures of the yellow '73 car I posted, they're a totally different (and unique) shape. The turbo arches and the '73 RSR arches are NOT the same thing by any stretch of the imagination !

DDK - Die Deutschen Klassiker :: View topic - My new project.........

I agree on the wheels but is there a custom 16" fuch style wheel that would fit over 964 brakes or even upgraded 993TT brakes? I am sure I will be doing a brake upgrade and I bet there are no 16" fuchs that would fit over the brakes as well as have the correct offset. I do agree that the early cars need more rubber showing though.

Mike

Zuffenhaus and Jeff Alton makes 17inch Fuchs. You could always go for 930 brakes (917 derived), those fit under 15inch Fuchs.

But would 930 brakes mount up to 964 uprights and trailing arms? Also, is it possible to have custom 15" fuchs made for the offset that would be needed on a 964 based car?

Mike

I know a UK company makes 964 offset Fuchs replicas.

I would ask Bill Verburg about bolting 930s to a 964. I suspect you can use a caliper adapter at least. Not sure about the rotor.

I think you could get away with some 16" Fuchs replicas, that would allow you to utilise the standard brake set up (maybe with some uprated pads, discs, fluid and lines)

The 17" wheels look almost cartoonish, but I think the 16'' versions would look less so.

Besides that, I want my car to sit nice and level and the taller wheel/tire combo that the 17" will provide cause the rear of the car to sit up too high for my taste. I have been trying to figure out how to get the car sitting level if I am stuck with 17" wheel but it may not be possible unless I lift the front which is not what I want to do. I will be researching the use of 15/16" fuchs on this project for sure.

Mike

Not trying to revive an old thread, but the wheels on the gray car are 18".
