Rsr or rsr
 

Ok guys, decision time, to go forward or go back? give your vote.
Car is a 78sc which had a warm 3.2, now running a 3.6 with 350 fwhp.
The decision is weather to backdate to 74iroc or forward to 964 rsr, love them both.
Still have the torsion bar suspension (34mm rear, 26mm front), adjustable sway bars, 944s2 front calipers, carrera rears, 915 trans, car weighs in at 2300lbs.
Love the 964rsr , but thinking I will need to go coil over. It seems there has been a lot of backdates, anyone out there taken there sc forward?http://forums.pelicanparts.com/uploa...1433371785.jpg

For resale... I say back date it. Building the iconic 73RS would see the most return.
Although building a 74 IROC would also add value.

I love the 964 cars but your car is "closer" to an IROC and in some ways would be easier to do.

But what do you really want to own?

Go '74 IROC or all-in and go longhood. Backdating is the only believable way to go.

Go back
 

If you must, backdating is the only way to add value to your car. The IROC cars are also "G" type so it would not only make it period-correct but it will be a lot less expensive to achieve correctly. Most forward-dated cars where done in the nineties when long hoods were cheap and "G" models were a dime a dozen and most of these devaluated cars have been turned back to original or backdates by now.
If you like IROC cars, then build your dream IROC monster, you'll be happy and the car will not lose value.

Iroc.

Good post Mr M but to create an IROC he needs to weld on flares.

I still say 73RS... Sure it's almost a cliche but extending the hood and back dating the front guards is easier than welding on flares. The rear mods are simple.
Then there's the issue of the wheels. Correct IROC style wheels can be way over the top $$$.

And it has to be said. There's a very simple reason the pre impact bumper cars have gone up in value they way they have.

Put simply it's the purest of the 911 line. Just the way Butzi intended.

74 3.0 RS or go the whole hog 74 RSR

care to share the engine spec?

Engine details as follows,
93 964 casing
964 motorsports crank
Pauter long rods
Custom JE 12.5:1 pistons
3.8 rsr spec heads & cams, converted to solid rocker
55mm vellios throttle bodies
Autronics engine management
Dual msd ignition.
Lot of fun in a light car!

Go back Jack. Going forward is making the same mistake as all the people with long hoods that forward dated to impact bumpers. Now the cars are worth far less - whereas an IROC tribute would be considered pretty desirable.

The Rs is damn sexy. Im debating that or RUF CTR tribute myself. My vote is backdate 73rs.

Def back.

You could do an SCRS

How about keeping it the same year it was built?

bingo!

This, along with the 3.0 RS I mentioned, gets my vote. That way you get to keep the big bumpers. I'm over the whole long hood backdate thing and glad I didn't do it with my car.


Thanks cuz. Sounds fun!

Tony,
Your 911........as is...is a great "sports purpose" SC rat bastard. Leave it..it's done and done well. Go out and drive that bad boy.

regards.

Keeping it stock will make the most financial sense, but if you must IROC is bad ass!
A 73 rs backdate will need welding to...

My $0.02 is to leave it as-is. It's already a super nice car.

After saying that - you could always add a SCRS rear bumper to match your front bumper, delete the side rocker covers, and maybe delete the flag mirrors and go with a single drivers side 935 mirror or something.

My vote is leave it as is. Swap out flag mirrors, remove rockers, add an IROC wing, call it good. With a 3.6 that thing must fly.

Another vote for SC-RS. Do it as what it is.

What's clear from both choices is that the guy wants girth. And in my experience, that is a point of no return. Were you not to bestow her with some hips, you would forever wonder...

Backdate !

SCRS is my vote. The one in Post #12 is sick.

Girth
 

Ferrino's on to it!
Thanks for the input guys, over the last five or six years of 911 ownership the wealth of knowledge in the pelican community has helped me to tackle pretty much every thing from rebuilding a 915 trans, doing a 3.6 transplant, fitting oil coolers (3 required here), to setting up strings for wheel alignment.
I purchased this car nearly three years ago as a 3.2 road legal track car which had already been modified, after selling my unmolested 84 carrera as I wanted a car I could do evil things to, and couldn't bring myself to cut into my carrera, strange I know.
Car has been in its present format for a couple of years and I am getting itchy feet, I do like running 15" wheels, tyres are a bit of a problem tho, currently maxed out with 275/35 hosier r6 on the rear, if I go iroc i'm thinking 15" braid fuch replics with pirelli p7 corsa classic rubber. The front fenders are already glass so flares not a biggie on that, but if I go Iroc I rely want to have the right shape flare on the rear, not the 930 as it has a different profile, and to top it off i want steel rear flares not glass, here I go again- rambling, this porsche thing is a disease!
I do like the look on water cooled guys faces as I go past.

There was a beautiful IROC-esque car on Petrolicious earlier this week:

lol.... You're a legend

It sounds like you really need to build an RSR. Just go for it.

LOL, indeed..

Clip of how she goes, don't go too hard on the driver, he's a bit of a novice

Great clip Tony. What muffler and extractors are you running?

After reading the posts above I'm thinking Girth now.

The first time I saw a black 930 IRL was more than 30 years ago and I've never forgotten the "presence" that car had.
It was just parked there in the sun... The owner was a kid. Maybe late teens or early 20s. This was in the Northern suburbs of Sydney.

Cheers Peter, BB long run headers and matching 2in & out muffler, not perfect, the droning at 3k is pretty bad.
My aim is to start this project next winter with the car being out of action for as short an amount of time as practically possible, so the next 12 months are about finding and purchasing the bits & bobs, that means making a firm decision on the end result soon.
The tub is much better suited to backdating, so common cense may win the day.
I remember looking at prices across the Tasman a couple of years ago and was shocked at what you guys were having to pay back then for a nice 911, maybe the ROW had to catch up.

Girth is good, or so I've heard...

You are correct about the flares on the IROC/3.0 RS being different from the later Turbo flares. The IROC/3.0 RS flares are the same as used on the 73 RSR, and have much different opening shape and opening size. That Fittipaldi IROC pic shows how much larger the openings are, but when walking around one of these cars, the difference is much more appreciated.

I am building a 3.0 RS tribute and found a set of 4 original correct flares to have installed as seen in the pics. The SCRS makes more sense if you want to keep the turbo flares because they are correct for these cars.

Here are more pics showing the difference in flare shapes between the Turbo/SCRS flares and the 3.0 RS/IROC flares.

The SCRS is a very special 911, with very similar specifications to the 3.0 RS, but their body flares, front bumpers, and tail are different.

It's gotta be blue!
 

Hi Tony. My dream would be to build an IROC replica, and paint it in the blue that Denny Hulme ran. Just to keep it a little more kiwi....http://forums.pelicanparts.com/uploa...1436235846.jpg
Please do that!

Hi Matt, hadn't made the connection with the Hulme car, probably because I've had a fixation on the sahara beige Fittipaldi car. Beautiful car, hope you decide to follow your dream, would make for some great rennsport events with two iroc tributes running.
I will be running the car this summer as it is (a rat), with the wide body conversion hopefully happening next winter, cheers.
