RSR-Style 1974 Porsche 911 Coupe 5-Speed
Presentation
This 1974 Porsche 911 coupe was acquired by the current owner in 2023 and was subsequently modified in RSR-style with steel fender flares, a ducktail decklid, and fiberglass bumpers. It was repainted Gulf Blue with orange Porsche graphics and rides on 15″ Fuchs-style wheels with Koni shocks, extended wheel studs, and power-assisted disc brakes. The 2.7-liter flat-six was reportedly rebuilt and features mechanical fuel injection, a front-mount Elephant Racing oil cooler, and RS-style camshafts. Inside, the cabin houses black leather sport seats, a MOMO steering wheel, RS-style door panels, a Continental CD stereo with Bluetooth, and aluminum pedals. This mid-year 911 is now offered in Alabama on dealer consignment with a Montana title.

Inside, the cabin houses black leather sport seats, a MOMO steering wheel, RS-style door panels, a Continental CD stereo with Bluetooth, and aluminum pedals. This mid-year 911 is now offered in Alabama on dealer consignment with a Montana title.
The car was fitted with RSR-style bodywork during the build, including steel fender flares, a fiberglass ducktail decklid, and fiberglass bumpers. Orange Porsche graphics were added to the lower body, and the window and door trim was powder coated satin black. Additional appointments include a through-hood fuel filler, H4 headlights with black trim rings, Euro-style taillights, and a rear heckblende reflector panel.
The 15” Braid wheels feature an RSR-style finish and are mounted with 225/50 front and 285/40 rear Michelin TB tires. A space-saver spare is stored in the front trunk. The M-type front and S-type rear brake calipers were refinished and the pads and rotors replaced during the build. Koni shocks were also installed in addition to extended wheel studs and Rennline strut tower braces.
The front sport seats were reupholstered in black leather and the rear seat bottoms have been deleted. RS-style door panels, a black headliner, sound deadening, and replacement carpets were installed during the build, and the lower dash pad and ashtray were replaced. Additional modifications include a Continental CD stereo with Bluetooth, JBL speakers, aluminum drilled pedals, and a fire extinguisher.
The three-spoke MOMO steering wheel sits ahead of VDO instrumentation that consists of a 150-mph speedometer, a centrally mounted tachometer, and gauges for fuel level, oil level, oil temperature, and oil pressure. The five-digit odometer shows 19k miles, which is not considered to be accurate. Total mileage is unknown.
The 2.7-liter flat-six features mechanical fuel injection. The engine was reportedly rebuilt during the modification process, and additional work involved installing RS-style camshafts, an electronic distributor, an overhauled MFI pump, a replacement fuel pump, and a front-mount Elephant Racing oil cooler kit.

The motor held this one back. An aluminum case motor, punched out w/ twin spark, and this would have been a completely different auction. Incredibly well executed build, though.

@moley44. At $400k you can get some very unique and well documented builds with 3.6 or 3.8 and g50 trans. One might expect updated brake and suspension at that level. I’m not sure this is on that level. IMO.

Man I'm surprised this one didn't leave for a new home. I was expecting double the last high bid to take it. Although a build like this, if done by ones self could be done affordably. But costing it out to shops would perhaps triple the highest bid? Still as @PORSCHEMAC wisely pointed out and in my own words; "pffft, you ain't gettin out what ya put in". Still this car is awesome!!! And lastly the right bidder will come along, patience is key.

Everyone needs to decide the value they place on any given car and bid accordingly, but the notion that just because a seller has 'more money invested' than any current or final bid as an argument why the car is worth more is inconsequential. They are worth what they are worth.

No surprise. For serious bidders on a backdated RSR style build, one is looking at a minimum of $250K and up. More likely, $300-$400K. No bargains to be had on these given the investment. Good luck moving her on.

We’ve had this car in our shop for some minor work. I didn’t get to drive it and therefore cannot comment on the performance level, but wish I had. It looks like a quality build and should do much better than this. It would certainly cost a lot more to duplicate.

I am laughing at the comments below regarding suspicious bid jumps. Keep bidding. This car is currently listed on Elfer Spot for $367k. My guess is the reserve is somewhere around that number.

Frustrating Yes, but it happens more than you think. Over priced, obviously not, as the buyer sets the value they think it’s worth. @b.flippo -I agree. I have a 2.7 that has 180k in the build and it’s still not finished yet. Right now this golf blue one looks a whole lot nicer than mine. ( unless you flipped them both over )

Give me a break. Anyone that thinks that any bid less than the current bid would actually buy a build of this caliber is delusional, and bidding in 1k increments when you're 50% of the value of something is nothing more than bidding practice. Some of us don't need the practice

What's with all this talk of a special "RS crankshaft"? IIRC, the '73 RS had the same crankshaft as all the '73 2.4L cars. The '73 RS redline is the same as the '73S. Was it lightened or something??
Now, the RSR crank??? That's a different story. Unique and buffed up.
This engine isn't claimed to have a RSR crank, is it?? This is a really nice looking build. No need for inaccurate hyperbole unless warranted.

came to remark on the engine build, but @Frida beat me to the punch, and comprehensively.
not a race car, exactly. very potent and reliable street car. perhaps equivalent to a 'cafe-racer' in the motorcycle world.

Bgs88@Personally, I think 250 hp at the wheels is a bit optimistic for a naturally aspirated 2.7 MFI engine. My expectation would be somewhere in the 210–220 whp range if it's a really well-built motor with good heads, cams, compression, exhaust, and proper MFI tuning.
As for the RS crankshaft, I agree it's a very strong component, but I think the magnesium case becomes the limiting factor rather than the crank itself. For that reason, I probably wouldn't rev it much beyond 7,300 rpm if the goal is long-term reliability. An engine built purely for racing and rebuilt regularly is a different story, but for a car that's driven and enjoyed, I'd rather stay on the conservative side.
The final output will, of course, depend on the complete specification. I'd be interested to know more about the build—compression ratio, cam profile, cylinder head work, valve sizes, pistons and cylinders, exhaust system, and how the MFI pump has been calibrated. The L120/104 cams are quite aggressive camshafts and are well known in the air-cooled Porsche world.
They generally have these characteristics:
Strong top-end power.
Weaker torque below about 3,500–4,000 rpm.
Come alive between 4,500 and 7,500 rpm.
Work best with high compression (10.5:1 or higher), twin ignition, good cylinder head flow, and a properly calibrated MFI or EFI system.
So if his engine has:
L120/104 cams,
twin plugs,
10.5:1 compression,
well-ported heads,
and a good exhaust,
then it's a very serious naturally aspirated 2.7.
That said, I'd still be a little skeptical of 250 hp at the wheels. That's roughly 290–300 hp at the crank, assuming about a 15% drivetrain loss, which is extremely ambitious for a 2.7-liter MFI engine. It would be exceptional rather than typical.
A realistic expectation for an excellent engine of that specification would probably be:
260–280 hp at the crank
220–235 hp at the wheels
Those are still outstanding numbers for a 2.7, and very rare figures, started to build engine in 1982
As for revs, the RS crankshaft itself isn't the issue—it's a very robust forged crank. The limiting factors are usually the magnesium crankcase, connecting rods, valve-train stability, and overall engine build quality. That's why I'd still be inclined to set the rev limiter around 7,300–7,500 rpm for a long-lived street/track engine, even if it is mechanically capable of more.

I would think this engine could easily make 250 at the wheels if it’s set up well. And the RS crank shaft should allow it to rev safely to like 8or 9k!
I’ve got a MFI 2.7 with L120/104 cams, twin plugged and 10.5:1 comp in my 74 Carrera. It’s a super fun motor. Would be good to know a little more about this engine build.

The engine description is confusing - it talks about a rebuilt MFI pump as if it were original to the engine, which came with CIS. Mentions the power output of a stock base '74 engine, which has nothing to do with what is in the car.

This looks like a fantastic build: an RSR-style 1974 Porsche 911 Coupe with a 5-speed gearbox.
The current engine setup is likely capable of around 210–230 hp at the crankshaft. The magnesium case can become the weak point over time, especially if the car is used regularly on track, but it’s also not a bad thing — building another engine down the road is part of the journey with these cars.
If upgrading in the future, I would personally look at something like a short-stroke 3.2L MFI twin-plug or a 3.4L based on a Carrera 3.2 engine with MFI and twin-plug ignition. In my opinion, these setups offer some of the best horsepower-per-dollar combinations while keeping the character that makes these engines so special.
That said, the car is already fantastic as it sits. Once the major work is completed, adding personal touches such as period-correct seats and a few other details would make it even more special.
This is the type of Porsche that should continue to appreciate over time. The combination of this iconic color, the quality of the build, excellent panel gaps, a well-sorted setup, and the classic 15-inch Fuchs-style wheels is exactly the recipe that works.
My personal favorite engine choice would be the 3.4L twin-plug MFI. It offers a great balance of cost, reliability, and incredible torque. Combined with a race-inspired gearbox setup — a longer first gear, shorter 2nd–4th gears, and a slightly longer 5th for relaxed cruising — it becomes an engine and transmission combination that works beautifully both on the street and on track.
Congratulations on a beautiful build. This is one of the most iconic Porsche colors and one of the best interpretations of a classic 911.
