Seeking input on ROW/German Spec 2.7
 

This is my first thread even-though I've had my 911 for 15 years, 'hello everybody'.

And thank you for the terrific community and resource.

Couple questions below about my German spec '77. It was sold new in Berlin to a US serviceman and brought to the states in '79 per the import door tag.

Can someone describe the engine difference between this model and a us spec. I understand the thermal reactors were not required and there is a difference in compression on the German 2.7, but what else? Pistons? Fuel system/injectors? Cam profile?

Any gearing difference in the 915?

A side note that I'd like some feedback on.....my car FEELS quicker and more nimble than both the '84 3.2 Carrera US spec and '90 3.6 C4 US spec I drove recently. They are both well sorted and maintained.

I have an 'earlier' S cam (I'm told by the tech that did the rebuild), SSI heat exchangers, Dansk exhaust, K and N filer and green Bilsteins at euro ride height.

Has anyone else had this type of experience? Is it a delusion?

Your time and expertise are appreciated.

Engine number?
Is it a cis system?

77
RoW: 90 mil bore X 70.5 mil stroke, 2.7, 8.5:1, CIS, 165 hp at 5800rpm, 176 flbs of torque at 4k

US: air pump , thermal reactors, and EGR
same specs as above

carrera and 930 had 3.0 200hp

Via Redbook

Sans emmisions crud and the s cam and exhaust upgrade you might have gained 20 or more hp. They are snappy and lightweight. I love my 2.7 middie.

Engine number is *6371222

Yes it's CIS

Appreciate your feedback......

The 2.7 cars are just significantly lighter. They used a lighter gauge steel so they rust more, but as long as they are looked after it's not problem. The engine and gearbox are lighter, the braking system doesn't have a booster, and I'm sure I'm missing some other things. They weigh stock under 2400lbs or thereabouts, that's what my 74 weighed in stock form before I started tearing it apart to restore. Because of this they are undoubtedly my favorite street 911s, especially the 2.7 MFI cars. For some reason 2.7 engines just rev better, much happier sounding engines.

I think my 77s was around 2800. it was a targa and had steel wide body flares and a tail.
I was told the 77 was a good/better year because it had the lighter steel but was galvanized, as the earlier cars were not.

I really liked the brakes in that car. the seals were not in great shape and the brakes were still extremely impressive. if I did not buckle in or brace myself I had a very bad domino effect in that the more I braked the more I slid forward thus pushing more on the brake and sliding more.

I'll dig into the Redbook as a resource. I thought I read somewhere that there was a compression difference 8.0: vs 8.5:1

I'd think there was a HP variance from the factory with all the emisssions stuff on US market cars.

Thanks for the feedback, I think you hit the nail on the head; snappy and light weight.

This is a targa and they were galvanized in 77, I'm going to a find a car/truck scale and get an exact weight. I think weight is a major factor here.

The brakes are sweet. I think they have great pedal feel and an ability to be very precise.

I think the steering is totally manual and believe there is no hydraulic assist on the clutch either. It's got a very simple, mechanical feel all the way around. My thought is that this simplicity results in the feel I prefer over the later Carrera and 964.

I'm dying for a little seat time in a ROW SC for comparison.

that's what makes the early cars so great.

lighter, "bare bones" with no frills. gives great feedback thru the steering.

been a very long time since I drove an early car or even my home built 914-6, but they were all different up through my 77 and now my 930.

the 914-6 was by far the most fun. would loved to have had better brakes though.
I had a 2.2e in it.

never driven a "newer" car. heard they just weren't the same as the older ones.
I did hear good things about the 993 though.

I bet a 914/6 is a hoot..... more fun than a 930, wow! I rode on a track called Nelsons Ledges in a four speed 930 when I was about 17/18 years old and it felt like the front tires were lifting off the ground when the driver was hard on the gas coming out of corners, unreal. One a few Porsche experiences that committed me to seeking out a 911 as soon as I landed a real job.

I just missed out on buying another 914-6 the other day. I have felt like crap since I saw it listed and it was sold. $16k. with GT flares.

914-6's are wonderful cars! I owned one for 18 years and it was my DD for six of those. Nothing I've had since has been so much fun. And with the two trunks practical as well. Nothing on today's market even comes close!
