Hello, I was wondering what are differences between the 365GT4/BB, the 512BB and the 512BBi, could any of you BB owners post a pic of the interiors of your car? What radio/cassette was originally offered on the 365 and the 512 carbs? Thanks CM
The main difference was the wheelbase witch was increased for the 512 series, also the power was increased periodicaly, 512BB had carbs whereas the 512BBI was injected. Here are some photos of the 365 GTBB.
I believe power was Decreased periodically. from 380hp in the 365 to 360hp in the carb 512 to 340hp in the Bbi.
The 365 GT4BB is the one to have imo. Its lighter and has more hp. Sounds better too. Plus the six tail lights/six exhaust tips combination looks amazing.
Since there were not any Boxers imported into the North American market, all are 'grey market cars' and required federalization to be legal. There was more than one vendor that did this, so you may see some variation car to car as different companies 'federalized' each car. Not only variations in, say, bumpers and lighting, but different actual engine outputs as different companies tuned the cars differently to meet EPA smog requirements. Add to this that once the DOT/EPA papers were signed, some owners then retro-fitted European equipment, many American Boxers vary car to car.
The main changes were from the 365 to the 512BB Enlarged motor Dry sump added Front spoiler to compensate for 1" of front end lift on the 365 at speed twin disc clutch needed for added torque of the 512 and easier pedal effort added cooling slots in the rear decklid for improved cooling NACA ducts in the rear for brake cooling rear suspension mod for less squat on accelleration 9" rear wheels vs 7.5" added wider track and slightly wider rear fenders 4 rear lamps vs 6 365 had power windows and a/c as a option vs standard on the 512 so the listed weights were 2724 365 and 3084 512BB. The BBi added 2 separarate fuel injection units and metric rims/tires and added additional weight from it, the bbi had a lower torque curve, it also had the Pioneer equalizer and deck. Ferrari had planned on only making a limited run of 25 Boxers then it went to 50 then 200 until the total of 387 365s, they then continued production of 929 512BBs and over a 1000 bbis
Anybody know what type of whells the black boxer has in the above pictures? They are aftermarket and dont appear to big
Hi............ Atheyg provides a great description of the differences between the Boxer "generations", except for the vehicle weights. Ferrari workshop manual claims "dry weights" of 2,717 pounds for the 365 cars and 3,330 pounds for the 512 cars. Water, oil and gasoline add many pounds to these figures. Road and Track magazine lists the "curb weight" of a 512 Boxer with EPA smog devices at 3615 pounds. Check www.masiarz.net/bb_resource for information on production numbers through the years. Black Boxer may carry Kinesis wheels. Check the Kinesis Website. Frank.........23005
When it came time to revamp the 365 GTB/4 BB in 1977, it wasn't performance but comfort that got more attention. Displacement was brought up to nearly 5-liters (301 cubic inches) through judicious boring and stroking, and the compression ratio was bumped up a bit, but more onerous exhaust emissions and noise standards ate up most of the potential power gains. Ferrari again listed the peak horsepower at 360, though the peak occurred yet lower on the tach. Dubbed the 512 BB, the revised car was somewhat easier to drive and live with, while producing very similar acceleration and top speed numbers. There was also a special produced on the 512 chassis. There was also a few spyder versions converted from the original.
Wow! I didn't expect 12 replies in few hours!! I find more attractive the 365, (the rear gorgeus) and IIRC she revs 500rpm more than the 512. However, the BBi interiors look better and less spartan. (probably just because the i have the radio and eq...) What is the difference in terms of handlings and brakes? I bet there's a huge difference from a 1974 365 and a 1984 BBi. Thanks CM
this is a great thread!!! i am drooling. i want a 365. make take awhile. but so did the 308 anyone know if the wider, 512bbi wheels will fit on a 365. seems there are a few things that can be done to a 365 to make it more friendly in traffic. nice pics !!!
The red/back looks like a 365 with 9" 512 rears but it may be a 512 that had an accident and has a 365 valance. All Boxers are great, good luck on a 365 their are probably less than 20 in the US, the 512BB has less than 50 with about 200BBis, this from a Forza article. Maybe Gerald R from the FML knows the numbers more accurately.
All the Boxers were great cars, but the original 365 was the bad-ass of the bunch. I had a very early one, engine number 014, and it was unbelievably fast. It did suffer some driveability issues, with only two cooling fans, it would overheat in stop and go traffic, but open her up on the road... and hang on. Hit an indicated 189 mph once, and although that may have been an optimistic speedo, it was the fastest car I've ever owned.
Hi, I have an older V-12 and have always liked the 365 BB. As the car is now over 25 years old, are there any import restrictions to bringing one to the US? Thanks, Art S.
To my understanding, there are no restrictions (DOT, EPA) on importing a 25-year or older car into the US. There is an import duty of 2.5%, I believe, and you will have to comply with whatever state emission requirements apply. This information is based on the research I did in 2000 (which included discussions with Dick Merritt at the US DOT) when I was considering importing a 365BB. I ended up buying a 365BB in the US. It's a fantastic car and I can't see ever selling mine.
here are some pics of my 84 bb512i, the interior shot shows the original pioneer head unit and graphic.
The BB512i is the best of the bunch; it has more torque, faster acceleration, is more reliable and an all around better car. The carbed Boxers do sound better, but have other problems that caused me to pick the BBi over them. The BB512 does have a higher top speed I believe. But, here in the colonies acceleration is much more important than top speed.
Everything seconded, except I don't live in the colonies and acceleration is still more important than top speed ! Have to disagree slightly on the 512BB sounding better, (in standard trim)...Maybe, but with a Sport System the BBi wins again - But then again, I am biased. Seb
I saw the link to the site with the boxer info, but is there a serial number registry? I am trying to find some history on 43723, an 83 512 BBi thx luke
