Boxer Evolution

Hi........

Just saw a post at FerrariChat about the locations of the radiator fans on the 512 Boxers. The ones with carburetors have fans in front of the radiator and the cars with fuel injection have fans behind the radiator ?!

During the evolution of the Boxer from 365 to 512 to 512i, how many differences were introduced by the factory, aside from the obvious ones, such as engine displacement, fuel delivery systems, taillight number and aerodynamic "tweaks" ??

Frank,

loads of little things...the tool kits were changed, the way the glove boxes opened, the interior dome lights assembly, the front grills, the front fog lights, the wheels & tires, that's all I can think of at the moment...

Rembered another change/update...between the 365 & 512 the Limted Slip Diff Housing and R&P where both changed.

Of course they went from cable clutch to hydraulic also from the 365 - 512.

Hi......

Thank you for the information. Hope to document all of these differences at the Boxer Website. Will ask members of the register with cars made in different years to provide photographs of front, side and rear views, and interiors as well. Would be nice to be able to identify the year of production and type of Boxer by a quick exterior evaluation, without peeking at the insignia on the rear deck or asking for a serial number.

Hi....

The attachment contains a summary of considerations for a Boxer purchase. Hope it might be of some use to anyone in the market for one.

Hi Frank,

You need to inspect the long front headers very carefully as well. Mine were rusted through and badly cracked. Complete exhaust on the 512BB is pretty expensive.

Carbs last about 40,000 miles and then have to be rebuilt at about $700 each.

In your document you also mention inspecting all of the rubber hoses. I would add that if the inspection determines that they are original then they should be replaced as soon as possible. Particulary anything rubber that has anything to do with fuel.

Since I am now driving an almost brand new Boxer I can't emphasize enough the need for a professional inspection.

Good points Grant...

While we're on the subject of rubber hoses...

Often overlooked, and not relating to fuel are the rubber brake hoses. About 10 years ago, I had a slight pull under moderate braking. Although the pads,rotors and calipers appeared to be in good mechanical and visual condition, I couldn't get much brake fluid to flow out of the brake bleeders on one of the front calipers...

Diagnosis: The brake hoses looked great on the outside, but when cut open...were 80% restricted due to deterioration.

New hydraulic hoses, all the way around...and no more pull.

Frank &amp; All,

Frank, thanks for posting the helpful, comprehensive list. Anyone purchasing one of these cars should certianly print that out and study/follow it.

On the rubber brake hose issue.

The internals Atrophy and eventially pinch off fluid transfer. Even though the outsides may look fine, the insides degrade over time. I am of the opinion that these hoses should be replaced every 15 yrs (max). Like David mentioned Pulling is a very common problem associated with bad flex hoses.

Many of the Ferrari hoses are the same as other Euro cars in manufacturer, lenght, spec &amp; design, and can be readily found.
