    Our silver 208 GTB turbo came home on may. Came from a very old doctor, a pleasant but very old man, that did not drive anymore the car since many years. It looks it was driven by Michael Schumacher too, in the past millennium. But this is not important: the important thing is that this car was unserviced since many but many years. The car was good, always gently driven, completely original, complete of everything, sound, no riust, but abandoned since many years. No problem: we got it at a fair price, so there is room for an expensive engine hoverhaul with a big major service with the engine out and a car general restore. I hate bad looking scraps that just once were a Ferrari and now they are shameless rust wreckages!

    I will post here, step by step, the resurrection of this gorgeous car: hope you like it, as for me is always a joy to see the reborn of a vintage Ferrari.

    Here below how the engine was after it came out of the car: a disappointing sad view...

    Thanks a lot for those rare pics.
    Amazing to see how the 3 liter bloc is downsized for becoming a 2 liter!
    Bore is 81 mm for the 3 liter and only 66.8 mm for the 2 liter while distance between the cylinder remains the same.

    Same stroke? So you could bore out the block and liners and have a 308 turbo ��

    I doubt the diameter of the combustion chamber in the heads is the same.

    Albert, What do the heads/combustion chambers look like?

    Why should I destroy one of the just 687 F106D 2 liters turbocharged engines built (note that this one is the No. 217) to have one of the many 3 liters? ;)



    I haven't seen it yet, as heads were sent to the machining shop before I could take a picture. I will take a picture and measure it when it will come back from the shop.

    I just learned this engine was produced on June 1982 (see the picture)

    ciao

    The funny question marks at the end of my post are a smiley face that did not come through :). Clearly much more work would be required than what I suggested and you are right that it is more valuable as it is.

    Thanks, Furio. I will keep you all posted.

    Yes, you could and It wouldn't be difficult.

    they look like the 308 2 valves ones, but smaller. Heads are the same of the three liters (like all the engine), but they are less machined with smaller combustion chambers, smaller ports, smaller ducts. This is what my mechanic told me: I haven't seen nor measured them yet: I will do it as soon as they will come back from the machining shop.

    ciao

    Looking great. I know it's been discussed before, but what is the primary difference between the 3.0 and 2.0 V8s?

    And from the outside, no one would even know.

    The question is, could the OEM Turbo actually "boost" a 3.0 Ltr motor?

    As I understand it, the same "main bits" are identical to both motors.

    Only the internals are different.

    True, Pros?

    Yes, it's a big KKK k26. It's even too big for just a two liter.

    Yes, they did. It's a stroker engine: 66.8 x74 mm instead of 81x74 mm. Same crankshaft.
    It's the smallest V8 car engine ever.

    Yes, it is. But many internals are the same too.

    So making a 3.0 Turbo from a 2.0 Turbo would be pretty easy, viable, and no one would even know.

    Talk about a sandbagger ....

    I think the best way is to keep it as is, maybe overbore a bit, but not much more: those cars are so rare that I think they deserve to be preserved

    I like that you are leaving the 2L alone. It will never be a 360 motor. 2L turbo is cool, original, and different. I thought about a 3.4 for my GTB and decided against it.

    Agree: I think that if you aren't satisfied with the power your car has, maybe you had better buy another one rather than modify your one with a diffrent engine. An F430 costs less than a 328 ad much less than a drysump, today: If you need power, buy an F430, or a 350 c.i. Corvette (that is MUCH cheaper), but please do not rape old italian beauties.

    Those cars are pieces of history, and so, they should remain as much original as possible forever, in my opinion.

    100% agree !


    btw. could you please tell me the bore (new) and the supplier of the new pistons, because the twin of your wife's silver GTB will also get a engine overhaul next year.
