    Yes. I was commenting on how the chassis can be expected to look so much better in silver, as judged by the bare metal photo. A silver body would be nice too but this car has been determined to keep its redness.

    Correcto. Red she will remain. The car raced in red and there were no race LM's in silver, black or white. That would, to me, detract from its history and make it more of a road car.

    Tim now that the mere idea of silver, black or white for the F40 exterior color has been swept aside... will you be using the modern Rosso Corsa base coat/clear coat paint process?

    Thank you for sharing your F40 project here!

    OK, well here is the gearbox all stripped down and unfortunately reverse has developed evidence of heat cracking on the synchro ring. As I mentioned earlier, $15k from Ferrari as that includes first gear and the shaft but we are lucky in the UK to have one of the world's top restoration companies, Crosthwaite and Gardiner, who, if you can credit it, have recently completed manufacturing, from scratch, an Auto Union D type for Audi complete with V16 as well as a pair of Mercedes W125's. Check out their website Crosthwaite & Gardiner Fascinating. Consequently reverse gear, I suspect of a rather higher quality than factory, for my little effort should pose few issues. I think we will also be coming back to them for some further engine work but more about that later.

    In these images welcome to the workings of the F40 gearbox and as I said we are taking the precaution of replacing second gear as that was a weak spot especially with all the extra power.

    The other picture is off the LSD which was not working properly so we have stripped it down to find the friction plates are worn and useless. Ferrari don't offer friction plates as replacement parts and prefer you to buy an entire diff so we are examining our options.

    Is this too much detail?

    Hi Tim,

    The answer to your question, is no. The level of detail is absolutely spot on, and this is my current 'must read' thread.

    Really appreciate you sharing these stages of the rebuild, warts and all, it gives a fantastic insight into the ownership of my ultimate supercar :).

    PS, sad i know, but yes I have registered to the forum just to view this thread ;)

    Thanks.

    Pete

    No such thing as "too much" in regards to detail. Details are what make the car. Awesome project, and thanks for sharing this with us.

    Would really appreciate some input from anyone who knows about these cars.

    The current turbo arrangement is 23 years old and is a pair of KKK's with twin wastegates and that is how it raced, unspectacularly. I want to upgrade the turbos and we could go:

    1. original LM but then they are old turbos in design terms and have a tendency to overheat apparently but strong historical link

    2. Garrett turbos. They make a perfect modern roller bearing highly efficient turbo and I think we're used in the GTE

    3. Any other option? Modern IHI's if available and suitable

    I have to have an eye on the cars history even though we are effectively just continuing its evolution, and so need to use a manufacturer that the car did use. We will keep the twin wastegates regardless.

    Any qualified opinions would be great.

    Have you tried Cristiano Michelotto, Tim? They have the LM turbos if you're to be tracking exclusively ("not a good result" for the street) - as well as the current street replacement (sometimes referred to as "LM" in the U.S.).

    re: "heat cracking," are you sure? I am surprised that the temperature could be high enough to cause a crack unless it was under considerable stress or defective. Do you recall any unusual noises or balkiness in the forward gears when you drove it after it reached operating temps? I think you want to rule out some kind of misalignment in the assembly.

    I am enjoying learning about this car.

    Personally, I would go with the most modern option available to you. Turbo technology has improved A LOT since the F40's debut. Turbo lag can be significantly reduced while making more power. Durability has also improved.

    If performance, drive-ability, and durability are more important to you than originality, go with the modern turbos.

    That is the nub of the problem. Driveability versus originality versus value! Somewhere in the middle is an answer.

    Tim you could go with a ceramic ball bearing turbo as they supposedly decease spool time significantly but the cost is also significantly more. Also you could go with a more aggressive turbine and compressor, just a thought. Or there is the possibility you can have the original turbos rebuilt installing the suggestions I made.

    Yes, I am speaking with him at present but my issue is that whilst the car will be used mostly on track, having it drivable on the road is an added bonus. Am considering going the Garrett route as I can get support here, albeit I like the idea of IHI but no support. The answer may be to go Garrett and keep some LM turbos on the shelf for the hopefully, long distant day of sale?

    Beautiful. Too bad they will not be visible, as well as "bulletproof."

    Well here is the trail from what they were to what they are. Perfect. In fact so good I would like perspex wheel arches or a clear panel in the wing!

    Strong, light, durable and to me, a work of art. What's not to like? It also gives a good idea to you of the standard I am trying to attain with the rest of the project but a very long way to go.....

    So these now go into storage for a few months. Quite a few......as you will learn shortly

    Yes. Industrial art.

    And this does set the standard for the rest of the project. The first thing you do in a project has that effect.

    Beautifully done. The bits of yellow in the weave make it look pretty cool!
