Hi, my first post so hope I am in the right place, I am building a Ferrari 250 GTO replica ( http://www.ferrarispares.co.uk/250gto.build.html ) and want to use the Maserati 4200 engine and 3200 Gearbox, so is this possible and will I need a special adapter plate and if so who can make one, I was originally going to use the 4200 Transaxle and subframe but the track is way too wide so now I am thinking to use the 3200 g/box and also the rear diff and subframe and hopefully I will be able to narrow the subframe and shorten the drive shafts to suit my GTO, and help with parts and or advice much appreciated, Regards DM

I think you will be on your own with that one.
The 4200 never had a close coupled gearbox, just the transaxle layout.
However the wet sump version of the engine was fitted to the QP and GT with a close coupled auto gearbox.
Why not simply use the 3200 twin turbo engine with of course its manual gearbox?

Anything's possible, but like Mike says why not use an old 3200GT engine complete with its manual gearbox!

Bearing in mind though a proper 3200 engine rebuild would be around 8 to 10K as lots of the parts needed don't exist any longer or will need to be remanufactured..

Well worth it though ;)

Hi Thanks, main reason I want the 4200 is it is a proper Ferrari Engine and also not a fan of Turbos, Regards DM

Well just a thought but the 4200 uses a Ferrari 360 gearbox, does the 360 not have a narrower track?and could this not be optimized for you, especially if you change the hub centres on the wheels?

Hi Thanks, the 360 is a mid engine layout, and the GTO is front engine, Regards DM

I'm sorry but it doesn't. The internals are similar which is probably where this myth came from, but the packaging (which is the critical element in this case) is completely different.



360 rear track = 1617mm, 4200 = 1538mm

Hi Thanks, total width of the 4200 is 1822mm and my GTO is 1675mm which is even wider than to OE GTO, Regards DM

Despite looking similar, the 4200 and 3200 are mechanically completely different cars, so i believe that a combination is doable, but needs a lot of time to see how engine 4200 and gearbox 3200 will fit together. Good luck in the case you try it.

Hi Thanks again, I have been thinking maybe I can still use the 4200 Transaxle as I am no longer using the 4200 suspension and will be using the Ferrari 308 GTB suspension maybe I can still use the 4200 Transaxle ?? so can anyone tell me how wide it is accross the Driveshaft Flanges of the 4200 transaxle so I can work out how long my driveshafts will have to be, Regards DM

Hi, calling all Maserati 4200 experts, this is where I am now, I have just got a QP 4200 engine dry sump, and Torque Tube/Prop shaft and Combicorsa transaxle,

First major problem: I will need to chop the Torque Tube and Prop shaft by approx half its length, so has anyone done this or know who can do it ???

Second problem:I need to convert the Gearbox and clutch to manual operation, I have removed all the hydraulics etc from the Transaxle and looks like I can just get a a gearlever and cables which I will also need to shorten,?? is that correct ??,

Thirdly : the clutch, will I have to remove the auto mechanism and fit a manual slave cycl and master cycl and clutch pedal ??

That is enough for now, so any and all help will be much appreciated, Regards DM

Regarding the prop shaft, a prop shaft specialist may be able to help, gives these guys a call: http://www.propshafts-greno.co.uk/
Conversion to manual, get all the bits from a 4200 Manual car from a breaker.

Hi MJ, Thanks, I will give them a try, what I was asking is what will I have to change to convert to a manual clutch, is the Flywheel and clutch the same on Manual or Auto as it looks the same to me and only difference is the electron activation, so can I just fit a clutch master Cycl and pipe it to the OE slave cycl ?? againThanks, Regards DM

The Torque Tube is a delicate piece of kit might be easier to have a bespoke shaft made up.

Hi thanks, nothing delicate about the Maserati Torque tube, in fact it would look at home under a Lorry, but I am sure it would cost a lot more to have a complete new one made, Regards DM

Would it not be easier to sell the CC box and find a manual one?

Hi Catman, yes that was my first thought as well but just could not find one at the right price? and everyone told me the CC box was exactly the same and all I had to do was remove all the electro/Hydraulios ?? and fit the manual gearlever and cables ??, Regards DM

Treading carefully I think that's probably true, but I can imagine there might be some gotchas that might, well, get you. ;)

Given the scale of what you're trying to do, I can see you likely to succeed :)
