It is possible to use a Quattro gearbox in your proposed installation, however, you need to blank off the rear output shaft. I know that this is what Spyker did for their US cars to piggyback them into the US based on the Audi A8 emissions certification. Personally I am not a fan of this approach as it puts the gearbox under unplanned stress.

It's not advised. To "convert" the quattro 01E to 2wd you weld up the centre diff. That however doesn't make it equivalent to the 2wd 01E as the hollow input shaft of the quattro is not as strong as the solid one on the 2wd. After all it's only designed to take half the torque. It's also sticks the engine *way* higher than the G50 (or UN1, although that's not as "strong") and isn't invertible like the UN1 and G50.

Anyway my advice is go with what everyone else does. LS and gearbox of choice. I say this as someone who has gone off the beaten track and the trouble is that while you might find the engine cheap the additional costs and grief ramp up. An LS engine with a transaxle in a mid-engined RWD car is a solved problem. You can buy it off the shelf. You have people with experience with doing it.

Trying to get for example a modern FSI Audi working with an autobox and you are looking at a world of hurt and a mass of costs.

Syvecs have ecu's that will operate both the engine and trans no problem, although that's when integrated into the car itself. No doubt it could be applied to a conversion too.

But yes all of that would take money, but certainly it's very doable. Whether it's worth that effort or not is another matter. Cheap and simple it aint.

which semi auto trans with paddle shift mode can fit on an LS engine?
and on which LS engine?

Exactly. Totally doable but £2.5k minimum just for the ECU (the lowest model that does GDI and it still needs an add-on extra unit for the GDI which I don't imagine is free) and *then* you have to get it running/tuned.

Or you buy a new turnkey LS which has everything from £5k (first example I found, probably not the cheapest and have to add shipping, import duty etc on top).

I have no idea how the semi-auto's connect input shaft to the engine (flexplate?) as I have zero interest in such things but as far as physically mating a transaxle gearbox to the engine

Pretty much any of the Audi ones (016, 01X, 01E etc)
Any of the Porsche ones (G50 etc)
Any of the LS engines.

what about the engine of Pagani Zonda?
As far as I know, Zonda was using the engine of the Mercendes-Benz V12 S600
I think is the W120 edition but Im not sure....
and in the begining,
the cars were manual and afterword they were DCT....
does anyone knows, which tranny they are using?
for the manual or the DCT ?

So...from a cheap simple LS....to a Pagani Zonda engine ?

Then from a manual to an auto and maybe back to a manual again ?

So is the engine/drivetrain to be a £5k build...10k build...50k build...100k build ?

Yes, unfortunatelly I haven't decited yet, if the kit car Im gonna build,
it's gonna be manual or a recent model that has DCT or semi-auto tranny....

By the way, the S600 engine we can purchase it with a couple of thousand of euros from e-bay.....
it's not very expensive, that's why Im intresting on that....

I would chose your kit car first - once you know what you are building the kit manufacturer will tell you which engines they have mounting kits for and which gearboxes to use. You can then price up doing it this way as well as doing it your way with your preferred engine and transmissions.

If I was doing what you are doing I would use a LS crate engine as most kit manufacturers and also independents have loads of experience with them, have fitted them to everything from Minis to boats and there is a lot of choice regarding transmissions.

If you want 500+bhp a semi automatic gearbox for a mid engine car is going to be the most expensive part of the project. If it was front engine/rwd its much more doable for realistic money.

Engine wise i have used BMW V12 and BMW V10... the V10 is most powerful although more expensive.... the Merc V12's are huge units, good luck fitting that in an engine bay meant for a KS V8.

If you go LS route you are going to spend £5-10k+ on the engine for 550bhp, £5k on the gearbox/clutch/adapter for a manual (loads more for semi auto).

BMW V10 for similar power you are going to spend similar money for similar power for a second hand unit... same money on the gearbox etc.

In reality you need to decide on budget as that will dictate your options... if you say you have £5-10k for engine and box then you are talking Audi V8, SBC etc with a manual.... if you are spending £10-20K you can stretch to an LS or BMW V10 (or audi V10) etc with a manual.... if your budget is £20-100k then you can go for more exotic engines with semi auto boxes.

BTW don't forget in almost all cases you need an ecu etc to run the engine, thats a significant cost especially on the more exotic V10/V12's
