I think a proper tune would not pop and bang, being more efficient.I have no pops and bangs. Would love some flames as well.
Put UT internals
One question I would ask is if installing the UT internals will make the shifts any faster? Are they that much different design that it will shift better - or did you mean something else by that (sorry if I misunderstood)?I would like to be able shift gears faster
Changing the final drive ratio should have an effect on how quickly you can go through the gears. But I think you will need a lower ratio (shorter, not taller gears) to achieve that. And then it will be revving even higher (not less) when cruising on faster speed roads.I want to get engine’s rpm lower, a lot
If the later trans after UT (C510 I think?) is much better and it is a different design, then it might allow faster shifts and be stronger to hold the added power (torque) from your turbo engines. That may be a better answer as Bjorn is thinking.look for absolutely other gearbox that could fit X19
Happy Birthday!!I I start to feel old when remember all the times when have greeted myself on birthday here
Happy birthday to me again!
Yes, these pics needed filter
Will add finger savers after a moment and someday add “Boomerang” on the right spoke
I imagine someone somewhere at some time has figured out a cable shift arrangement for the C510. I guess the question is who?But unfortunately, building a cable mechanism is more complicated
The C510 in UT Mk2 is not cable operated, it has a rather complex link system. But to work in an X it seems to be easier to convert it to cables. I know that MR2 cables and shifters works quite well. A system from a Fiat Doblo also works. My biggest problem is that my gearbox is missing mounts for clutch hydraulic (red plate in pic) and the "up/down" mechanism on the gear selector.I imagine someone somewhere at some time has figured out a cable shift arrangement for the C510.

Can the stock shifting mechanism from the original car that a C510 came from be modified to work?
I did not know that (we never got those cars here). So I see what you mean now.The C510 in UT Mk2 is not cable operated

I've looked for missing parts but they are hard to find.
The late C510 6 speed does not fit on the UT or X engines. The starter is on opposite side. There are probably other differences as well.Hi Bjorn,
I find it very interesting that the C510 gearbox is as close a relative to the standard X1/9 gearbox as the photos above indicate. When you consider that the C510 is used right up to roday in the 500X with even 6 speed applications then I think that there are quite some possibilities in this area (see: http://www.fiat500usa.com/2009/09/fiat-500-transmissions-5-or-6-speed.html). Moreover, it kind of explodes the popular myth that the X1/9 gearbox is inherently flawed: clearly it was simply evolved in more modern Fiats to handle in excess of 200 Nm of torque.
If you are going to the effort of swapping in a C510, why not opt for one of the most recent 6 speed variants?
Cheers,
Dom.
