(T) G/Punto 1.4 Sporting Needs 3rd Gearbox - Opinions Please!

seems like someone likes to use there gearbox

Well it will have to be wont it. Needs to deal with something called torque and the ratios will be completely different.

Doesnt the Abarth share the box from the 1.9 diesels, when I drove one I seem to remember reverse being in the "diesel" position?

Its just a shame these things have to happen, I havent ever owned a car that hasnt suffered from some particular "common problems" they all have but these do seem to have rather alot of them.

Just because it has a lift up reverse it doesnt mean its the same box.

Must admit, never had gearbox problem on a GP before.

Just normally 1.2s that blow because of chavs sticking cheap heavy 17's on them and wheel spinning everywhere.

the petrol box has reverse right and down, the diesel left and up so I think it is a different box on the more powerful ones and I think the Abarth shares the diesel one.

Obviously its different. Thats whats Matt is saying...

Yes my point is that the Abarth with 180 ish bhp or whatever it is uses a box from the diesel as even the tougher 5spd one from the tjet may not be enough, the problem I have with it all is why have so many different ones for different power outputs and engine types, if they have tougher ones why not just use them on all the cars?

Gone are the days of 1 or 2 gearboxes with different gearsets capable of taking the full range of 65bhp to 180bhp....silly

The SS doesnt use a box from a derv. Do you realise how fcuked up the ratios would be? The SS uses the same box as a normal abarth. The reason it doesnt use a Tjet box is because again the ratios are different. You could stick a Tjet box on an abarth if you wanted just when crusing in 5th you would be sitting at over 3000rpm @ 70mph.

Its not the actual gearbox that governs that its the ratios within it surely!

For example Ford only ever used the IB5 box on the MK3 fiesta 5spd, yet that had outputs of about 50bhp petrols, through Diesels, upto RS turbos or whatever the really fast ones were, all the same box, just different ratios.

I think I have enough understanding of how cars work to know about gear ratios between petrols and diesels thankyou!

Maybe I should have said basic gearbox structure minus gearset to make myself clearer

How much power/torque could the T-jet gearbox take? would it need to be strengthend in order to take say 200hp?

Dont know anyone who has gone that far on a Tjet to find out. The easiest thing to do would be to stick the 6spd box out the abarth in.

Depending on the engine type, the vehicle may be equipped with the following gearboxes:

- 1.2 8v and 1.4 8v C514 - 5 speed gearbox

- 1.4 16v C514 6-speed gearbox

- 1.4 16v TJet 120 CV C510 - 5 speed gearbox

- 1.3 JTD 75bhp C510 - 5 speed gearbox

- 1.3 JTD 90 bhp M20 - 6 speed gearbox or C510 - 5 speed gearbox

- 1.6 JTD and 1.9 JTD M32 - 6 speed gearbox.

- Abarth - M32 6 speed gearbox

Cool thanks for clearing that up!

So what we are seeing is that the OPs gearbox is a 6spd version of the gearboxes that are known to sometimes give issues in the 1.2s with 17s etc on them. Well the Sporting comes with (heavy) 17s as standard, so with more power its fair to assume that they may be more prone to damage as I cant imagine the final drive/driveshafts etc are all that much beefier let alone the actual gears.
