Hello,
We're facing a rather annoying problem with my dad's Fiat Multipla, model 2005. It is using the 1.9 JTD (115Bhp, 205Nm torque) engine.
After chiptuning ( 140Bhp, 270Nm torque ), the clutch is slipping ( weak clutch spring ) and juddering ( weak springs in the 2 mass flywheel ). Is it possible to change the clutch and flywheel by the ones used in alfas ( 147 / 156 ), or are there any other solutions?
( downtuning is not quite an option

)
I've heard the clutches are interchangable, but I've only read about this once and I need a bit more certainty
Thanks in advance!!
