The 2.4 is a 5 cylinder, so only 10 or 20v

I've no idea, I know a lot of people run a remap on the 2.4 20v with up to 250/260hp, the 1.9 16v can achieve around the 200hp mark after that you need to look at different turbos, intercoolers and other bits.

Garage
here by us (Hungary) was made a Grande Punto with JTDm 16v engine last week
360HP at 4600rpms and 602Nm at 3900rpms at 2.5bar boost (~350kPa), with regular diesel fuel, no WMI, no NOS
and it produces 330HP between ~3800rpms to ~5600rpms, at 5600rpms is now the limiter too
little grey smoke only from exhaust, but was mapped only once, accerelation from 100kmh to 200kmh is around low 9seconds
not yet finalized, needs some fineing in ECU map
but... wooooooow

dont know the CR pump and the turbo and injectors exactly, just saw the RR measure diagram from it on friday

owned had further (last year) a mk2A Punto JTD with 1.9 8v engine, it ran on 1/4mile 13.1sec with no smoke
it was this car (but now is sold):
