Mods on my little Punto T-Jet
 

I did not write on here for a long time, I changed a few cars and thought I could write about the mods I did to my latest, a little Fiat.

It is a Fiat Grande Punto 1.4 T-jet 2009.
I bought the car with LPG install already done. Since it's a clean fuel and half the price of gasoline it makes the car pretty Eco friendly..
The 120 HP it has factory is nice but not enough given the fact that it's called a Sporting.. So came the need for modding :)
The 17 inch Abarth wheels with wide low profile tires it came with were very nice but made the ride comfort bone shaking. So I changed to 16 inch with a narrower tire size. This gave me around 0,5 litre/100km better fuel economy and less harshness on potholes. :thumbup:
I wanted more power since the car wasn't fast enough given the still sporty looks, so I got it remapped. Now it had good torque like a diesel but was choked in the higher rpm range. Even better the city fuel usage became less dropped from 9,6l/100km to 9,1l. Highway economy stayed around the same 7,5l/km.
Then I realized that my 5th gear was too short..(sadly no 6 speed box in the sporting). So I searched around an find out the Diesel has the same box with longer gears. I managed to find a set and changed them. This dropped the highway economy to 6,9l/100km.
The stock turbo is really small even by European standards so I changed it to the Abarth Grande Punto's witch has a bit bigger compressor. The turbine housing was cracked so i bought a Chinese housing but I did not like the rough surfaces so did some work to it. This costed some low end torque but actually caused better city economy because boost onset is later in the rpm range.
Another mod I done is not economy related. I changed how the electric power steering reacts. It was over doing the helping when I turned the wheel suddenly but a small amount. So i have put a small circuit inline with the sensors under the wheel. Now I can modulate it with a pot.

Subotica looks like a nice place. I like Art Nouveau.

The Punto is pretty sweet. According to Wikipedia is was designed by Giugiaro. Do you have the three-door or five-door model?

It is a nice place. A lot of buildings from the end of 19th and start of the 20th century in Secession art style.
They call it a mini Maseratti :p
It's a 3 door, I kinda like those more in a small hatchback..

:thumbup: 4-door driver's doors are too short for my ...needs.

My Dasher was designed by Giurgiaro.

I consider that a mid-size.

Well the Punto is 4 meters long but has suprisingly little space in it.. There is no boot basically.. :(

Wikipedia says 3,760 mm (148.0 in), same as the XFi. The slant-back Dasher can't compare with the VW Squareback.

Do you have further plans?

Is the 120hp version fitted with the 8-valve cylinder head?

Basically like the 1.4 Multiair engine minus the multiair system.. :)
It, has the same 16v head as other non turbo FIRE 16v engines.

So it's basically the same engine fitted to a similar version in my country, yet it was the 150hp version. IIRC the 120hp version was also fitted to CNG-capable versions of the Doblò and the Bravo in Italy and Germany.


The only application for the 16-valve 1.4 without a turbo in Brazil was the 500 while it was still sourced from Poland instead of Mexico and switched to the 8-valve.

Most cars in my country are from import. This car is from Italy. It was availaible there with the 1.4 8v 75HP; 1.4 16v 95 HP; 1.4 16v turbo 120HP among a few orhers.
The Abarth version has the same engine with bigger cams and turbo. That is the 155HP version of the T-jet.
That same engine is in the Nuova Bravo 150 HP i guess that is the version You speak about.

I used to think Fiat assembled the Punto there in Serbia, as it did with the previous generation. IIRC Serbian Puntos were sold in Chile.

The Punto II was assembled in serbia. The factory was then retooled for the 500X.
The Melfi factory in Italy produced the Grande Punto for the European markets I think.

Well for efficiency there is a piggyback device witch can alter spark timing on LPG since it burns differently to gasoline. That could shave a whole L/100km from the consumption on gas.
I am still a bit afraid as it is a high strung little turbo engine, so it is easy to melt a piston or two :eek: if things do not work out as intended + mine is remapped for more power..

Another area I will look into the summer is weight.. But I could use some advice on that.. :confused:

Spare tire delete.

I don't have a spare wheel, I have a nasty donut shaped pressure tank for the gaseous fuel in its place. So that is even more weight which i can't remove. :(

IIRC the 500X and the Jeep Renegade are made in Melfi, while the 500L minivan is made in Serbia.

Yes, my bad. The 500L is made here, in the same factory where the Fiat 128 clones were made during socialism. :)

I have never seen a 500L, but the 500X being available in neighboring countries such as Argentina and Uruguay renders it not so unlikely to be seen on a beach on summertime. When it comes to older Fiat clones made in Serbia, I was more aware of the 127 clones.

These are the cars the Crvena Zastava factory made, and were directly based on the Fiat 128

https://en.m.wikipedia.org/wiki/Zastava_Skala

In 1979 they started production of a Bertone designed model under a new brand name: Yugo. The concept, size and category basically were copied from the Fiat 127.
The drivetrain was similar to the 128 clones except for the weakest model the Yugo 45 this used the Fiat 100 engine in 903 ccm form.

The business model of some Fiat licensees and even fully-owned overseas branches is quite interesting. There were times when the Argentinian operation was not fully owned by Fiat, and the 147 which is a regional derivative of the 127 had 124-based engines in Brazil and 128-based ones in Argentina, and at least in Uruguay some versions locally asembled from CKD kits resorted to the 903cc engine. Well, considering other Fiat models assembled from CKD kits had some parts supplied by Zastava, who knows if a Serbian-made engine had ever fitted an Uruguayan 147...

Yes, really interesting.
It is easily plausible that there are DMB manufactured engines somewhere among those.
The drivetrains for the Zastava and Yugo cars+ crate engines for Fiat; parts for Lamborghini tractors; the Turbomeca Palas gas turbine engines were all manufactured in a separate factory called DMB
