Grande Punto T-Jet 120HP @GT2056

Hey guys,

my name Nils writing from Germany. So I'm sorry that I can't write in Greek :-(
I'm going to introduce my car which is going to be revlimited in next few days.

The base was a 2007 Fiat Grande Punto 1.4 T-Jet with 120HP.

At first I changed the exhaust system to a Ragazzon catback system.

With the time the car seems to get very slow :-))) so I wanted to get some more power.
I had a Garrett GT2056 at first, but now I am going to run the GT2871 (now sold), but it is journal bearing not ball bearing like a Garrett turbocharger. It has also a reinforced clutch. A manifold with bigger in- and outlet, esseesse map sensor, 73mm forged pistons, sparks with a heat rating of 11, carbon airbox, 380ccm S3 1.8T injectors APY and a blowoff.
The GT2056 with standard pistons

The GT2056 with CPS 72,4mm forged pistons


The old GT2056:

And now the new GT2871 with the new 73mm forged pistons:



The car will be ready in about 2 weeks...I hope everything will work fine.
Soon I will add:
-valvetrain
-camshafts
-rods
-another turbocharger

I hope you'd enjoy :-)

very nice photos Nils

Stay tuned...

This week the car will be relaunched with the new setup :-)

I'm going to get some nice pictures and up them here...

I can't wait for your photos...

Here are some pictures 'till the car will be launched...I thought it will be this weekend :-/ But it's a mission impossible :-(
The engine:

And in the car:


Fotis made a map for the first 1.500 klm of levelling...then the software will be changed
I can't wait to get on the road

nice pics

I will be back on track...soon! :-)

Niceeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee


lets see me with 2860rs ..............................

That would be very nice :-) Please go ahead with some pictures!

I've bad news :-(
The turbocharger was blown during the test period and now I am going to buy a new one.
It was the fault of the mechanic he didn't connect the cooling for the turbocharger and so that the turbocharger overheated.

But Revlimit did a good work. He had no fault on the damaged turbocharger!

I think, you need a new better mechanic

I've taken my car and get it home...on a trailer.
I put the old GT2056 on it to perform some test runs (no driving; just till the other turbocharger will return).
The engine runs very smooth but at the moment it has no exhaust just a catalyst it's very noisy;-)



The rest will follow...

I got some news today...
The GT2871 is on the way back to me.
It will be installed soon.

That's nice! We are waiting to see it installed!

I need to update something here.

The GT2871 was sold because of the bad compressor map for the T-Jet engine. It would have been power at approx 4-5k rpm.
So I kept the GT2056 for a while and gonna install the GT28RS in the end of the season.
But the exhaust system is also modified. Only a 100 cell catalyst in the midpipe and no silencer remains to kill the power.
Revlimit is gonna perform a perfect map for the GT2056.

GT28RS is a great choice for T-Jet which like to rev up to 7500 and boost till 1.7-1.8bar! It's a little bit laggy (4000RPM full boost) but this turbo is a perfection at high revs.

You will be impressed, believe me. BUT, you need a correct pair of camshafts to turn to account all the benefits of the large turbine housing and high reving and of course a reliable high reving!

I forgot to update here ;-)

I gotta thank Revlimit for the great mapping. The engine is running pretty cool.

Updates:
-Revlimit mapping for boostcotrolling -> atm 1.4bar constant boost
-AEM Uego broadband installed
-New supersprint exhaust system installed (incl. bypass cutout before catalyst with remote control)
-GReddy profec b spec II installed
-backseats removed, abarth frontseats

Coming up next:
-camshafts
-rods
-valvetrain
-GT28RS

With rods + vavletrain + 28RS, the party will begin
