Technical 1.4t jet grande punto 2009

[grumpysi]

Got to replace engine t belt went.looking at second hand engines is there any difference between punto and bravo engines or what else to look for. Or any recommendations or extra info cheers

120 bhp should be the same, worth checking eper though as the cars use different transmissions.

Cheers

Bravo T Jet is 150 bhp. Not sure if it would work? FiatGrandePuntoEvo spares in Wales recently had a low mileage Punto- T- Jet engine for sale 40,000 miles, 01559 363 313

Bravo T-Jet comes as 120 and 150 bhp with the latter having different cams and turbo, same engine as abarth. 120 bhp bravo engine is identical to GP T-Jet engine.
150 bhp would also work but you'd need a map to account for higher lift cams and turbo.

If you put a vl36 on a t-jet 120 you get the same power output as you would in a 150 so the only difference is the turbo unless someone has part numbers and specifications that can prove different.

Grande Punto and Bravo have same engines. Here is technical data.

Surely you do not mean just the turbo change, ECU needs mapping too, no? And they do have different cams.

Looking at the data the inlet cam is 0.05mm larger in the 150 and 0.04mm larger in the outlet cam so they are different but not alot. 120s have run 150bhp+ with a vl36 before any remap so we are probably only talking a couple of extra bhp post turbo swap from the slightly higher lift cams.

The 120tjet + VL36 feels like **** (without a tune).
I've done it, the hp measured on a dyno is close to 150 hp... but the power curve is really bad, power falls down greatly after 4500rpm

There is something more to the cams and tune, in addition to the lift there might be some more duration, or maybe the injection timing is slightly different.

 

[mattfred]

Cam timing is different too.
