I currently own a 2013 Fiat 500 Abarth which has the same motor in the Renegade.... I do NOT like this engine. It has a nasty power dip/ pause at about 3K under medium hard to hard acceleration. I have tried different power modules, intakes, and intercoolers to try to get it to smooth out. It has also a hesitation when starting out from a standstill and it absolutely hates heat. It's power deliver is never smooth or consistent.

The way Fiat designed it's intercooler piping is something of a joke. For instance, on the flex piping, you will have a worm clamp on one side but a a spring locking wire on the other. What this does is enables the flex pipe to rotate and move in out on the hard pipe creating leaks. At 28K miles I ditched the twin intercooler for a single front mount and found two leaks. Now it is possible that Fiat did some upgrades from the Abarth but I am glad the V6 is in the Trailhawk. I just wish you could get a manual.

There is no v6 in the Renegade...the 2.4 is v4.

I also have the 1.4 in my Dodge Dart and love the engine.

It's a small displacement turbo four. It's going to be peaky. Variable valve timing will help, but even if they added gdi, I don't think it would eliminate it.

I had a 2.0 turbo four years ago, no variable valve timing, and that sucker was peaky. Hard acceleration with full boost and part throttle would also make it retard timing like there was no tomorrow.

Thanks for the correction on the V6.

Have you done the wastegate mod?

also from what I understand emission standards end up exacerbating their peaky natures as well...

Part of the problem, before late '13, the wastegate wasn't adjusted properly on the 1.4Ts.

They came with 0.00 to .50 mm preload, the later turbos came with 10 to 12mm preload. A lot of the owners of the 1.4Ts, myself included, checked our perload, and upped it to the 5 to 6mm range and noticed it smoothed out the engine. I might go higher if I had a boost gauge but, afraid of the overboost.

No... what does that entail?

 

[Rivmage]

This is based on the Dart but, it has the same 1.4T.

V4 or inline 4?
