Been thinking about this for a while now , seeing as the 2.2 3.2 and the 2.4 Jtd all have issues that we all know about , and the subject been done to death ! If you had a choice what would be the perfect engine to make it go as good as it looks ???

The Fiat 2.0 20v turbo was abysmal for mpg, but it was very quick.
The 2.2's so-so for mpg, and not very quick.
The 1.75 turbo they did eventually stick in seems a fair enough compromise.

No oilburners on the list yet.....?

Ive thought about this, and i think a v8 is wrong for the car, I think they should have twin turbod the V6 they put in it, taken it up to about 350 bhp, if the 400 bhp figure above is correct it would have been bad to monopolise the chassis with power.

The more I think about it the more I think you are right. The Nissan VR38DETT would be a perfect option giving 3.8-4.0 N/A and the option for single or twin blowers giving you 350-1250 WHP possibilities :thumbs:
(its what powers the Nissan GTR if your wondering)
For cost, I would still do a short block 2JZ. Similar power available through forced induction and its a short / thin engine (inline 6) so would be much easier to transplant into the engine bay in a longitudinal position

I believe that the latest Brera (with it's small weight reduction) and the 1.75 turbocharged engine, still is the best overall choice. Also, one can go for a 1st stage engine upgrade to achieve bigger torque numbers that this beauty needs so much.
But, if I could fit any engine, that would be a 4.2 405PS F136 U Ferrari/ Maserati that is powering the GranTurismo.

I agree and think that both the Brera and 159 Q4 would certainly do justice to the Supercharged V6 engine (AJ126) found in the F-Type Jaguar, in either 340 or 380 PS guise.

The 2.5 24v V6 is not a great engine.
Terrible torque curve, it would have been a nightmare in a car as heavy as the 159/Brera.

I didn't think the Fiat 20vt was bad. And old colleague of mine used to get mid 30s commuting on the M1 and with a bit of stop start traffic. That's with a 90s ECU & injection technology. A new cylinder head with direct injection, a more optimised intake & exhaust setup and a more modern turbocharger should have given good figures, more so in the real world than on the testing rig. Look at what BMW achieve with the 335i, and thats a 3 litre engine in a car thats just as heavy as a Brera. The 20v petrol block is part of the same engine family as the diesels, there are a lot of similarities. I can't think that it wouldn't have been cost effective, as it all could have been installed with the same mounting points as the 2.4 JTDM and using the same gearbox albeit with more suitable ratios.
I like the 2.2 JTS, its just not enough engine for the Brera & 159. It would have been great as an update of the 2.0 JTS in the GT.

I never understood why Alfa did not develop that 5cylinder 20v Fiat Engine.
I had one in my HGT and it was a good powerplant with a distinctive sound.
Cambelt changes were a bit of a nightmare but that was because it was shoehorned into the hatchback engine bay.

Think it's because they didn't have another decent Fiat to put a more developed unit in. And by adding a bigger turbo means more turbo lag or they could of melted the the cylinder head. So IMO money wasted on R&D, with a car that will never sell in huge numbers. The number of Italian cars built, will always be up & down in numbers each year. By that time it becomes old tech, as the motoring world moves on.
They still look good though, those Fiat Coup'es :thumbs:
:thumbs: Agreed.
So many great details like the body-coloured dash with the 'Pininfarina' script, the lights, the petrol filler cap...
It was Alfa GTV v Fiat Coupe for me back in the day. Alfa won that one, but the Fiat was a very close second

Ditto, discussed this with Jano about 2 years ago and he felt it could be made to fit as long as it stayed n/a no room for turbo or SC but all that would have been needed was:
New loom
New engine mounts
New custom made propshaft
Remove awd for R&D
Reshape the tunnel
Blister/bulge in bonnet
Widening of the bay by cutting away some internal steel around the bay
New exhaust
I think our quick sums came to about 10k plus donor engine = I'd still do it if my numbers came up:thumbs:

not sure about that engine, Jaguar basically didn't want to spend development money on it, so they just used the V8 block and the first two cylinders are empty!
So you end up with the weight of a V8, the engine weight not as far back as it should be and an unusual 90 degree V6
