Twinny to v6

How easy complicated is it to put 2.5 v 6 in a 147 2.0 anyone know if its possibility .
Is there a suitable ecu and do you need to change the front suspension etc..

It has been done, but it is a lot of work.

Anything is possible if you throw enough time & money at it.

Think you will also need the car loom which then causes the big issue .. the 147 and 156 are different so unless you get the V6 from a 147 GTA it ain't going to work. 147 is the Canbus system, 156 isn't so all electrics are different and not interchangeable.

Ok thanks guys just after having a twinny with bottom end failure and then changing the engine and having that throw a rod 70miles latter and what seems to be a very hit and miss thing with twinny engines I can honestly say I dont want to try another one.
Had a busso for 10 years and its never missed a beat .
Have to say this experience has totally put me off the twinny.
Drove boxers for years and apart from some tunninig setup issues with the twin carbs never had a problem with those either.
Think the 147 is off to the scrappy.
Nice to look at but this alfa experience has seriously tainted my view.

The vast majority of Twinspark owners never have an issue either, but I can understand why 2 failures has tainted your view.

Yes I did new everything ran fine for 2 weeks so what did I miss.
It started first time ran smooth . No warning lights no faults ha the help of a mechanic so what did I do wrong then.
Why would it run fine for 2 weeks with no problem then let go.
I'm curious to know .
It had new belts both timing and balance belts tensioners w/pump oil and filter.
Set up a per all instructions using cam locks and TDC gauge.
It was wound round several times by hand to check and recheck the belts and tensioners.
You don't think it maybe a bad engine.
Didn't have this problem with my 3.0 24v after I had done the belt on that still fine after 4 years
Nor have I had a problem in the last 30 years doing similar engine belt changes with any of the Alfa suds or 33's I've worked on.
So yes I fitted myself.

I'm not questioning your ability to do it yourself, I'm actually impressed . I thought that if you had a garage do it you would have some come back.

My TS threw a rod but only because the previous owner constantly ran it with no oil. It even went for a year afterwards (5k miles) before a rod punched through the block.

Did it start tapping then knocking 5 miles before?

sorry missunderstood .
yes it felt like I had lost a coil pack just didnt want to accelerate normally would have stopped but was a couple of miles from home just before the off turn on the dual carridge way so let it roll then tried to get it somewhere I could pullover and about 500 meters further on it just blew
big time.
I do appologise if I miss understood just a bit self aware and still trying to think what happened
still a bit odd.
The best bit was the low oil light came on just after followed by the engine management light and I thought that was good then .

Sounds awful luck. I prefer the Busso every time over the TS.
Mind you, my 2.0TS has 130,000 miles on it and uses a litre of oil about every 5000 miles, so they do vary a lot.
Not that that's any consolation to the OP.

In aqll honesty I think I was just unlucky its just one of those things where did it all got the mot about 70 including a couple of minor bits then got the tax 154 + 62 up front on the insurance and then that
Wouldnt have minded if it had gone after fitting it just had to wait till I'd spent every last penny
Now got a car with 11mts MOT 5 mts tax and no money to fix it
