2.5 V6 147

I found an advert on E-Bay claiming to offer a recon 2.5 V6 engine suitable for "alfa 156,147,166,gtv,spider". Is this a misprint or can that engine actually be fitted to a standard 147? Maybe just GTA???

I guess if you can get the GTA engine in there then it must be possible. The V6 is a very tight fit in the 156 and although the 147 looks smaller I assume the engine bay must be practically the same size - would make for an interesting project as the V6 is such a fantastic engine

Thanks, my thoughts exactly.

I would really like more power (V6 especially) but can't afford a GTA, don't really want to trade up to a 2.0 (I don't think there is enough performance difference) and bascially I like the car I've got. On paper at least, the 2.5 V6 looks like an affordable way of getting a V6 into my 147 and some decent improvements in bhp and noise!.

If it's possible, has anyone had a go at this and was it worth it?

On one Czech Alfa Romeo forum http://www.alfa156.cz/ I remember to read posts from a guy who fitted 3.0 V6 from 164 to Alfa 156 2.0 TS and refitted Q4 crosswagon rear axle, diff and driveshaft and now drives 156, 3,0 V6 Q4. He made this even road legal as "car rebuild from original homologized parts" :-) I might try to find his email if you like, he has some experience: D

that would be great, any info would be useful.

realistically you may as well go for the 3.0 over the 2.5 as its no harder to fit and no more expensive to buy really

That sounds really interesting, if you have alink of some kind please share, as I don't understand one word in Czech.

The 2.5 is a really weak motor (under powered). Go test drive a 2.5 first, they are a bit lazy. You would be happier with a 3.0.

I can’t find the post anymore; I made a thread on the Czech forum that I am looking for this guy and more info about the re-built. If he contacts me I will post more info or if the guy speaks English, I will invite him to come here and post.

Thanks for all the advice.

The 3.0 V6 looks like the better option to investigate. I've seen a few 3.0 V6 GTVs in breakers and have been quoted £800 for a engine with 50K miles on it. Need to start looking at the big picture now and try to get an understanding of what is going to be involved here, gearbox, aircon, steering??

Sounds like a bit of a nightmare, but if it can be done for less than £3000 it may be worth having a go at it.

if you can do all the work yourself then below £3000 should be a fairly easy proposition.wouldnt think you would need to change the steering rack but not sure about the track difference.pretty sure your 147 will run different gearbox and shafts so will need box,shafts and the hubs off the 3.0 car so maybe some front suspension too and also the discs and calipers.probably best to find a damaged repairable/salvage car and remove what you need off it and sell the rest.if your planning on paying someone to do the conversion for you,forget it £3k wont be enough imo

I think 3000 is about right, even if he pays somebody to do it, but it's very close to the limit Just need to find the parts cheap, and there are plenty of guys on this forum who can help with advice.

As for the Q4 transplant, that is what I am very very interested in.

would imagine some structural reworking would have to be done to fit the 4wd system,especially the propshaft and your gonna have to rehouse the fuel tank and change ALL the rear suspension

I do not think the fuel tank is a problem, but I'll have to wait and see, must see what the guy that already did this says.

You would just use the bits from a 156 Q4 or 156 Crosswagon.

But yes if you were going to do it, fit a 3.0, don't bother with the 2.5


Edit: forgot we were talking about 147, so some of the 156 Q4/Crosswagon bits may not fit at all.

Heck, I was talking about the 156 as well. 156 GTA to be precise.

Q4 would suit the GTA as long as it didn't waste too much engine power in the transmisson.

But that could be remedied with a supercharger

maybe I'll not bother after all, just seen this on autotrader.....(I'm guessing this is not as it seems).

GOOD NEWS, I am in contact with the guy who did the transplantation. I already have some info (amazing stuff) but I asked him for more and pictures. If he replies I will post here, if not than today evening I will translate all info I have so far and post here.

One interesting thing, he had the Q4 diff modified to swap front/rear axle torque distribution, so that it distributes more torque to the rear. He even says he had seen a 147 Q4, but only once and doesn’t have contact on the owner.

More info to come today later in the evening :-)

would be suspicious of that price with only 24.5k on clock

I've emailed the seller but no reply as yet.

I'm talking from experience here:

It'll work out cheaper to buy a GTA.

Click on the in my sig and consider that I started with a 2.5, so I had the wiring loom, ECU, subframe, steering rack, GEARBOX, engine mounts, drive shafts, ancilleries etc etc befor I started....

Its not worth it.

It will fit, though. Best way of doing it would be to fin a crashed 156 v6 minus engine, buy a 3.0 v6 and combine all 3.

id be very suspicious of that year GTA with that mileage at that price.
