What kind of engines can be swapped into a GTV6 2.5?
Sorry if this has been asked before..couldnt find it...and other than finding a 3.0L , what engines? I'm talking about the 81-86 GTV6 of course...can any models from the 90s be fitted in? Where would one go about finding possible engines...I found a bunch in ebay but from the UK (makes sense), im from california

Also any of the 4 cyl Nord motors. A turbocharged TS would be great.

Not with no issues, there are some changes from a fwd V6 to get it to fit in a GTV6, check out the thread in the Milano section for Roxanne. Jes does a really good job going into the detail of what it takes to get a 12v 3.0 V6 into a rwd chasis. I think there maybe a few additional issues with the 24v motor, but it will at least give you a good idea about what it takes.

The simplest engine is the 3.0 from the Verde, it's pretty much a bolt in.
Any of the 2.0 variants will fit, that motor came in the Alfetta. But now you're looking at parts - headers, fuel system, ECU, etc.
The 2.0 TS from the later cars would be a nice swap, imo, you're still looking at parts, but that motor came in the Milano (75) in Europe, so it should be readily available. Depending on what you do, you'll end up with similar HP to your 2.5, with around 100 fewer lbs over the front wheels. If you've ever driven an Alfetta, there's an appreciable difference.
Any of the 3.0 variants from the 164 can be made to fit, but there are issues there as well, sump, intake, etc etc. If you opt for the 24v, you need to fabricate headers as well.
Personally, I think the 3.0 from the Verde is a great update to a GTV6, if you're looking for more than that, it's going to start costing you $$$. For any 163 3.0 variant (with the exception of the 24v), I'd think it would be just as easy to build a Verde motor to 164 specs, as opposed to making the 164 motor fit. A lot of the effort in making the 164 motor fit involves finding Verde parts anyhow..

Agreed bshorey.
I have just completed putting in a 3 litre from an Alfa 75(Milano), into my Racing GTV6.
As you would already know the engine was a 90 Degree engine and there for was very straight forward beside a few small things.
Because the Alfa 164 onwards are 60 Degrees and front wheel drive, there are too many mods to be a straight swap. You need to spend big $$$.
The engine from a 75(Milano) would be your best bet.

Wot? the alfa v6's are 60 degree not 90!. and you dont need to spend big bucks on the 164 conversion at all. there are just more issues with flywheel spacing, front pulleys, intake set up and Motronic set up. All of which can be done on a budget. Infact you will get a 164 v6 much cheaper than a 75 v6 in europe.

Depending on where in the world you are, you may be lucky to find a donor 75 3.0 Motronic. I believe these were the last model years of the 75 3.0 V6 QV (1991-1992). In Australia I think these go under the name 75 Potenziata. I don't recall if these were basically S-spec engines, but I suspect so, or at least close.

I put a 164S engine into my Milano race car on a budget - Motronic, 164 harness, everything - it runs great. You do not need Verde parts to put a 164 engine into a Milano/GTV6. A (cheap) late-style 2.5 Milano engine will do as donor for parts - plenty of those around. I did not use a single 3.0 part putting the S-engine into my Milano race car (originally this was a 2.5).

No argument wrt which one was better, I was simply trying to point out that the Verde 3.0 is essentially a bolt in, and that you need to add $$$ and time for other (better) alternatives.
You're also right about using 2.5 parts as opposed to 3.0 parts to make the 164 motor fit. Good point.

It depends on where in the world you are, but 164 3.0 in North America:
164B, L: 12 valve, about 182 HP
164S: 12 valve, about 200 HP
164LS: 24 valve, about 210 HP
164Q: 24 valve, about 236 HP
All approximate off the top of my head. Verde 3.0 is 182.
