I'm driving a 83-modell Ford using the 2,8-litre Ford Cologne V6-engine, and I'm thinking about changing the engine into a 2,9 or 4,0-litre Cologne.
Are the 2,9 are 4,0-litre engines the same or similar in size? (outer measurements)
Can I use the engine mounts from the 2,8 for the 2,9 or 4,0-litre?
Will the inlet manifold from a 2,8 fit the 2,9 or 4,0? Will an inlet manifold from the 2,9 fit the 4,0?

I have a 2.9 that I need to get rid of because I recently cooked it. I want to do a motor swap, and I was just gonna replace it with another 2.9, but I was told a 4.0 would fit just the same as a 2.9, same motor mounts and everything, but would require the computer from the car that had the 4.0. As for the 2.8, I'm not sure. I figure that from the .1L increase between the '85 and '86 Bronco II's that the motor mounts and such wouldn't have to change, so I figure either motor would fit, and if so, then the 4.0 should fit. Personally, though, I would talk to someone else who knows more about this....

 

Dinosaur that I am, if it ever comes down to replacing the 2.8 in my Bronco II, I'll probably go with a 289 V-8 and keep the go fast parts to a minimum on that.

I don't believe the intakes will swap out between the various Cologne V-6 engines. If I was going to go to a different V-6, I'd get the 4.0 along with it's transmission from a newer Ranger/Exploder.

Oh, I also just thought of this...

would swapping a 4.0 in my BII affect exhaust emissions using the current exhaust, or would I have to buy a new exhaust to match the 4.0?

 

Are you in Europe?? The Euro 2.8 Cologne heads are different
than the Federal (US spec) Heads, no, the intake from the 2.8
won't fit the 2.9 without some serious machine work, as the
ports/bolt holes are in different locations, as for the 4.0, thats
right out, as it's got a taller deck than the 2.6/2.8/2.9...as for
engine mounts, don't know for sure...

 

What about putting Federal heads on a Euro 2,8 Cologne? Is that possible? Will my old intake still fit?

I'm not sure, as I've never held a Euro head in my
hands, the real trouble may be the thermostat, on the
Euro-spec engine, Isn't it down low on the front cover??

I may be able to tell you in a couple of weeks, I've got
a 2.6L Cologne I'm getting ready to pull from my MG-B-GT
for a rebuild, I can scrounge up a couple of US-spec heads
from a "scrappie" in the area...

 

Yeah, the thermostat on the Euro-spec engine is down low on the front cover, below the left cylinder bank.
Where is the thermostat on the US-spec engine? And if it's possible to change to US-spec heads, would this affect the flow of the coolant? Will a intake from a US-spec engine fit a Euro-spec engine and vice versa?

 

On the "US spec" engines, the 'stat is also down low (at least for 83 and 84.) "US spec" is actually a misnomer. In this thread it means an 80's Ranger engine. The 2.8 also came in some cars in the US in the '70's.

If you want to do some serious mods to this engine, get the book "How to Build and Modify Ford 60 degree V-6 Engines" by Sven Pruett. Then you too can drool over pictures of a DOHC 4 valve/cyl Cosworth head for the 2.9.

 

...DOHC 4 valve/cyl Cosworth head for the 2.9.

Profanity Removed? Tight!

 

The 2,9i 24v Cosworth-engine is quite easy to get your hands on here in Europe, because it was used in the Ford Scorpio 2,9i 24v Cosworth. Was this engine never delivered in the US?

 

On my late '85 2.8 the thermostat is up high in front of the intake.

Unfortunately, No. The powers that be in Dearborn don't
like to sell cars that will outperform the Mustang. This was
really evident in the late 70's, as the last Euro Capris we saw
could, and did. As you guys got the Capris through the mid
'80's, we got stuck with the Fox bodied Capris, which weighed
in at about 3400lbs, which would be about 600lbs more than
yours...

 

While this is true, the Euro spec engine has only 2 exhaust ports,
where the US spec engine has 3, also the 2.9L has a timing chain,
where the 2.8L has timing gears...

 

The mounts are different between the 2.8 and 2.9 in rangers/bronco 2's. I believe the 4.0 is also different. When swapping in a 4.0 into an earlier ranger/B2, the wire harness, computer, and tranny is usually swapped with it, as the tranny's used behind the 2.8's and 2.9's would grenade behind them, let alone a 4.0.

My late 85 B2 (manufactured 7/85) also had the t-stat in the upper water neck.

If going from 2.8 to 4.0, you'll also need to add the fuel injection pumps/lines/tank in the case of a ranger/B2 swap.
