There were 2 Duratec 25's and I'm thinking that the Duratec 30 is more like the later (AJ) version found in the MPV.
Or are the Jag and SVT engines similar? If so, what's different about the MPV engine?

Duratec 25
The Duratec 25 is a 2.5 L (2544 cc) 60° V6 and was introduced in 1994. It was developed for the Ford Mondeo and used in the Ford Contour, Ford Cougar, Jaguar X-Type, and others. The Duratec 25 was on the Ward's 10 Best Engines list for 1995 and 1996, and the SVT version made the list for 1998 and 1999.
An SVT version produced 195 hp (145 kW) and 165 ft·lbf (224 N·m) in 1998. Further improvements were made in 1999 that raised power output to 200 hp (149 kW) and 169 ft·lbf (229 N·m) and were carried over in the 2000 model. The SVT engine was used in the 1998-2000 Ford Contour SVT.
Bore is 82.4 mm and stroke is 79.5 mm on most 2.5 L Mondeo-derived engines for a total of 2544 cc.
Mazda used the same block and camshaft in their 2000 MPV. However, they reduced the size to 2.49 L to keep under a 2.5 L tax cap in Japan. It was replaced in 2002 with the larger 3.0 L Duratec 30-based Mazda AJ.
Duratec 30
The Ford Duratec 30 Engine in a Mercury Sable.The 3.0 L Duratec 30 or Mazda AJ was introduced in 1996 as a replacement for the 232 in³ (3.8 L) Essex V6 in the Taurus/Sable. It has 2967 cc of displacement and produces between 200 and 240 hp (150 and 180 kW). The same basic engine is used in the Jaguar S-Type, Lincoln LS, Mazda MPV, Mazda6, Mondeo ST220 and many other Ford vehicles. It is essentially a bored-out (to 89 mm) Duratec 25 and is built in Ford Motor Company's Cleveland, OH #2 plant. A slightly modified version for the Ford Five Hundred entered production at the Cleveland, OH #1 plant in 2004.
There are two key versions of the Duratec 30:
DAMB - The Lincoln LS and Jaguar AJ30 versions have direct-acting mechanical bucket (DAMB) tappets. Output is 232 hp (173 kW) at 6750 RPM with 220 ft·lbf (298 N·m) of torque at 4500 rpm.
RFF - The Taurus/Sable/Escape version uses roller finger followers (RFF) instead and produces 201 hp (150 kW) at 5900 RPM with 207 ft·lbf (281 N·m) of torque at 4400 rpm.
The 2006 Ford Fusion, Mercury Milan, and Lincoln Zephyr feature a version of the Duratec 30 utilizing variable valve timing. The engine has an output of 221 hp (165 kW) at 6250 rpm, and 205 ft·lbf (278 N·m) of torque at 4800 rpm.
A Twin-turbocharged version of this engine is used in the Noble M400, a British supercar. The engine is rebuilt and tuned to a max power of 425 bhp @ 6500 rpm, with a torque figure of 390 ft·lbf @ 5000 rpm. Noble has used forged pistons, an oil cooler, a larger baffled oil sump and extra cooling ducts to maintain its durability.
Mazda's MZI version adds variable valve timing, as does Jaguar's AJ30. Note that the MZI name is also used in Europe on Mazda's version of the Ford Sigma I4. The 3.0 L, 226 hp V6 used in the Mondeo ST220 is called Duratec ST. The 3.0 L, 204 hp V6 in the Mondeo Titanium is called Duratec SE.
