Seems the v6 engines stock dont run anymore than the top end FI cars (about 240 bhp) on here which suggests that stock MX5 gearbox and diff would be up to the job (if the gearbox bolts up). So seems it has advantages. 1) power is more than a k'nacked old Rover V8 but its cheaper than a mahoosive 5.3L V8. 2) could potentially keep diff (and

They've been powering Fords since 2007 and also saw duty in Mazda vehicles. The worst thing about it is the water pump is internal and is turned by the timing chain in front wheel drive vehicles.
The 2.3 is loud and thrashy, while the 2.5 is mellower in noise and vibration. Stepping out of a 2.5 after comparing it to a 2.3, the first thoughts that came to mind is that the 2.3 is a POS compared to the 2.5 and why Ford did not start off with the 2.5 rather then give its buyers an underpowered 2.3.
The base engine was the 160 hp (119 kW) Mazda-designed 2.3 L Duratec 23 I4, paired with either a 5-speed manual or 5-speed automatic transmission, both also designed by Mazda. SE and SEL models were also available with a 221 hp (165 kW) 3.0 L Duratec 30 V6 and a 6-speed automatic, made by Aisin Japan. [9]

The 3.5 seems to be the engine of choice for all the expeditors that I've heard from. I'm around 140,000 with no problems. The other expeditors have similar mileages (+/- 10,000 miles) and experiences. The jury is definitely out on today's diesel being economical to maintain long term.

Ford's Lima (Ohio) Engine Plant is producing 325,000 of the 3.5-liter 265 horsepower engines that are being introduced in the Ford Edge, Lincoln MKX and MKZ, Ford Five Hundred and the Mazda CX-9 If you have a high mileage engine there isn't going to be any real harm in adding a seal softening agent to the engine's oil. After years of heat cycling and age those seals have a tendency to harden. On the Duratec, this means the shaft type seals and the pre-shaped O-ring type seals such as used on the timing covers and valve covers.
Duratec Vs. Vulcan (Ford V6s) General Discussion. RedLines June 3, 2013, 6:48am 1. Which do you think is better and why? asemaster June 3, 2013, 7:10am 2. The 3.0 Vulcan is, in my opinion, the most reliable, durable, bulletproof, indestructable V6 engine ever seen on the American road. They never break, save for instances of severe neglect or
ricksgardening said: I called the Ford parts dept today & found out that the oil pan is the same part number for 2022 to 2023 3.5 liter Duratec V6. The 2022 owner manual calls for 6 quarts while the 2023 indicates 12 quarts. Explain that! Still waiting on FoMoCo's reply.
The engine uses an internal combustion engine with a turbocharged Four-stroke type. T. he engine is also equipped with a Power of 280-350 hp (209-261 kW) / 5,500-5,600 with Torque of 305-350 lb-ft (414-475 Nm) / 2,750-3,200. Shoot command using the 1-3-4-2 system. The engine oil weight is SAE 5W-30 with an engine oil capacity of 5.4 l (5.7 qt).
The 2.5L is a good engine although its getting long in tooth, but a work horse for sure. Its also port injected (wet intake valve) not direct injected (dry intake valve) like the ecoboost engines so the carbon build-up one the back of the intake valve won't be an issue as the fuel injected in the intake port tends to keep the backside of intake valve cleaned off.
Feb 15, 2020. #2. The 3.5 EcoBoost is a Duratec engine, just a GDI version of the 3.5 Duratec, so they. should use the same heads. Inside the head may be different, the DOHC cam setup for. the Mustang The 3.7 Duratec (code name Cyclone) is the N/A motor for heavy or premium vehicles. The stroke is the same as the DT 3.5, with a bigger bore.
Further, the 3.5 Duratec engine is smaller than the conventional V6 engines as it can fit in smaller engine bays. The official power output of the Ford 3.5 Duratec engine is 265 HP and 250 lb-ft of torque on 87 octane gas. This power production is higher than the Duratec 30 and floored other V6 engines when it was released.
