What is the 3.0L Vulcan? What are it's specs?
The 3.0L Vulcan V6 is an overhead-valve six-cylinder engine that has been used in a variety of Ford vehicles for many years, from the Ford Taurus and Mercury Sable to the Ford Ranger and Aerostar. From 1992 to 1994, it was available as an option on all Tempos and Topazes, and standard equipment on all 1992 sport models. The specifications are available here. Among Tempo/Topaz enthusiasts, a V6 model is the most sought-after for its combination of power, smooth operation, and good fuel economy.
Horsepower and torque figures, as well as more detailed specifications for the 3.0L Vulcan V6 can be found in the Tech Center.

Is the V6 a direct swap into the Tempo/Topaz?
For all 1992-1994 vehicles, the answer is yes! The Vulcan will bolt right in with absolutely no alterations to the frame or chassis. The engine itself does not have to come from a V6 Tempo/Topaz, as one of our members has a 1994 Topaz with a Vulcan V6 out of a Taurus. You are advised to buy a V6 Tempo/Topaz parts car if you are going to attempt this swap, however, so that you will have all the parts at your disposal.
Since the engine compartment was virtually unchanged from 1984-1994, one can assume that a V6 swap into a 1984-1991 Tempo/Topaz could work with minor alterations, but no member of the TTCCNA has tried it (yet). You will need to swap over the wiring harness from the V6 donor car, as well as the EEC-IV computer, because of the different fuel injection system.

How reliable is the Vulcan V6? Is it suitable for supercharging?
The Vulcan V6 has proven to be an extremely reliable engine over time and is known to be capable of 200,000 miles or more if well cared for.
Supercharger kits are available for the Vulcan, but no one has supercharged a V6 T/T yet to our knowledge. As with turbocharging, supercharging requires high-performance engine components and a very well maintained engine. Regardless of the forced induction system you want to apply, if your engine has high mileage, you should seriously consider rebuilding it.
