3L Duratec

A stock 3L motor requires extensive modification to bolt into a Contour or Cougar engine bay. Our 3L engine blocks are modified and bolt directly into the Contour/Cougar engine bays like a stock 2.5L. The heads are machined to allow for the 2.5L intake manifolds (upper and lower) to bolt on directly without any modifications. The block modifications allow for all the 2.5L accessories and sensors to bolt directly up to our 3L like it would on any stock 2.5L. When the 3L is installed the engine will appear identical to a stock 2.5L. Installation will be done exactly as any 2.5L install.

**2.5L Core Parts***

3L builds require the following parts from a 2.5L engine:

timing cover and mounting bolts ($75)
valve covers and mounting bolts ($75)
engine mount and mounting bolts ($50)

Normally we will have a stock of some parts on hand to complete engine builds in a timely fashion. Customers will have pay the core charge up front unless they send us the core parts listed above. If the core charge is paid up front the customer has 30 days to send back the 2.5L parts along with the install bolts. Once the parts have been returned and are in good condition the core charge will be refunded. The engine mount does require you to pull a cylinder head for removal which is normally easier to do when the engine is out of the car.

Tuning Information

We recommended the use of 19lb injectors with our 3L swaps. Contour SVT's all come with 19lb injectors so no action is needed if you have an SVT other than swapping over your old injectors into the new engine. If you have a 2.5L Cougar or Non-SVT Contour 2.5L then you will have 17lb injectors. You can still use the 17lb injectors but keep in mind you
will be close to maxing them out. A dyno tune would be recommended to verify they are supplying enough fuel in the case you stick with your stock 17's or even if you switch to 19's so you can tune for the larger injectors.

It is recommended that you have a skilled mechanic install these engines. It is also recommended that you acquire a tune for your vehicle after install (contact us directly for more information and recommendations). All engines come with a basic 30 day warranty.
