Parts list for engine swap

[mj_2284]

I recently bought a 3.0 duratec motor for my 99 mercury cougar which currently has the 2.5 in it. I also bought the SVT 2.5 contour, heads, intake upper/lower. And I need to know all the stuff I need to change can anyone help me out?

search first, ask questions later?

um, did you notice this thread? it's near the top of this forum. you might want to look through some of the others, too.

first u need to see if you are doing a hybrid or a portmatched 3L

[mj_2284]

well we were going to do a 2.5 svt heads with cams and upper and lower svt with tb onto a 3.0l out of a 2001 taurus

[fordrule]

port match the upper and lower svt to the 3L heads and use the svt cams.
remember to use the SVT TIMING equiptment from the 2.5

its called a port match

why do you recomend doing it that way?

Additional oil flow of the 3.0 heads.


There are three ways to do a 3.0 swap:

1. Hybrid - This means using a 3.0 block with 2.5 SVT or non-SVT heads and upper and lower intake manifolds.

Pros - easy, cheap, high compression for good power

Cons - high compression means forgetting about forced induction, still have the poor oil flow of the 2.5 heads. Lots of hybrids have spun bearings.



2. Straight 3.0 swap - Installing the engine with the 3 liter heads and intakes intact.

Pros - No head swaps/work required, good power and torque.

Cons - Risking up a fuel rail leak by having to fab up the fuel rail, also the EGR tube. Not easy to do.



3. Split port matched - 3 Liter engines have oval port heads. 2.5 engines have split port heads. "Port Matching" means you are porting out and converting the 3.0 oval ported heads to match up to the 2.5 split port intake manifold. Read the thread by Aircougar1 about port matching.

Pros - Looks and seems like a stock engine to anyone working on the car (local garage, etc). Does not require custom fabbed parts like fuel rails or EGR tubes.

Cons - Porting out the heads is a bit of work. Also, the straight 3.0 swap fanbois will threaten to eat your children.

thanks i am going to go with the port match idea cuz i have done alot of porting cast heads ford small block fords so it doesn't seem like alot of work to me thanks for the good info!!!!!

Don't forget a loss in performance, especially when used with a 2.5L UIM.

Also, SVT camshafts can be used in an oval port for best max performance.

The "poor oil flow of the 2.5 heads" only applies to 2.5s from 2000 or PRIOR. From 2001 up, Ford added the "missing" oil drain back in the heads that the 3.0 has. FYI.

Are they the same Mark? So if building a 3.0 hybrid with late model 2.5 heads, you wouldn't have to plug those oil ports in the 3.0 block? I've never heard a definite answer to that...

Unfortunately, that I do not know for sure. I would assume that it's in the same spot, but you know what happens when you assume. :shrug:

I've got a set of SVT heads in the basement, but I've never seen the late model 2.5 heads or the 3.0 heads. Maybe someone could find a pic in this forum? Not many late model 2.5 owners have done a swap, AFAIK.

oh hush up henry its a ****ing joke.


No matter what you do 3l is a good investment in these cars if done right.
