View Full Version : Straight 3.0 swap questions...

Ive been reading up on the swap for a while now, but it wasnt until I started talking to a fellow member(10ktgold) in the process of a swap that I started thinking seriously. The swap that he is doing, and that I am interested in is a full 3.0 swap.
As much as I would love an all-out, balls-to-the-wall hybrid, I dont think it would be smart for my daily driven ATX. I would of course add all my bolt-ons(msds,sho shop ypipe, trubendz duals, CAI, SVT parts), which I think would give me fun, reliable car. Ive got a few questions though that I couldnt really find on doing the full 3.0:

1.) Is the obvious power gains over a straight 3.0 the only reason why almost everyone goes with a hybrid?
2.) I would be going with most likely a 2004 Escape engine. Would this swap would be relatively straightforward, both engines being returnless? Other than the known (block ear grinding for alternator with escape belt, new rad hoses, axle bracket, etc.), what else "major" would need to be done?
3.) I am aware of the hood clearance issues with the escape UIM, so I would be port-matching for my SVT manifolds. Any comments, thoughts, suggestions?
4.) ECU wise, 3.0 ECU and have key reflashed, or stock ECU with an ADC chip?

I would be doing the swap over the winter, so I have plenty of time to pick up parts, knowledge, etc. Please feel free to add or correct any of the above info, especially anyone who's been there. ANY and ALL suggestions and advice will be greatly appreciated. I know I have much to learn before then, but Im hoping you guys can lead me in the right direction. Thanks guys.

Go full 3.0... You won't regret it...

Instead of the escape manifold you need a taurus intake manifold which will fit perfectly... Pretty simple swap since your returnless... In addition to what you listed you gotta mod the throttle body bracket

And don't try to change ECU's escapes ecu's are completely different and pinouts are not the same as contour/cougar ones... Go with ADC

And while your at it swap the bearings with Clevite ones

Most have done the Hybrid as Oval-to-Split port head matching was not offered. Now that it is, the new path has been the Full 3L with head port matching for several reasons. You may want to get your heads port matched (and get them PnP'd at the same time). This way you could still use your SVT intake components that you have.

The trouble you may run into is trying to keep the ATX in one piece under the power of the 3L.

In any case, best of luck to you on your project!

Power is definately noticable going from the stock 2.5L to the 3.0L. I would recommend a full 3L over a hybrid anyway so stick with that route. The best setup would be to port the heads to match the SVT intakes but it isn't necessary. You'll still see nice gains going with the straight 3L. Since your cougar is tuned for 17lb injectors your stuck having to get a chip because you can't use 17lb injectors in that engine without maxing them out. I've had a SVT computer in all the ones I've put together and the cars run perfectly fine without a chip on their stock 19lb injectors. I've had one tuned and it gained only a few hp but the air fuel was right on before the tune so it really didn't even need it. With the stock ECU I'd get a chip from ADC. It won't even be possible to use the 3.0L ECU. Who had hood clearance issues with the 3L UIM? I know if you stick with the 3L IAC it is shorter so it may fit in there. I'm not sure what PuckPuck used on his but I know the stock 2.5L IAC wont' fit without some grinding. They fit perfectly under the Contour hood as long as you use the 3L IAC.

Plastic escape manifolds will not fit, they are much different than taurus manifolds which fit...
With escape manifold the plug wires will not even fit under the manifold as well as the hood won't close firstly because of the iac and secondly the manifold itself

As far as clearances go, do things change if you have the Kaminari hood? I'm replacing my smashed hood with a Kami hood, so I'm curious about what that could change in terms of my planned 3L swap.

So full 3L/ADC/SVT UIM, LIM will fit fine under the hood?

Yes, because a 3L with 2.5L intakes will be the exact same clearance-wise as the 2.5L

Another quick question, if I decide NOT to go with my SVT manifolds and go with the taurus ones as mentioned above, will a chip eliminate the problems caused by not having an IMRC?

Thats pretty interesting because I was thinking about a straight swap...

I would like to go more with 3L Engine/SVT Cams,UIM,LIM,TB 19LBS Injectors SVT ECU and my intake heads of my 2.5 engine.

The things is ...PNP both heads to fit it on the 3.0L Block is really expensive.. Can I do this without port matching ?

Let say this would give me 220hp instead of 240-250 ... thats fine with me ...

Will this work ?

actually best bang for the buck is FULL 3L heads and block. Have the heads split port match to the svt lim and also have the 3L heads PnP. Also the SVT cams, 19# inj WITH a good tune .

The hybrid with the 2.5 heads and 3L block you can go with but you are blocking oil passages in the block and it will be hard to go from 2.5 heads to the 3L heads after its block. correct me if i am wrong 3L gods

Thats great ..Will the 3.0L Intake Manifold fit into the cougar ? I mean what about if I go Full 3.0L engine without the SVT UIM,LIM .... And can I keep the stock injectors from the 3.0L ?? lets say Ill get a ADC Chip... So it would be a straight 3.0L Swap with an ADC Chip .. Is there something I need to add the make the swap a perfect fit ...lets say the engine would be from a Taurus 2001. And where Can I buy some SVT Cams and Injectors ?

u have to custom make a fuel rail if ur car is return system, custom make a egr tubing if using the full 3L uim/lim , YES you need a chip. svt cams you have to search for..i got mine off of ebay

so essientially what would be the best parts to put in a 3L

so essientially what would be the best parts to put in a 3L

If going NA:
-SVT Cams
-SVT upper and lower intake manifolds
-Ported 3L heads
-SVT Throttle body
-Dual Mode Damper crank pully
-GMK Cold Air intake with large K&N Filter
-Headers
-2.5 inch exhaust all the way back
-Tuned SCT Chip from ADC or any reputable shop

That's all I can think of right now....

i used the whole 3.0 from a 04 taurus ,99 intake manifold ,and braized the fuelrail ,gutted cats ,cai ,flowmaster ,and it runs ok with stock computer ,you WILL need to change the metal mounting plate on the escape to the cougar one cause its minus a tranny bolt , but thast it , you have to grind the block and so on ,,plus im running nitrous ,,,,,,,any questions or pics jus pm me , or im i0ktgold

2001/2002 Cougar 2.5L heads do not require blocking oil feeds/galleys on the block, as the 2001/2002 Cougar heads have the same oil feeds/galleys as the 3L. If you do not have the money to spend on porting and polish, then 2.5 SVT/3.0 block hybrid is the way to go, using 01/02 Cougar heads and SVT cams. No oil galleys to fill, the only modifications you need to make are to shave an ear off of the block to fit the alternator, and trim the bushing on the back of the crank to fit the tranny. Everything else will bolt together and fit fine.

With tuning, and thanks to the increased compression ratio from doing the hybrid swap, you will see a very large HP jump (from 170hp stock 2.5 Cougar to approx 220-230 or more), and the torque increase will be phenomenal (from 165tq stock 2.5 Cougar to approx 200+). Tuning will make this all worth it in the end.

Untuned, on the SVT ECU, I saw a hybrid 2.5/3.0 SVT make 190hp/180tq at the wheels. Assuming a very conservative 15% driveline loss, that's about 223hp/211tq.

Which setup would give better gas mileage, Full 3.0L swap tuned or 2.5L/3.0L Hybrid tuned? since the hybrid has a higher compression ratio

Tough to say. The 3L/SVT Hybrid I drove around, untuned, got roughly the same gas mileage as my Cougar, averaging about 25-26mpg with a mix of city and freeway driving.

Blackcoog

I'd say both would get about the same milage. The 3L's no matter what configuration all seem to get normal 2.5L mileage.

if your building a 3L you shouldnt be worried about gas milage because you are gonna be on the throttle so much it wont matter.
