Duratec bellhousing?

[shooff82]

I've read that the 3.4 shares the same bellhousing as the duratec motors. They put duratec 3.0s in rangers didn't they? I've also read that the lincoln ls(not the ls mkVIII or LSC) also shares this bellhousing pattern. I have a '97 parts car with a bad headgasket and I have an idea.... An involved idea, but it would be badass if I can pull it off!

Yes, they put Duratec 3.0s in Rangers, but only in recent model years. The Lincoln is a fit as well, but auto only?

rangers have never seen duratecs. and you can get a 3.0 LS in a stick. they're rare, but they're out there.

mazda6's have a duratec 3.0 engine aswell, unless your looking for a rwd tranny. in which case the lincoln ls 3L came in a stick, not the strongest from what i've read.

 

[SuperHO]

i'm pretty sure the lincoln LS was the only RWD trans ever bolted to the duratec. you can check into new mustang trans's, but i'm not sure if the 3.7 has the same bellhousing or not.

 

[warmonger]

the new "duratecs" arent the same as the original duratec 2.5/3.0's...name only

This will tell you what cars the Duratec engine(s) have been in:

And this will tell you about the bellhousing bolt patterns:

2011 Mustang has the Duratec37 in it. Just sayin'

 

[warmonger]

like i said...the duratec 2.5 and 3.0 are the only ones with the same patern as the 3.4 v8

 

[jonheese]

The Wikipedia article I linked above says that a single common bellhousing bolt pattern is shared by the 3.4L V8, and the 2.5/3.0/3.5L Duratec. It doesn't mention the (new) 3.7L though.

YMMV, it is Wikipedia, after all.

 

[SuperHO]

And as far as I can tell, the only RWD trans that ANY of those engines was bolted to was the Lincoln LS trans.

 

[jonheese]

The only wildcard is the Mustang. The Duratec article specifically says:

A few days before the 2009 Los Angeles International Auto Show, Ford unveiled a new version of the Duratec 37 for the 2011 Mustang, making it the first Duratec-badged V6 since the Lincoln LS to be used in a production rear-wheel drive car.

So the $64,000 question is whether or not the 3.7L Duratec has the same bellhousing bolt pattern as the smaller Duratecs. One would assume, since it's just a 3mm overbore, that it would, but stranger things have happened...

Wrong, but so was I. Rangers have the 2.3 Duratec, which does not share the bellhousing of the larger Duratecs.

 

[SuperHO]

well i'll be...and here i thought the only DOHC rangers out there were 4.6 cobra swaps. to the OP, it wouldn't be difficult to have a custom bell housing built that'd bolt up to a much stronger trans than what's offered.

the 3.4 is not 100% common to the 2.5 / 3.0 but it is quite compatible. Biggest issue I found from the Ford 2.5 (Contour SVT with the MTX-75) was the one block to tranny dowel on the 3.4 was entirely outside of the bellhousing on the MTX-75 so getitng the tranny aligned right on centerline was looking like a real challenge. I have described this several times, but I just hacked up a quick pic on my server of what exactly I mean here.

Now on the Mazda 3.0 from the Mazda 6 (2004, 5, or 6 I believe) which is the tranny I actually ended up using; the dowel location is also different for the left bank, but where the V8's dowel is aligns spot on with a machined bolt hole in the tranny, but that hole is about .150" to small in bore. I simply reamed about .020" per pass until that hole was the correct size since it was a machine hole, and not just a casting hole.

How close the Mazda 3.0 aligns with the late nineties Duratec30 I can't personally speak for. But the family heritage is fairly evident I believe.

I still majorly owe the community a write-up on the MTX install process, I guess this piecemeal approach on the forum is the best I can do for now. Maybe I'll bring the laptop to the convention and pound out about 30 minutes of typing a night. But if I do it at night after the parking lot there will be an awful lot of proofreading to do I suspect when I awake in the mornings....

 

[jonheese]

Yeah, that's right, I remember the pics you posted on the V8 list of the different dowel locations... But it's pretty darn close-- a lot closer than any other randomly-chosen Ford transmission would be.

I vote for un-proofread post-parking lot write-up. More entertaining.

My typing is bad enough without partying first. I think the entire document would be a waste of bandwidth for anyone to download at that point.

I was just kidding.
