Mazda 3.0 to Ford 4.0???

[uscfootball27]

Hi guys I'm here to double check some stuff. I've read and been told about Mazda 3.0 to Ford 4.0 sohc swaps with a 5 speed manual transmission. I currently have the Mazda B3000 5 speed manual. I think that the transmission is an m50d-r1 in both? I've got a few questions.

(1) Can I use the 3.0 manual transmission out of a Mazda, and bolt that up to a 4.0 sohc?

(2) Would the fly wheel to crank shaft bolt pattern be the same?

(3) If we have a 4.0 automatic, and convert it to a manual, is the hole in the crank for the input shaft pilot bearing?

(4) Is the starter the same?

(5) What else would we have to do to convert from a 3.0, to a 4.0 sohc?

(6) Making sure that the transmission in both is an M50D-51?

Thanks a lot guys

the bellhousings are different between a 3.0 and 4.0. You will probably need a different transmission to bolt to the 4.0

First your Mazda 3.0 engine isn't a Mazda engine it's a ford engine
specifically a 3.0 "Vulcan" engine

then again, your Mazda truck really is a "badge engineered" Ranger

the 3.0 engine uses a different EVERYTHING as the engine was originally
designed as a FWD car engine (Ford Taurus).

the 4.0OHV engine is a Ford "Cologne" engine and is actually made
by Ford of Germany in their Cologne engine plant (Spelled "Koln" in germany)
and is a development of the 2.9 V6 engine

The 4.0SOHC is an even later development

The bellhousing, flywheel, Y-pipe, throttle cable are all different.
as is the computer and much of the engine sensor locations.

It's possible to convert, but to the 4.0SOHC? Not nearly practical

And frankly thought he horsepower numbers of the 207HP OHC 4.0 look good
anyone who's driven both offroad would rather have the 4.0OHV (pushrod)
engine simply because it pulls so hard at such a low rpm.

In Fact several SOHC owners right here on TRS have openly
voiced regrets about getting the newer truck with the 4.0SOHC.

why? the 4.0OHV engine is already making 194ft/lb of torque at 1000rpm

I'm one of those people. If I could do it over again with the knowledge I've grown over the last 6 years, I would've bought a 2000(for the OHV).

Yeah, and the SOHC is making what, 190 ft/lb at 1000 rpm? A 5 ft/lb difference, big deal. Anything above ~1700 rpm, the SOHC is making more torque than the OHV. I much, MUCH prefer the SOHC over the OHV. Don't get me wrong, I love the OHV, it's been extremely reliable in my Explorer. But it is no match for my Ranger's SOHC.

I'm not sure I follow this either. The torque curves of both engines have been well documented - there is virtually zero difference at low RPM between them, the curve just extends further up the scale with the SOHC.

Tell me why my friends '98 OHV with 5spd, 3.73's, and 35's is WAYYY more drivable than my '01 SOHC with 5spd, 4.10's, and 35's? Shoot...in a race, after my going to 4.88's and him going to my old 4.10 axles, why is he right there with me? Our trucks are virtually identical in build, save the engine and the gears.

Not to continue to hack the thead, but from what I've experienced, the OHV takes way more kindly to oversize tires than the SOHC.

All I'm doing is stating the facts. The numbers don't lie. Since both trucks are 5 speeds, maybe you're shifting at the wrong time??

LOL. I know how to drive. Thanks.

Perhaps, but you don't seem to understand physics.
