Duratec 35

[Southern_Trendkill]

Has anyone ever tried to put one of these into a ranger?

 

[Wicked_Sludge]

not that ive heard of.

the duratec engine family is supposed to share a common bellhousing bolt pattern. if thats the case, the 3.5 should bolt right to a 2.3 duratec transmission. of coarse this means no 4wd unless you tear the 2.3 trans apart to convert it.

the intake appears to by symmetrical, so it could probably be flipped. coolant lines would have to be rerouted, motor mounts fabbed, wiring harnesses modified, and exhaust work done.

Dont 3.5's have the same bolt pattern as the 3.0 DOHC duratechs, which have the same bolt patterns as the vulcan 3.0 used in rangers that you could get a trans from? Or do I have my bolt patters confused?

 

[rurouni20xx]

3.0 vulcan, 3.0 dohc (taurus sho) and fwd only 3.8s share a bolt pattern, duratec 30 and 35s are the same if im not mistaken, but you cant just bolt it to a vulcan engine or tranny (i wish you could...)

I'm not so sure on the 3.0 Vulcan and 3.0 Mitsubishi motors having the same bolt pattern. It was my understanding that the Vulcan (was also in the non-SHO Taurus cars) is it's own unique pattern. None of the Duratech engines will match a Vulcan pattern for sure.

 

[rurouni20xx]

the taurus sho was a yamaha-ford vulcan project, yamaha made the heads and cam assy that fit on vulcan 3.0 internals. what does mitsu have to do w/ any of this you have piqued my curiosity here. i know they had the tranny line b4 mazda did, thats about all i know.

 

[Roadkill]

Sorry, I knew it was an import company that made the SHO engine. Couldn't quite remember the exact one. I had always heard that the Yamaha SHO engine was it's own beast not similar to any other Ford engine.

If it is indeed a Vulcan block then that makes some swaps much easier. As long as you weld the cams on the SHO engine before the gears spin and blow up things.

hey so does the sho motor share the same internals as the vulvan like the pistons connecting rods and crank?

 

[rurouni20xx]

not sure i would imagine the the pistons are dif tho cuz they have to be milled out for 4 valves instead of just two. the rods etc im unsure about but i would imagine they are similar. the crank will be dif since it has to run the timing system on the heads, and the block will be dif since the cams are in the heads rather than above the crank w/ the usual lifter setup. i know they share a common bolt pattern, i havent seen the engine but i know how dohc 24 valve v6s are setup. when i was considering my options i wouldnt have minded doing a 3.3 stroker sho motor and then boosting it but the crank and internals are dif so i just opted to redo my existing motor. a boosted 3.0 sho swap would b kewl but i already have my motor, and i dont know where a 3.0 sho motor is. easier on me this way than trying to find a motor then working on it. ive looked up the specs but unless i physically tear it down and compare parts i cant tell you if the rods are the same and the block etc. best as i can tell the dohc sho engine is derived from the vulcan ohv engine.

 

[99RangerBoss]

i was thinking if the internals were the same it could be swappable to the ohv block but like you said the valve releifs would screw it up i guess the only way to get a stronger motor would be the morana kit or flatlander racings one

 

[rurouni20xx]

flatlander racing? im going to build a morana 3.3 turbo, ive never heard of flatlander racing.

the taurus sho was a yamaha-ford vulcan project, yamaha made the heads and cam assy that fit on vulcan 3.0 internals.

the 3.0/3.2 SHO used in the '89-94 tauri are all yamaha. ford ORIGINALLY wanted yamaha to use the vulcan block but yamaha took one look at it and said "ya right". so the SHO block is its own unit. the only common thing between the SHO and vulcan is the bellhousing bolt pattern.

SHO internals have been made to fit the vulcan, but it takes excessive machine work on the crank/mains. its anything but bolt-in.

As long as you weld the cams on the SHO engine before the gears spin and blow up things.

thats the v-8 SHO used in the '95 and up taurus'. the 3.0/3.2 SHO does not suffer from this problem (and its non-interference, unlike the v-8). the v-8 IS a ford/yamaha hybrid, using a duratec block with yamaha heads/guts.

the 3.0 vulcan, DOHC 3.0/3.2 SHO, FWD 3.8 block, and 2.3 HSC used in the tempo (NOT related to the 2.3 lima used in rangers/mustangs/t-brids/etc) all share a bellhousing bolt pattern.

the 3.5 duratec, 3.0 duratec, 3.4 SHO, 2.3 duratec...and on down the line.. should all use one bellhousing bolt pattern.

 

[99RangerBoss]

yeah flatlander racing has made custom pistons before for the vulvan and all that shit my buddy was going to sup-up his v-6 tempo at one point and he inquired about it

 

[rurouni20xx]

interesting about the flatlander ill look that up, and your right about the sho engines, i got the v8 and v6 confused. if the sho 3.0 wasnt so much id do the swap, but since i have a 3.0 already im going to build that up instead for less $$$.

I've thought about a 3.0 or 3.2 SHO motor in my 4x4 Bronco II...at first I was put off by the torque peak moving up by 1000RPM, but then I actually saw the tq curve and realized that the SHO motor makes more tq than the 2.9 through the entire rpm range, and the 3.2 isn't far off from the 4.0. Since I've got a shelled trans I'm gonna have to buy one or rebuild anyway, wouldn't be any harder to find another M5OD out of a 3.0 4x4 Ranger instead of a 2.9/4.0 and get a motor to go along.

I kinda fell in love with that engine when I had an SHO and have been wanting to put one in something ever since. I'd love to hear from someone who's done it before, just to know how it drives and whether I'd really want an 8000RPM redline in a 4x4. Then again, the BII doesn't weigh much more than the SHO to start with...
