View Full Version : Yamaha 3.0L SHO V6?

PETC05-12-2006, 01:36 AMIn an MR2?

Anyone ever thought of this?

Just an idea... Raptor13x05-12-2006, 01:43 AMWhy bother? Tons of custom fab work, and there are so many better motors you could put in. If you want a 3L V6, there's Toyota V6's that are cake to install comparatively. canadam05-12-2006, 01:50 AMI've mulled it over many times. Someone has successfully transplanted one in a MKI. I believe there was firewall cutting involved.

Take it from Jim, he's the perfect example of where doing things over your head can take your MR2 :rofl:

As for better, I've never heard anything but praise for the early SHO V6's. Plus, its one of the most gorgeous engines ever produced :) Weasy2k05-12-2006, 07:25 PMtoyota did build that engine Raptor :P Raptor13x05-13-2006, 01:48 AM^ I was under the assumption it was a Ford engine. Weasy2k05-13-2006, 03:09 AMNegative Raptor13x05-13-2006, 05:06 AMSHO as in Taurus.

What other SHO is there? ursoboostd05-13-2006, 08:09 AMWasn't it Toyota/Yamaha that made that engine. -Wade- ALLSHOTUP05-13-2006, 10:41 AMYamah did make that engine and by what I have been told it is extremly relaible. SpeedballTrix05-13-2006, 11:21 AMIt's a Yamaha motor and so is the 3S.
So it's just as kosher in a Toyota as the 3S is, I guess. canadam05-13-2006, 11:43 AMI don't think Toyota had any part in the design of that engine, only Yamaha. It does employ Ford parts. Can anyone confirm otherwise ? docneon05-13-2006, 12:23 PMI was alway under the impression that it was a FORD 3.0 block, the same one used in the regular Taurus and a few other FORDs; however Yamaha did all of the head work including intake and exhaust. As far as it being more reliable, my dad had 210,000 mi. on his 3.0 Aerostar, and I've known quite a few of the SHOs to not reach 100,000 mi.

IMO, I would stick to a Yota v-6 for a transplant. There have been so many done that others can provide tech support. Weasy2k05-13-2006, 12:43 PMthe entire block and head was subcontracted to yamaha, since toyota owns most of yamaha i say toyota, these engines are tough while some had issues in the first years others are rocking boost and 250k miles canadam05-13-2006, 12:56 PMAccording to Wikipedia, Toyota actually only purchased 4% of Yamaha in 2000. In return, Yamaha Corp. and Yamaha Motors each purchased 500,000 shares in Toyota. Weasy2k05-13-2006, 12:58 PMas it stands...toyota owns most of yamaha canadam05-13-2006, 01:15 PMI've always been told that it was 40%, but I can't find any literature stating more than 4%. Weasy2k05-13-2006, 09:23 PMi have read the same number beofre. (40%)
Try looking up the stock news of years ago

should show it in there bucket05-21-2006, 07:53 PMI have thought about this... I have also heard that the block is ford...

I wonder how much the SHO flows compared to a toyota V6? Are we 100% that toyota built the heads for the 1mz and 3mz motors? Or any other motors? If nobody has looked at them side by side it would be willed to find out there the same. I don’t think they are. just thinking out loud.

Chris Weasy2k05-21-2006, 08:10 PMYamaha is one of the top head builders out there i HIGHLY doubt toyota used another company... canadam06-20-2006, 06:28 PMThere's an SHO engine for sale in my area right now for $500. PETC06-20-2006, 06:40 PMDo it. canadam06-20-2006, 07:28 PMThe problem is, the only tranny I know that the SHO engine bolts to is the piece-o-crap Mazda unit as found in the Taurus. Raptor13x06-20-2006, 07:39 PM^ That's what engine adaptors were made for. :D SpeedballTrix06-20-2006, 07:51 PMDO IT ADAM!
Seriously that woudl be awesome jsut to see the potential.
and a complete motor for $500? Sounds like a deal to me. Especially since you can probably talk it down to bucket06-21-2006, 12:56 AMI have a set of 1MZFE heads pulled from a motor. if you dont get it take some pics for me. befor I sell the heads.

chris canadam06-21-2006, 11:50 PMHow would one go about getting something like this custom made?


^ That's what engine adaptors were made for. :D Raptor13x06-21-2006, 11:55 PMI'm sure there's a company out there that either already makes them, or could make them upon request. A decent machine shop could probably help out as well. Here's one company that makes custom engine adaptors, though probably not for that engine: http://www.kennedyeng.com/index.htm 91mr2n70206-28-2006, 03:48 PMI think that while a little crazy, It could work!

Jay Leno has a mid/rear ford festiva with an sho engine. called the shogun does 12s before he hits the 100 shot! diy Plans were available online somewhere.

I had a friend w/a 89 sho 5speed in high school. It ran on many 5.0s. I remember hitting 10,000 rpms. He never had engine problems-he did have to do a tranny.

Motor was a yamaha project 220 horse 3.0 litre most power for displacement in 89.

If you can find a tranny or adapter to oem tranny, could be a sick swap!

If yamaha built the mr2? and yamaha built the sho engine? would they bolt up possibly? canadam06-28-2006, 04:55 PMYamaha only designed the head of the 3SGTE... and unfortunately the SHO engine won't bolt up to a Toyota tranny. Weasy2k06-29-2006, 12:00 AMHow would one go about getting something like this custom made?
Shops out here do it too...expect to pay 1400 for it :) PETC07-02-2006, 08:18 PMStep 1: Do research/design
Step 2: Comondeer an engineering student at a reputable university
Step 3: Cheap CNC work! w00t! jlantz8507-02-2006, 10:03 PMmy girlfriends aunt has a 89 SHO, the trans is bad in it. she said she would take 500 bucks for the complete car. im thinking of buying the car, and finding a decent mr2 shell and doing this.
ive been doing research on it, and it seems it would be worth the work and theres quite a bit out there for the SHO engines.
ill probably be doing this next spring Luni07-02-2006, 11:47 PMSHO engine is awesome.

The intake system on that engine is sick.

Long runners for low end torque. Short runners for high end HP and flow.

The engineering of this engine is astonishing.

As far as Im concerned its a better engine than most toyota V6s and much more performance oriented than ANY of them out of the box.

If you want torque, sure, go with a 3VZ or 5VZ but if you want NSX like powerband, and sound, get that SHO engine and see what can be done.

I think it would be an awesome swap. chuck07-03-2006, 12:34 AMits a pretty large motor though from what i remember...i've seen an NA fully built that was only a little over 400 at the wheels, i'd keep it toyota and do the solara 6 with the TRD-SC...but if you did the SHO it'd be something to be proud of too, unique for sure.

btw...SHO stands for 'super high output', i guess the ford engineers were feeling prettyin creative that day, hah PETC07-03-2006, 01:37 AMThe SHO is a Yamaha motor.

Yamaha also designed the heads on the 4AGE/GZE and the 3SGE/GTE

Two of the most succesful Toyota motors ever. So I think the SHO motor is just as "Toyota" as any other V6. Luni07-04-2006, 01:45 PMDont forget 1JZ/2JZGTE as well.. And the 2ZZGE.

In fact Im fairly certain any G head was designed by Yamaha.

And 400 to the wheels in an NA fully built? Thats ALOT from a little 3 liter.

That engine is awesome. Someone do this swap. canadam07-04-2006, 08:19 PM400 with a centrifigul supercharger. Weasy2k07-04-2006, 09:20 PMThe SHO is a Yamaha motor.

March 13, 2000
TOKYO - Toyota Motor Corp. is pulling Yamaha Motor Co., maker of motorcycles and performance automobile engines, into its fold.

Toyota will buy a 5 percent stake in Yamaha Motor from Yamaha Corp., which owns 33.3 percent of Yamaha Motor. Toyota thus will become Yamaha Motor's second-largest shareholder, at a cost of about [yen]10.5 billion, or about $100 million at current exchange rates.

TOYOTA BUYS STAKE IN YAMAHA In an effort to strengthen its engine development, Toyota will buy a five percent stake in Yamaha, the world's second largest motorcycle manufacturer. Execs from both companies said they will work together on engine development, motorsports and boats. The new relationship will allow Toyota to learn from Yamaha's experience in Formula One racing, an area Toyota plans to enter in 2001.


That is the reason why you dont see toyota making bikes, boat motors...etc... cause they invested in Yamaha to do that for them... canadam07-04-2006, 09:44 PMWell, Toyota's stake in Yamaha is much less than I had previously thought, I highly doubt that the reason they don't produce those things is because Yamaha does it for them. Plus... Toyota has a marine division :) guitar33307-07-2006, 08:19 PMIm a lurker doing some research on MR2s when I ran across this thread and I couldnt resist being a multiple SHO owner: Yamaha did make that engine and by what I have been told it is extremly relaible.
Yes, the 89-95 V6 SHO engine was designed AND built by Yamaha and shipped to Ford. All MTX (Manual Transaxle) SHO's got a 3.0L and all ATX (Auto) SHOs got a 3.2L for a bit more torque because of drivetrain (ATX) loss.

They are very reliable as far as the motor goes, the stock forged pistons are very strong and there are people running 11+ psi on stock motors (tuned right of course). My 92 SHO has 296k miles on the original motor, its my daily driver.

As far as power my 90 SHO is pushing 420whp/360wtq with a centrifugal supercharger (11psi, non-IC)

I'd love to see a SHO motor swapped into an MR2. The Taurus is a heavy platform for the motor at close to 3400lbs.

So I say go for it!

BTW this thread is worthless w/o pics; these motors even look AND sound beautiful. :love:
http://i2.photobucket.com/albums/y47/BuckChoklit/ford_sho.jpg Weasy2k07-07-2006, 08:28 PMJesus Christ that engine looks amazing....to bad there is a ford logo on it :(

Is there any block differences between the 3.2 and the 3.0 just wondering as far as the trannys go...

Adam apparently they have invested more lately but I haven’t seen any proof yet so I can’t say anything on that matter :)

Marine Division? I haven’t seen a single Toyota boat...or engine... guitar33307-07-2006, 09:28 PMIs there any block differences between the 3.2 and the 3.0 just wondering as far as the trannys go...
No block difference between the 3.0L and the 3.2L. The 3.2L has 15 extra ft-lbs on the 3.0L. It's popular to swap the 3.2L block (ATX) in a 3.0L (MTX) everything else bolts right up (heads/clutch/tranny etc).


Jesus Christ that engine looks amazing....to bad there is a ford logo on it :(
I know Ive thought about machining it off of there. ;) or engraving "not" before it. Not to throw it off subject but look how pretty the motors can be, heres my 92 mtx w/ 300k miles and my 90 mtx with a centrifugal s/c'er

I have a SHO motor now I need a car 1000+ less than a Taurus to put it in; MR2. Raptor13x07-08-2006, 12:50 AMIt is a pretty cool-looking motor. canadam07-08-2006, 01:42 AMGuitar333 , I'd be interested in talking about your engine a little more. PM me your MSN or AIM addresses :)


That's because you've never looked into it.
This is Toyota Japan's marine operation: Click Here. (http://www.toyota.co.jp/en/more_than_cars/marine/index.html)
Also, Toyota previously sold boats and even had a plant in the states under the brand name "Epic."

http://www.epicmarine.com/epicphotos/albums/userpics/10025/normal_Epic1.jpg

I believe all of the Epic boats were powered by the 1UZ-FE.

Marine Division? I haven’t seen a single Toyota boat...or engine... Weasy2k07-08-2006, 09:44 AMWell I do have lake front property and see HUNDEREDS of boats a day when I’m up there during a long weekend...that’s what i would consider "looking into" :P
Thanks tho that’s pretty cool!

I looked locally for the price of these motors and wow they are CHEAP....if anything the 3.2L would be a bit more but nonetheless a good engine. Its just a matter of finding out what tranny it will bolt onto. canadam07-08-2006, 01:10 PMThe boats are pretty rare, and have some little problems- but I still want one :D Luni07-08-2006, 03:00 PMSee the intake runner design? Check out the long and short runners.

That engine is so ahead of its time. Its awesome. Toysrme07-08-2006, 09:05 PMThe 89-95 SHO is equipped with a 220HP 24 valve DOHC V-6 manufactured for Ford by Yamaha, a handling suspension similar to that in the police package Taurus, better seats, and unique exterior trim. The regular Taurus and the SHO are as different as night and day, unlike most "family" cars with sporty versions. The SHO, though it no longer has the commanding lead in the sports sedan market that it did in the late eighties/early ninties, is still one of the most remarkable cars for the price available anywhere. Plus, you get to rub shoulders with all the nice folks on SHOtimes. :-)
http://www.shotimes.com/php-bin/modules.php?op=modload&name=News&file=index&catid=&topic=5




I wouldn't say it was ahead of it's time... The 4a-ge TVIS's had been around years before 89. The supra's 7m-ge had TVIS.

And if you think about it. How far advanced are dual path jap manifolds to begin with? It might as well be nothing more than a domestic dual plane manifold (which ahve beena round forever) just with valves at the end to completely cut said paths off!




I think the most advanced engines, way ahead of their time would be some of the Japanese faster bike / PWC engines of the early/mid 80's. Luni07-09-2006, 03:41 PMTvis is absolute crap compared to the system on the SHO engine.

Read up on it. guitar33307-09-2006, 03:53 PMSomewhere on Yamahas website they have detailed patents on the dual-stage intake manifold runner design. Its very interesting. It talks about the physics of it like the venturi effect. Weasy2k07-09-2006, 05:53 PMTvis is absolute crap compared to the system on the SHO engine.

Read up on it.

Yep have to agree with that one....the TVIS is a poor mans method of what the SHO has. Weasy2k08-10-2006, 05:39 PMBump....

Wondering... Toysrme08-11-2006, 11:10 PMWondering what?
The best of al of them is the newer ACIS system on the 1uz/3uz's. That's a super slick system that works. Weasy2k08-11-2006, 11:16 PMThats UZ.....this is v6 :) I wonder if i can find them for cheap around here (sho) Kanoodle06-06-2008, 07:40 PMI think the rotary was ahead of its time guitar33306-09-2008, 04:09 PMI think the rotary was ahead of its time
Did it take you two years to think of that response? :D jasenklems07-05-2009, 02:10 PMthere are some sho's that have better than 500hp on superchargers. xr4man09-08-2009, 09:09 PMi wouldn't even look at an sho engine in an mr2. only because it seems that toyota v6's just FALL right in an mr2.

now if you're gonna do a swap on a car that needs custom fab work for any engine swap, then yeah it would be a good candidate. such as this TT sho powered xr4ti.

http://i31.photobucket.com/albums/c369/xr4man/dsc00360.jpg 4v609-09-2009, 02:21 AMFord Sierra xr4.

Havent seen one of them for a bit. :) xr4man09-09-2009, 07:30 AMactually a merkur xr4ti with euro sierra headlights and a cosworth grille, but still a sierra based car.


and yeah that particular sho with the twin turbos is crazy bad ass. old school08-28-2010, 12:47 AMthese engines are quite tall. due to the design of the intake manifold.

just so you all know these engines were delivered to ford with a factory set redline of like 8500rpms! ford detuned the engines cause things like the a/c pumps and power steering pumps where failing due the the high rpm test they would run. everything i have read on these things tell me that they dont break and take boost in stock form like there is no tomorrow. And as far as i know the engines are all Yamaha. they just share the Vulcan bellhousing bolt pattern.

i was actually going to sell the one i have sitting in the garage as i have changed my mind on putting it in my 81 corolla. think i wil keep it for awhile as i am in the market for an mr2. never know.

peace ~dodge11-07-2012, 03:46 AMWhy bother? Tons of custom fab work, and there are so many better motors you could put in. If you want a 3L V6, there's Toyota V6's that are cake to install comparatively.

yamaha manufactures the engines installed in them toyotas :)
