914-SHO Project Thread

914 SHO Project Thread

I have a project that I'm working on which will utilize the 92-95 3.0L, and I have some questions about the upper intake manifold and runners.

I thought I read that the upper manifold can be rotated 90deg for optional installations. If this is so, can it also be rotated 180deg - placing the air intake on the other end?

I've also read some posts about porting the runners, but I'm curious what the material is. If I had to guess I would say cast aluminum, but I'd like a definitive answer.

TIA,

Gerard

 

well, 180 can be done if you slice off the top of the timing belt cover and purchase some intake spacers from Off Road SHO. 90 degrees....well, things don't really line up all that well.


As for the material of the manifold, you are correct. It is, in fact, cast aluminum. I hand ported my runners, and while I removed a fair amount of material, I think the biggest gains came from cleaning all the accumulated crud out of it.

 

It seems everyone is putting a YamaSHO is something these days, but no one is putting any exotic motors in the Tauri.


I wonder why?!?

 

For the 90 , not impossible , but pretty close. Unless you turn the whole motor for th RWD setup , I wouldnt recommand it , it would require a massive adaptor fabricated from scratch.

Heres a pic of the heads , where the intake sit to help you better understand what you will get into , the 180 will also require some re-wirering. (if it ever sits properly.)

 

turn intake 180*
add phenolic spacers under it
notch the timing cover
remount the CPS someplace that its well grounded (very important)
rewire tps and iat

 

Don't you mean the DIS?

 

thanks, lol

 

Thanks for all the feedback. I'm certain that it was an article I read that indicated the 90deg rotation. Perhaps it meant not only the upper manifold, but the lower one.

Once I get to that point, I'll be sure to share my findings.

Enjoy!

 

ummm, no.

The lower intake is not going to rotate 90º either.

 

the intake only rotates 180*, thats the only option

you can go it by either:

a: pulling the surge tanks and slapping them back on the other way around
b: pulling the entire intake off the heads and spinning everything 180*

both techniques have the same effect, as each set of runners are all exact clones anyways

rotated 90*

 

Yeah...might have a small vacuum leak with that setup...

 

but luckily vacuum is only good for fuel economy, and the less vacuum you have the more power you make, cause vacuum is formed via restriction

so by that logic, i should have MORE horsepower with this setup ...

 

Ummm.....u mean NO horsepower! :laugh_ti:

 

well, since we're talking about a Taurus, horsepower doesn't mean a damn thing. Bullpower, on the other hand.....

 

Bullpower.....lol
My friends are gonna think I've lost it completely now.

 

Thanks guys.

I was able to search and find the article. It was at Answers.com. I've posted a section of it here for reference.

In the mid 1980s, Ford Motor Company worked with Yamaha Motor Corporation to develop a compact 60° DOHC V6 engine for transverse application. This engine intended was to power a mid-engine sports car, but that project (known internally as GN34) was cancelled. Instead, Ford decided to place the engine, dubbed the Super High Output (or SHO) into the front wheel drive Ford Taurus sedan.

The SHO engines share a common bell housing pattern with the following Ford engines: the 2.3/2.5 L FWD HSC I4, the 3.0L FWD/RWD Vulcan V6, and the 3.8 FWD Canadian Essex V6.

Due to the engine's unusual and aesthetically pleasing appearance as well as its compatibility with common Ford RWD transmissions, such as the AOD and T-5, it is sometimes transplanted into other vehicles. The distinctive intake manifold is bilaterally symmetrical, so it can be rotated 180 degrees (making it face "backwards" on the engine, relative to its original installation orientation) to ease the engine's transition from transverse to longitudinal mounting.

THe article states this is a compact 60° DOHC V6 engine. Would any of you agree with that? I've heard others state its unusually tall. It sure would be nice to find a source of detailed info like cross-sections, cut-aways, etc. It would make these custom applications less like trail & error.

Enjoy!

 

its definatly compact relative to how they did stuff 10 pounds of engine into a 5 pound space, but like i said , relative ...

the engine is just about cubic in shape, as long as it is wide as it is tall, measurements can be found in the thread about the engines measurements, a number of people (including myself) all contributed different measurements to said thread

cut aways of the head are also available, but i forget where, im sure someone else can chime in about that

 

Tom, you're on!

Yes I am trying to put an SHO into a 914. I have a 74 that I want to develop into a custom 914, and the SHO engine is just what I'm looking for performance wise. Now if I can only get it to fit.

I'm located in Phoenix. Shoot me an email and we can set up a time to meet.

Here's a link to my Progress thread.

And a pic of the donor car.


Hotrod - thanks - I'll search for those measurements in the meantime.

Thanks,

Gerard
