sho engine to lincoln ls body

[91Shonewbie]

Looking at putting a yamahammer and a Lincoln LS together but I'm stuck with the obdII problem for inspection not sure how that works or if it will work, if it doesn't then I'm done before I get started, if it will work any ideas how and what I might need to do. I already have the basic concept : engine and trans, the mounts, wiring harness, computer. But the emissions is going to be the biggest problem, cause 91 was not strick with emissions and the 2000 Lincoln LS is very strick I think. So Any input would be very helpful.

what you would need to do is get the obd2 computer tuned to the SHO motor. What would be involved is getting all the tables (spark timing, injector timing, etc. etc.) for the SHO pcm and making sure you could make all the needed changes to the obd2 pcm. That would be the only way to have a obd2 pcm control the car, since the SHO was never offered with obd2 from the factory.

the emission requirements for 2000 were more strict than the 89-95 ones, but the SHO motor was pretty clean so I think a decent running SHO motor would pass 2000 emissions requirements. You should be able to find out what the various requirements are for the years 1995 and 2000, and see how different they were. I do recall that a decent running SHO would put out 10%-25% of the limits for 94.

I dug through my records, and found a report on my red 94 SHO from 06:

HC limit 2.0, actual 0.31
CO limit 20.0, actual 4.84
NOx limit 6.0, actual 1.49

I found a report from my 97 TBird,
HC limit 1.20
CO limit 15.0
NOx limit 2.0

So, the 94 would pass 97 requirements, but I don't know how much tighter the requirements got by 2000.

That is some awesome info sense I was just looking at the emission standards chart, I'll be right back

 

[91Shonewbie]

Well I found it and it doesn't give the answer I was looking for,a it gives a standard base but no specific info pretaining to specific years. So I'll just have to decide if I really want to do it. In ny state (buffalo, where I'm close to) they plug in to the car, that is all they do and all other parts of the state they sniff the tailpipe.

Now same topic, because the LS came with the OBDII doesn't it have to stay obdII , this question is for inspection purposes. Gen1 connector I believe is EEC-iv that car is safety only inspection no emissions, the LS is OBDII with safety and emissions. But no tailpipe sniffer. I just answered my own question I think but love to hear Fed back. Ty.

Last question, Is there away around this issue?

how much of the LS would you like to work after this? be prepared to lose many creature comforts run by the canbus system integrated to the PCM if you don't keep the stock pcm.

if you want to retain OBD2 and the LS pcm, you will be looking at reworking the LS engine wiring onto the SHO motor. how hard will this be? is it even possible? hard to say exactly. i doubt its ever been done. for a reason probably. some guy pulled it off with a 5.0 windsor though, stock pcm. so who knows.

what trans you gonna run? the getrag 221 i assume? that would be easier.
because if you run the 5R55 you will NEED the stock pcm, as there is no aftermarket 5r55 controller available.

easiest route will probably be to rewire the engine and car to obd1 and run the getrag trans. use custom gauges and rewire everything inside the car you want to keep. AC, etc.
the legality of all that come emissions time will be sketch at best. i don't know new yorks laws. i could probably pull it off here in central MO, but the rules are different.

you've bit off a huge chunk here, hope you have deep pockets. this won't be cheap.

I don't know how it works in Buffalo NY - here they do a sniff test, and a gas cap pressure test. Here, a cel does not cause automatic fail, but I understand that some places it does. Here, if the obd2 connector is missing or non-functional, they just note that on the report but if it passes the other 2 tests you are fine.

So, if you have similar rules, then you could just leave the obd2 connector in the cabin but disconnect it, and run the engine with the SHO pcm (obd1). But before you go to all the work of doing it, make sure it will be okay to do it that way...

Far as I know no one has converted the SHO to OBD2 or ran it with an OBD 2 ECU but the Gen 3 guys who may have put a Gen I or II motor would know more about that.

From experience, I got the emissions done right before I swapped in the SHO motor into my Honda, 2 years later, the Honda's were so cheap, bought the exact same year and make and ran that through emissions. Even got pulled over for being loud, unless the
officer checks the vin, no one is gonna know the difference. If I was really serious about keeping the car, I would of taken the motor back out and put the original back in just for the emissions. But in the 4th year, the body started to look old, so I parted it out. Far easier than getting the OBD2 Honda with a SHO motor to pass emissions.

On a side note, why not a 4 valve Ford 5.4L? or a 4.6 terminator motor?

 

[91Shonewbie]

Yea, that's alot of info,thank you guys. the wiring would be a big job, the emissions is the other problem, the trans was still a concept in progress, I need more research to figure how to fit the trans to the engine, I was thinking of contacting Dana and see if they had any ideas or if they could manufacture or even attempt it and how much it would cost, the deep pockets at times aren't so deep and then at times they are bottomless, depends on the time of year. The legality is the issue really. Everything else is just time consuming, I use to be a glorified wrench turner, so doing the work isn't the problem, definitely alot of trial and error. If I decide to go ahead with this I'll try to do a post periodically.

this may help a bit with the OBD2 stuff

I can attest for American Motorsports knowledge and expertise in OBD2 tuning. They were able, over email and phone, to "tune" my '06 Taurus to function as a normal manual car using the factory PCM when I did my MTX-4 swap. They even got my speedometer to read accurately off of a Gen1 SHO VSS.

Pulled from my own build thread...Missed that.

Phoenix has a V6 SHO motor in a 2000+ Taurus, but I believe he runs the engine with the OBDI control system. His province does not have any emission testing, so that is not an issue.

Is your Lincoln LS a V6 with a Standard transmission now? If it is, it is pretty rare just the way it is, and adding a SHO engine will not do it much good in any respect.
The LS V6 is similar in horsepower (about 10% less), and on the other side, I doubt if the LS is lighter than the Taurus.
