2jz Ls

I dont beleive so, i can fab most of the parts myself. For the ones i cant, i have friends who can. Trust me it will cost less then 2g's easy. I wouldn't be atempting it otherwise, as i dont have deep pockets.
 
Plainless can make a harness to run what ever he needs to run.... aftermarket gauges and so on... and the supra harness is going to run the Engine side of it...

I cant believe i have to explain this to someone that knows so much... Anything CAN BE DONE!

your acting like im having him rung a TOyota 2jz off a Lincoln PCM.. come on man! think
 
I have personally used a painless wiring system before, top notch stuff.

however your advice is not on point - meaning it's really not advice.

I have not yet seen you 'explain something to me'....
 
Becuase if I have to explain it to you .... you probably wont understand.. so i'm not going to waste my time.. ANYTHING can be done... If he really wants that 2jz in his LS... I'm sure painless would have no problem helping him... at a PRICE...
 
As I've said somewhere here before, I know of a case, long ago, where a guy put the engine from a P-51 Mustang in a '29 Ford sedan. He drove it on the street, at least a little bit. The engine was so big, he had to sit beside it. Anything's possible. That doesn't mean it's the least bit practical. There's more work, and cost, to cross-breeding a 2JZ into an LS, than to building an AJ engine to put out 1K+ of power. So, what's gained?

jerry, im going to install a series of levels in my apartment, with steps

empire, i wish you the best with this project, but some of the people here know what theyre talking about when it comes to major mods for the ls. people have tried and spent thousands without a whole lot of success. as somebody pointed out in this thread, ford couldnt get the ls running for too long with another ford engine.

again - useless post.

He startred by asking for advice and help - where is that found in any of your posts?

This genius just said that Quik wouldnt understand somthing on the LS! :lol: :lol: :lol: :lol: :lol: Hes forgotten more that youll ever know about the LS!
 
oh heck - I still learn lots from others - and it's good to see projects that are different.

I don't mean to sack-ride lincoln00 - it's just not real advice.
 
yea i talked to a guy over a 2jzswap.com he said i should be able to use there signal interfaces to continue to use my factory tach and speedo. He is going to do more research on the LS wiring and call me back.
 
Thanks Quick and gt95coupe for the sites i will be trying to get intouch with them within the next couple days...Thanks Again..
 
No I don't think YOU understand. EVERYTHING electronic in the LS is connected in some way or another. If you remove the gauge cluster half the electrics in the car stop working. I know this because I've had mine out to replace a few bulbs. None of the windows worked, the locks wouldn't work, radio wouldn't work. You'd have to rewire the entire car to make it work. That or find out a way to integrate with the LS' computer system, which even Ford couldn't do.
 
Actually i do understand...pretty well actually...only thing i just said was that he beleives i can continue using the factory spedo and tach. I said nothing of windows, window locks, or anything else for that matter. I am already aware i have to rewire all these things to keep them functional.

That's the point. When the Lincoln/Ford engineers put the 4.6 from the Mustang into the One Lap LS most of the electronic stuff didn't work; speedo, tach, a/c, windows, fuel gauge, etc. EVERYTHING electrical (which includes the speedo and tach) runs through the FEM. Take that out of the loop and nothing else will work.

From a Ford engineer:

The network in an LS speaks "SCP" which stands for Standard Corporate Protocol. In otherwords, it's a proprietary network standard, so you're not going to have much luck with any standard type of communication. You're best bet would be to attempt to reverse engineer an NGS. In the future, more and more Ford products are likely to start migrating toward CAN (Controller Area Network), which is a standard protocol (PS, this is just speculation, I'm not involved with in-vehicle network applications). At least then you'll have a better chance of finding some software to start with. The 2003 LS is the first Ford product to use CAN (other manufacturers use it already), but only for powertrain diagnostics. Everything else still speaks SCP. It's a step in the right direction, but a baby step.

The 2003-2006 LSes do use CAN. The only way this will work electrically is to re-do the entire electrical system. Even then I would be the airbags wouldn't work. You would probably also lose ABS and traction control. You would end up with a 2000 bodied car running on a 1960's electrical system. Again, DEEEEEEEP pockets.
 
I gurantee that guy does not know the LS well enough. The only way this will work is if you use everything electrical and all the computer stuff,..etc,..etc from the Supra from the gauge cluster all the way down to the smallest of sensors. Basicaly you will have a Supra with a LS body and interior and that is it in the end.


Its not rewireing that will in the end be the issue its basicaly the damn programing! There is nothing you can do to use the LSes computer and have it register these parts and there is no way of using the Supra computer and have it register all the LSes parts.

Yep!
 
Again i understand the FACT i cannot use the factory FEM, or any of the factory lincoln wiring. Im not sure why everyone continues to try to make this point. I am talking about using a supras ecu to get the tach and speedo signal, and using a signal interface to run the factory cluster (HOPEFULLY). I am not talking about or considering the idea of some how marrying the 2 ecu's together to work in harmony. That would be litteraly impossible. I am only trying to figure out what can be rewired to work and what cannot. I am only trying to see how street-able it can be made. I have built many cars and done many motor swaps in the past and i know somethings will be lost in doing this...So please do not continue to tell me these things!
 
EMPIRELS - are you trying to remain street legal or is this a track only?

You contradict yourself here. An interface IS tantamount to marrying the two electronic systems together. There is NOTHING in the LS that can be re-wired to work correctly. The speedo (instrument cluster) gets it's information from the FEM, through various sensors. The cluster won't recognize the information from the Supra's ECU. The programming of the Ford ECU is proprietary, ergo the reference above to reverse-engineering the programming.

What components EXACTLY do you want to work?
 
The guy over at 2jzswap.com told me this "Unfortunately the stock gauges will not work, since there is no way to convert the sending units to match properly. The upside is everything else should be able to be used, power windows, a/c, etc"
So that is some good news...
 
one of the big issues will be the SRS system - it's technically illegal to remove it - and not sure how you would integrate the existing setup into a different computer since all the inputs go into the PCM and it determines when and what to fire....

The other issue is emissions. Again technically you are not allowed to swap in an engine from an 'older' emissions grade into a newer car.

The other silly things like ABS, TC, ..etc will simply be easier to remove than try to re-wire.

But if you do not have emissions testing or annual inspections in your area - it a moot point. Unless your insurance as issue with it - something to check (don't ask me how I know)

The LS uses a negative switched system - meaning that most everything has 12v hot running to it and the PCM completes the circuit to ground to enable. This is common with euro cars - not so common with Japanese or US (my supra use a switched hot).
 
I've seen a swap into a IS300 which apparently is a lot harder than everyone thinks. You basically needed to fab up custom mounts and such even though the motors are similar.
