S5 Turbo Swap.
i have a question about JDM S5 turbo swapping it into the S4 model. I bought a complete JDM S5 Turbo w/ harness, ECU will it direct fit into the S4 model? Do i have to change the JDM harness into the USDM one to make it work? Or do i have to swap everything from the S4 onto the S5 engine to make it work? Also how to i wire the key ignition onto the S5 harness to make it start?

Sell the ECU and loom. Using S5 electronics in an S4 will make the swap much harder. Using a RHD loom in a LHD will make the swap much harder. Doing both is sheer lunacy.
Keep the S5 intake manifold and turbo/manifold set-up, but use an S4 TII EFI system (ECU, loom, injectors, sensors). If you want a functional OMP you'll need to use an S4 TII front cover and TB.

i just got done finishing this swap and what u need is an s4t2 usdm harness, injectors for that harness, s4t2 ecu, s4t2 throttle body, s4t2 front cover, and s4 omp...and everything else is straight swap...

Connecting the stuff back to the cars wiring harness is the hard part. Boost is different on an S4 and S5 so you will run into issues there along with who knows what else if you try to ghetto rig it, so go with the S5 ECU or go with a standalone. Or you could just drop that engine in and use a S4 Throttle body on it and hope you get it to work.

i forgot to mention u use the s4 boost sensor and the s4t2 afm if you use the s4t2 harness...go look at rotaryresurrection.com...i fallowed waht he said and it worked....

is it possible to use all s5 turbo stuff in a s4 model? cuz if i'm using all the old s4 stuff then why bother to buy a s5 jdm motor right. i bought a complete swap, like i said, full jdm motor, w/ harness, sensors, ECU. is should just be a direct swap all i need is to extend the harness make it fit. am i right?

get rid of the harnesses all together, and the ECU and get your self a standalone system and just be done with it. Thats what I will be doing. Still trying to decide which one to go with, i was going to do the haltech but it requires a PC with DOS for tuning from what I can gather. I was looking at some other's that will run on windows based PC's. Seems to be the way to go. But you do whatever you want. The engine management just seems to be a very small price to pay for the options you will have.
But yes other than extending the wires you should be fine. I would imagine the interior under the dash connections may not match up. Especially since that is all s4.

Just get a standalone system. Things will be cleaner, and the advantages should be obvious. That part is expensive though... if you do decide to go Haltech, Check out the Haltech section of this site, and contact one of the vendors...(cough CLAUDIO, cough...)
The E8 runs off Windows, for what it's worth. I am using Windows XP to work with mine. I plan on getting Vista in a few weeks, and dual-booting both OS's and seeing if Halwin is compatible with Vista.

u could either go to what there saying on top about standalone but if u dont want to listen to me about using the s4t2 harness then u will end going through all the bullshit wiring for the s5 harness to fit with the s4....u could of gone with the s4t2 motor to make it a straight drop in but instead u got an s5 just like me and that is y im telling u what i had to go through....

I'm saying that the series five EM harness won't just plug into the series four Front harness. Whatever. It can/could be done but I've yet to see someone write up the pinouts/adjustments for novices. Well, I take that back. There was a fellow from the Czech Republic that did something like that. A friend of Higgi's. Can't remember the name right now. Something like Lucius with a $ sign in front of his name.
If I had a series five engine/turbo/transmission...............I'd use a series four ECU and the EM harness that is presently in the car. It's so much easier. Even then you'd have to make some minor harness adjustments. Plus a series four boost/pressure sensor/afm/stuff. I'd premix til I found a series four front cover as far as the omp goes. I'd NEVER premix on a permanent basis. EVER.
A engine is an engine. Four plugs, afm, boost sensor, four injectors, water thermo sensor, airintake sensor and all located in the same ole place. That's my broad view of series four and five engines.
