is this possible? and willthe wiring harness from an s5 work as well?

 

posible, but stupid as ****, just get a custom made one and be happy, there is no reason to use a NA one at all.

 

If you were us, you think you could understand that?

 

i now have a t2 for my 89 gtu. i have the motor only, and it is missing the UIM. i have several UIM's from s5 n/a's and such...will one of these work? hows about the MAF? also, what do i need to do to get this working, can i use the wiring harness from the gtu and jsut run a boost controller or something? i have no idea what im getting into, ive built an mx3 before, and a couple honda's, but im fascinated with the 7. any and all info will greatly help. thanks

 

Honestly, why not just trade/buy the parts you need and make life a hell of a lot easier on yourself?

 

a non turbo intake manifold will not match up to the ports on a Turbo motor.

And non turbos and Turbos use different wiring harnesses and ECUs, so no you can't use a non turbo harness and a boost controller, unless you want to make a custom harness.

 

i woud hope you would understand it.....all im asking is if there is a way to use the s5 wiring harness to getthe turbo motor running. and where do you find a custom UIM?

 

Threads merged. ONLY start one thread on the same subject. No multiple threads by the same member on the same subject

 

U can use the NA harness, but u have to modify two wires, i don't know witch ones thow.. Like someone mentioned sell your spare NA stuff and buy a TII UIM, eather ebay or the classifieds in the forum here.. Use the search function to find how to modify the NA harness.

o yhea u will need a TII ECU too.. U can find them in ebay or the classifieds in teh forum. YOu can use teh japanes spec one.. I think thats about it...



Good luck

s-5 Non-turbo and turbo use the same harness.
not sure about the s-4's.

the only difference is you have to run a knock sensor wire to the ecu.

if applicable.

 

Ah I guess that is why the engine harnesses have different part numbers and pin layout on the ECU.

The dash/body harnesses are the same... its the engine harnesses that are different, and as mentioned by even yourself, you would need to customize the ENGINE harness to make a non turbo engine harness work for a Turbo.

And FYI, the S4's use different engine harnesses as well, depending on if the car is convertible, coupe or turbo.

Now you could make a non turbo harness work, you just have to add and extend wires- hench the custom harness thing.

 

awesome, thanks guys, that is useful information. i will have to modify the harness.....and there is no luck on the UIM?

 

Turbo engine is a 4 port engine while the NA is a 6 port, so yah...

lol nah, My **** worked fine. Don't really care what the engine harnesses have different part numbers or not.. I didn't customize mine. Full turbo swap, on the stock s-5 N/A harness. I didn't use my knock sensor. Pulled it out of the block and did no wire customizing... Everything fit's on right, no problems at all. With mutiple cars/harnesses...

 

Your problem isn't the harness, it's like what everyone has been saying, they won't really line up with out some massive modifications to the manifolds.

 

For sure. The S5 N/A harness works fine on the a S5 13BT engine. If you want a knock sensor, you'll need to run a extra wire. Besides that, it's pretty much plug & play.

Perhaps you should do a search on turbo swaps. The questions you're asking is just the tip of the ice burg in regards to all the work needed in order to correctly complete the swap. Oh, no go on the N/A UIM.

 

there is only one thing missing, the poster didn't mention if this was a S4 or S5 turbo engine, that would turn this whole thread upside down.

 

well, the N/A upper intake manifold, isnt going work anyway..

s-4 on s-5
s-5 on s-4

none of that..
