Hey guys,

I just wanted to ask some questions. I did a lot of research and I think I've got about everything.

In order to get an s4 T2 into an s5, I'm going to need to use s5: ECU, wiring harness, Boost sensor, TB and TPS, OMP, Front Cover, and AFM.

While I'm doing the conversion I'm definitely going to put in the s4 drive train which includes the Tranny, drive shaft and rear end.


My first question, is the s4 drive train going to mate straight up?

and straight to the last question, is this all I need for the swap or is there something else I'm missing?? Will the connector from the s5 t2 wiring harness mate up to the connectors on the tranny??

Those are the two questions I have. If anyone can give me a quick reply, I'd appreciate it.

Edit: Also forgot to mention about the rewiring involved. I think I know what to do for that.
Thanks guys!!

the drivetrain is ok to hook up to.
The trans may need to splice some wires as the connectors are not alike from s4 to s5,but the sensors are basically the same function.
You will need the S5 Injectors as the
S4 injectors use a different connector(s5 is oval,s4 is square injector connector).
You are not in for nay big surprises the way that you are going about it,
It should be Cake for you!

Ok, Thanks a lot for the help

Also, What should I do if I were to use the N/A power steering and A/C?? Should I just keep the bracket off of the N/A motor??

Use the A/C and P/S off of your existing NA engine. It makes any swap much easier since there were also different versions of compressors and pumps over the years.

Chop the transmission plugs off if they're the wrong shape, and use bullet connectors for the switches.

I found the transmission connectors to match up perfectly, but they are farther back in the S4 T2 tranny so you will likely need to splice in a length of wire to get it to fit.

What about if you want to use a s4 t2 ecu is it posible what is the problem with un hooking the dash harness from the ecu. Is it only gonna affect my dash ( rpm ,oil etc)
