plug & play???
so i have an s4 n/a and i bought what i thought was an s4 TII but it turned out to be an s5. i got the motor tranny, wiring harness, ecu, pretty much everything except a downpipe and blow-off valve. my question is...can i just get an s4 TII intake manifold and everything that goes along with it and an s4 TII ecu and it'll be for the most part plug and play? If i do this, i'll probably need a knock box right? any help on this would be greatly appreciated. also if anyone knows where i might be able to find an s4 TII intake or downpipe, please let me know.

F**K THE SYSTEM!!
If you get an s4 ecu you would have to change the oil metering pump to an s4. might have to change the whole front cover actually...
s5 ecu control s5 electric metering pump. s4 ecu doesnt do it cause its mechanical on the s4.
If the s5 wiring harness isnt cut. then use it along with all the s5 required parts such as s5 turbo MAF

You've a series four car.
You bought a series five engine/transmission.
A series five ECU and series five EM harness won't come even close to mating with a series four n/a Front harness.
Cheapest way to make this work is to throw away the series five harness and ECU. Buy a series four turbo ECU and keep your n/a EM harness to put on the engine. There are minimal wiing changes to be made to a na EM harness vs buying a series four Turbo EM harness and trying to use THAT. The front cover has to be changed to a series four turbo front cover OR ugggggh! pre mix (sucks eggs).
YOu still need things like series four boost sensor/afm, turbo transmission mount and other stuff.
