alright i know the difference between the two but can anybody help me with wiring on it and what i would need to make it work right thanks.

 

HI welcome to the forums. Look at the top of this page and you will see the search button, handy lil gizmo can find just about anything you'd like. There is also the Frequently Asked Questions (FAQ) at the top of the threads list with much of the info you will need. And lastly there is the archives(bold letters above time slips and dynos) and has alot of useful write-ups and talks about just about everything.

Basically if you can think of it, it has been covered at least 60times or more. Best to search first, read, then ask a question about a specific question relating to your general question, rather than be flammed for not searching or reading the FAQ.

 

There are many differences between the two cars. If you want to convert an S4 to S5 fully, off the top of my head you will need to replace:

-all wiring
-engine, ECU, etc.
-complete interior
-all audio stuff
-lower control arms, sway bar end links
-front and rear bumpers, side trim
-taillights, mirrors

 

I think maybe he is asking for someone to come over and help him? Thats at least what it sounds like.

 

i just actually finished this swap and all u need on ur s5 engine is the s4t2 wiring harness and ecu, injectors, omp, front cover, and throttle body. also go look in rotaryresurrection.com all the info u need is on there..

 

sell the S4 and buy an S5.

 

but s4s are so much better






Head for the hills Ive started a war.

 

just to say would it be easier to just leave it as an s4 im gonna be replacing the whole motor but not sure as to which one i would benefit in as to power and what not .

 

well it would be easier if u stay withen its series...say u have s4 fc, it would be easier to get an s4 motor...but the s5 motor has i think 15 more horses which is not alot but thats the difference and also s5 turbos are better...
