Title: SWAP from S5 to S4
Post by: McPie on August 28, 2006, 10:29:58 AM
Hello all,
 
I have two cars:

the other one it TII full of rust but deam good engine:Viking
http://mcpie.fotopic.net/c991527.html (http://mcpie.fotopic.net/c991527.html)
 
I want to put everything from S5 to S4 also to install FD LSD Differencial.
 
I want to ask if some did that before what should I know about swap like that. Do any one has fotos or other type of info?
 
P.S. I\'ve lookd and found anywhere same thread  :o

ok yes it can be done

now you have two options - you must decide which way is best for you.

1. Remove all aternator / manifold / turbo / loom - i.e anything attached to engine and then swap these between s4 > s5 engines. then you wont have to worry about wiring so much. this method basically fools s4 ecu into thinking it is s4 still but has s5 block - apparantly it runs ok? but i am not convinced.

2. this method you dont have to change over engine ancilaries. you swap engines (it is a very simple job really) then you must tie s5 engine loom to s4 this is a where the transplant gets difficult. you change over your s5 ECU into your s4. if you go this way let me know then i will send you some wiring diagrams.

if you choose the second option then let me know buddy.#

can i have the instrument cluster from the red car please!!!

propably I\'ll swap engine with whole wiring and put S5 ECU into S4 shell
 
As I understoot I choosed 2nd option.
 
What do you mean
"can i have the instrument cluster from the red car please!!!"

good choice. as i think it would be impossible to take everything off the engines and not expect something to snap / break!

i was looking at the pictures of your Red t2 - i want those white dials you have (speedo) thats in the red T2!

is the yellow mazda a t2 or an EGi?

Post by: McPie on August 29, 2006, 12:24:08 PM
yello EGI as I said yellow is empty. I take everything from s5 red shell and install into yellow s4 shell :)
 
that should take a litlle time :D I also have greddy e-manage attached to my TII. so engine gearbox driveshaft TII ECU TII wiring and all stuff will be placed in to yellow shell ;)
 
those white are ugly :D simple paper sticked to spydometer and tachometer :D
 
if look form far few it looks nice , but look a little bit closer it is peace of **** :/

LOL nice one buddy - it had me convinced!!!!

anyway - i have the diagrams for t2 into egi i think -

you have to mate - engine loom to chassis loom as existing s4 chassis loom will not fit onto t2 ecu.

if you transfer ALL wiring then that might take VERY long time as wires going all over the place!

here is the diagram i used along with FSM for both cars, i assume you already have the factory service manuals.

the emissions harness is the plug right up the side of the  dash on the side "kick" panel. your injectors get power from here.

the engine loom stays attached to the engine just thread it through the firewall.

if you need to know anything else then post here.

also in parking made some test it perfectly drift and draw sun :D
 
there is one problem no RX is without muflers and exhaust ends where lsd starts, so it getting very hot and pushing away oil from it :-/
 
soon will make new exhaust system
and make some upgrades for my diff including oil radiator
