A little bored so i decided to make one since a lot of people ask if it's possible to swap an s5 t2 into an s4 chassis, and yes it's pretty simple if you have the common sense to do it.

Ok, let's start on what you need.

S5 T2 engine (JDM or USDM)
S5 T2 or NA wiring harness (JDM or USDM)
S5 T2 block off plates
S4 NA wiring harness
S4 T2 ECU along with sometype of piggback (SAFC, Greddy Emanage, etc.) or standalone (rtek, megasquirt, PFC, etc.) (N332 or N333)
S4 T2 throttle body and tps
S4 T2 boost sensor (N318)
S4 T2 throttle cable
S4 alternator
T2 Hood
Bigger fuel pump (FD fuel pump, walbro 255, T2 fuel pump)
Downpipe and Exhaust
Boost gauge
Blow off valve (only if it didn't come with one)
Pinapple racing OMP Plugs

Once you have all things above now you're ready to get the started

First start with the obvious things like drain all the fluids, disconnect all connections from the engine, remove hoses and so forth. When removing the engine harness, make sure to fully take it out of the car rather than leaving it in the car while i pulled the engine out of the car. Can cause this to happen .

With the engine out of the car, go to your new/used turbo engine and start removing all the emissions and OMP. Then remove the OMP injector and use the OMP plugs to block them. Now plug up all the plugs where the vacuum lines used to be with vacuum caps. Once thats done attach longer fuel hoses to the fuel rail. Now the engine is ready to go in the car.

Note: JDM fuel rails run backwards so the fuel filter side of the hose goes to the secondary fuel rail and returns from the primary fuel rail to the return line.

Before getting the engine in the car, make sure the engine bay is free of all the emissions crap (charcoal canister, cold start bottle, useless vacuum lines, etc.). These tend to get in the way of things. Also please clean the engine bay of grease, if you willing to do all this work atleast clean your damn engine bay. Anyways, check if the motor mounts are still in good condition. If not you can always get new mounts or since this is a budget swap you can get hockey pucks as motor mounts but i do not recommend these cause of the tendency to break if you choose to further mod your engine.

Now that the engine is in, now it's time for the wiring harness. You will need you old s4 wiring harness and a s5 wiring harness. Does not matter if the s5 is turbo or na. Swap out the s5 injector clips and solder them to the s4 wiring harness. This makes it so you can actually plug in your wiring harness to the injectors. Once that's done, with the s4 na afm you will need to adjust the spring tension to prevent the car from running overly rich at idle. You also may want to port the t2 throttle body since there are no emssions on the car and remove the secondary butterflies on the tb.

Note: The white plug on the emissions harness must be cut and soldered to the knock sensor wires. This way so you can use power steering with having the car retard itself by about 20 degrees whenever the power steering is activated.

Now plug the wiring harness to the engine, swap out alternators, plug in ecu, connect piggyback system, put in all the fluids needed and a little bit of 2 stroke oil in the gas tank. Do your final checks see if everthing is plugged in and fluids are in the engine. Now start it, it might take a few cranks to get it started. The fuel pump needs to prime and pressurize before it can actually start.

I left some things out cause there pretty much self explanatory.

now a short video of the first start up. I used front mounted intercooler setup cause I didn't have a t2 hood at the time.

Also since this was a budget swap total cost came to about 2000-2200 that's including the engine, new exhast, new parts and other misc crap i bought lol.

Please feel free to add, correct or even more simplify what i did. This is just an outline of what i did pretty much.

 

So your running a s5 13bt in a s4?

 

not bad

 

how much did it all cost?

 

read.

 

yea

my grand total including the engine, misc parts and fluids. 2158.72

the engine was 1800 shipped from japan2la which included the jspec harness and ecu. it came with a dual alt pulley which was pretty awesome

 

It's great that you were able to scrounge the parts for such little money, but it isn't a realistic planning price for most people.

 

I guess not a lot of people tend to keep their emissions with this sort of swap although I figured most people would keep their OMP.

What transmission are you using?

 

nice...

 

i agree, this is just if you want a running car that'll get you from point a to point b but it is a start.

you can always swap out the front cover for an s4 one and use the s4 mechanical omp but that's on person if they choose to.

i used the na trans and diff then upgraded to the full t2 driveline not too long after that. i just needed a car to drive to work and back.

i figured if aaroncake can run the bridgeport 6port with the na trans and driveline i figured i take the chance and do the same. it did take him about 2 years (if im not mistaked) to destroy the original transmission.

also i dont recommend launching with the na driveline for obvious reasons lol

 

I am talking about your parts list vs. your pricing.

2158.72 grand total including the engine, misc parts and fluids.
-1800 engine
= 358.72 for everything else

Besides the engine, your list included:
S5 T2 or NA wiring harness (JDM or USDM)
S5 T2 block off plates
S4 NA wiring harness
S4 T2 ECU along with sometype of piggback (SAFC, Greddy Emanage, etc.) or standalone (rtek, megasquirt, PFC, etc.) (N332 or N333)
S4 T2 throttle body and tps
S4 T2 boost sensor (N318)
S4 T2 throttle cable
S4 alternator
T2 Hood
Bigger fuel pump (FD fuel pump, walbro 255, T2 fuel pump)
Downpipe and Exhaust
Boost gauge
Blow off valve (only if it didn't come with one)
Pinapple racing OMP Plugs
fluids

It is not realistic to plan on only $358.72 for the above items, even if you buy them used. Sure, it is possible, but highly unlikely that others could get a deal like that. Most people would pay about $1,500 to $4,000 for the items on that list.

the red is what it came with or i already or i made it myself. but it is somewhat a realistic price depending on your knowledge. i was a broke *** college student and had a budget of 2500, so i guess it's not all knowledge. it depends if your broke too lol
