As the title states, how difficult is it to swap an S5 engine into an '86 coupe? I've read there is a lot of differences between S4 and S5 when doing a swap, but I have the S5 engine+transmission+wiring harness. Is there anything major I should be concerned about? Thanks.

Also, engine /w wiring is all JDM going into a LHD car.

 

Let's ask you some questions.
Like is the S5 engine a TII engine?..,as they did not make a N/A JDM engine.

 

Yes, it is a Turbo II engine, with the stock Hitachi turbo. I have everything that would've come with a front clip cut off right around where the steering wheel is.

On an unrelated note, the car had GReddy and RE?? all over it. I thought I was getting an aftermarket turbo, lol.

 

Bumping because no reply. Also are there any parts off my S4 N/A engine I should swap over? Thanks.

hi from ross in nanaimo. yes you can put the s5 into a s4 but read all the changes that have to be made. especialy the electrical wiring harness to the body harness. I DID IT and when they say use the s4 na harness , that proved to be the better choice, that i should have done . i did install the s4 one but changed my mind and redid it with the s 5 one, have had nothing but extra work, and the oil metering pump went,so i am premixing anyway. I will go with my n 333 ecu s4 next time .
