hey im wondering if its possible to swap in the s4 bi turbo engine into a b5 a4?
i tryed searching but it isnt working.

 

im sure it would fit, anything like this is possible pretty much with a car, it might just be way way way too much money or hard work to do. What year of A4, i think the S4's are drive by wire not drive by cable like some of the earlier A4's. and you would need new ECU, mounts and all that good stuff, plus labor.. unless you are stuck with or attached to a car, it miught be better to just sell and get an S4

 

sure it will fit but imo sell the a4 and get an s4 because the cost isnt worht it

 

the amount of work would just be ridiculous, sell it and buy an s4

 

Go for it.

 

buy an S4, debadge it. and throw 1.8T badges on it. problem solved.hahahaha
