I basically plan on having my engine rebuilt or replaced in the next year since I don't know how well its been taken care of so I am looking at my options. If I got a jspec I figure I might as well go with the 200hp one Now what would I need to do this swap? Just the S5 ecu or what? How hard would it be to do also? Would a shop charge big money to do this or basically the same price as a S4 engine install? At corksport I can get a S5 jspec for $1200 plus shipping with will more than likely be a few hundred dollars. But I get a better turbo/manifold plus the 18 extra HP in a lighter car won't hurt. Please let me know what you think I would need, thanks.

 

you also need the harness

 

I would assume all of the sensors and such would need to be S5 or aftermarket.

 

if you have a s4 already, i would recommend useing the s5 block, manifolds and turbos, and using a s4 front cover, throttle body, all electrical compontents ect. so basically you're using the s5 block and turbo and manifolds. the reason for this is that i like the omp system from a s4 and the lighter rotors and bigger intake ports and better desinged turbo and manifold from a s5. not sure how much it would cost to do at a shop, but it's not hard at all. you got the forum to back u up. you'll appreciate your car ALOT more too.

 

Ya I got the S4 now, its runs smooth and everything(though it seems slower than it should be). I just figure the engine will go at some point and I always like to upgrade things when replacing them. Then you end up with the best of everything by the time you replace everything. So what I need is the ecu, wiring harness, and what sensors? I like your idea flying but right now I want to know what I have to have for the future, but will definitely see if I can do use the S4 omp once it comes down to it. Thanks guys.
