so i need a s5 harness, ecu, omp, front cover, rats nest and injectors..



can i use any of these of my S5 N/A engine ?



i can get the harness, i got a ecu. i am missing the rest.

Mike, what about the tps braket, I guess parts of the throttle body linkage have to be swap or can the whole throttle body swapped. S5 have a dual tps compared to the s4 which has only one.

If you have a s5 TII you have everything u need. You can't used the na sensor. mayb ejust the coolant and air. but that's it.

well i bought a engine from a performance shop around my way. they sold me a s4 engine.



my car is a s5 N/A



i wanna convert the s4 into a s5 so it will plug into my main engine harness.. get it ?

Can't you take the engine back? The S4 NA engine wont make as much power as the S5.

JDM came by my house last night and compared harnesses. i figured out for him. that he has a S4 engine and NOT a S5 like he thought. i personally would sell the engine and get a S5 . or use the S5 and buy a haltech E6K and bring it to a shop

you can either swap t bodies, or maybe make a bracket?
