What do i need to change from my S4 TII engine to make it fit into my S5 vehicle?

1Revvin7 03-03-2003 08:44 PM
s5 wiring harness and injectors, or s4 injector connectors. That should be it, but im not too hot with the wiring bs changing, another reason i went the route i did.

JDM rx7 turbo II 03-03-2003 08:45 PM
what about the other connectors that the harness provides

Don't you need to wire the knock sensor differently?

Use the s5 sensors, rats nest and ecu/injectors. Also swap the front cover to use the s5 front cover and elec OMP, with out that, the ecu would go into limp mode and not work.

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.

JDM rx7 turbo II 03-04-2003 12:07 AM
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 ?

Geoffman72 03-04-2003 03:34 AM
Can't you take the engine back? The S4 NA engine wont make as much power as the S5.

vosko 03-04-2003 10:04 AM
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?
