I found a chromed s5 LIM and UIM with a modded TB, but it is for an S5 TII. I have an S4 TII, should I have problems with the swap? I think the TPS's are different and the manifold to engine ports are slightly different, atleast the gaskets make it look that way. I searched but all I found was jibber jabber.

 

you might have to do port matching to in order for S5 UIM to bolt on to an S4 LIM.
Im not sure about TPS

 

you have todo portmatch. Been covered several times. People say that the FD UIM is more worthwhile swap.

 

Who said anything about mating S5 UIM to S4 LIM..??


He never said that. Read.


Anywho, your best bet..

Swap on the S5 UIM and LIM, but use your S4 throttle body w/ TPS. All throttle bodies are the same..so it is a direct fit.


:-D

 

thanks adrock, The S5 tb that comes w/the manifolds is modded, so I would like to use it. Could I put my S4 TPS on it and use the S5 TB?

 

You could just snip the wires off the narrow range TPS and put the S4 connector on there, then if you have an SAFC/ETC you can wire it into the full range if you wanted. Keep the S5 TPS either way.

 

S5 throttle body has no arm to use with the OMP but if you have it eliminated then that is no problem, you already mentioned the TPS.

there is the EGR port in the middle iron you will have to worry about with this swap.

the FD anything is not an easy install, don't bring that up here because it is hardly worth it IMO aside from looking cleaner the port matching would have to be done very well for it to outflow either the S4 or S5 manifolds.
