04 rsx trans into 05 rsx body

[jackM]

Hey I've got a questions I haven't had a solid answer yet. I got a 04 rsx type S with a K20A2/K24A2 frank. the 04 rsx is rusty so I'm dropping everything into a new clean 05 rsx body. Do I just need the hondata adaptor since my trans is low frequency? Or do i need to send my ecu to hondata again for the 05-06 upgrade. Also what do I do about the speed sensor since the 05 harness has a different sensor than my 04 trans. I've also heard that the speedometer for the 05 is high frequency, can I just put my 04 speedometer and call it a day?

You will need to use the 05-06 Engine harness, and have the ECU modified for use in an 05-06 RSX with the adapter harness.
