in this thread it looks like they managed to get a 02-04 ECU to work on a 05 motor. is it possible?

The difference between the 02-04 and 05 RSX is the ECU, vehicle wiring and transmission. The engine is the same, so using a 05 short block in an 02-04 RSX doesn't change anything.

thanks for the prompt response.

i'm not sure if i'm reading it correctly, the 05 block is backwards compatible with 02-04 components starting from the 02-04 block wiring and all the way through to the 02-04ECU?

it is not the same the cams are type R. In that post, the kid says he knows for a fact now that the head was also replaced, meaning he got the cams too. With his setup(i/rh/e), and that motor with K-pro, he can make about 235-240 whp. He got hooked up

Well the cam serial numbers for the type r match those of the 05 type s.
