this is another one of your noob questioons...

i was reseraching hondata about the reflash and the kpro and i came across the different engine code for the rsx...

k20a2 - 04rsx-s
k20z1 - 05-06rsx-s

...i just recently for my 06 rsx-s and i thought i had a k20a2, and i was wondering what is the difference in the engine between these two...

any info would be greatly appreciated

 

no real big difference virtually the same engine except for the fact that the gearing is alittle bit better.

 

thanks...

 

better flowing exhaust manifold, cat, and catback, maybe different cams too, i dotn remember.
