I'm sorry to have to tell you this Pitchy, but it's true. The new Si requires premium fuel.

damn that sucks.. how about ur SI is it the same thing cuz im thinkng of getting that engine next year and do the swap on my civic

On my Si (2002-2005) it's nice, because you can use regular unleaded :thumb:

what is it k20a3 u have there? i might just do that swap on my 7thgen i hear the SI engine is better then the rsx when it comes to turbo because of lower compression ratio

Yes, I have a 2002 Si with the K20a3
