Ebay RBC guy just got back to me again. i asked if he has the Larger TL04+ throttle Body

He replies:

"Sorry, I don't carry throttlebody because they haven't proven to do anything for anyone under 260whp. Yes, that's with porting the RBC to match.

I do have the RBC plastic cover, new from Honda I paid $61 for it, just for my RBC customers.

Let me know when you're ready.

Thanks,
Daniel"

So for the $280 USD i might just get that RBC and worry about the Throttle Body when Ive done Cams and stuff in the future. Make sit a cost effective mod actually.
