Alright from the get go, the skunk 2 intake manifold, fuel rail, and rdx injectors is a waste of money at this point.

The skunk 2 mani was designed for some high rpms. You will actaully lose torque because of that mani.
The rdx injectors are useless if you're not going to do any type of force induction on that a3.
And last of all, a fuel rail is just bling look. You're stock fuel rail can see up 600 hp.

I have k20a2 cams (60k) , 8 modded exhaust rockers, and a corsport vtec selonoid block off plate for sale for $250 shipped. I can send you pics of what it is.

A k20a3 vtec killer can yield 180 whp easily. There's a quite a bit of knowledge of the vtec killer setup on this site. I think Onasty on here hit 197 whp on the stock k20a3 long block.
