Hey everyone, I've got an 07 si with aem sri, vibrant headers and a skunk2 exhaust and hondata. I'm wondering what to upgrade next for a little more speed before I spend the cash to get it tuned. I'm about to change my clutch and flywheel for the exedy stock replacement, and replace my CMC because it's starting to drive me crazy but I'm undecided as to what to do next. I was thinking about skunk2 cams but idk if I want to deal with redoing the internals. Would it be less work and comparable power to just get acura cams? Also wondering if replacing the tps and pulleys are actually worthwhile? Any experiences or input is appreciated or anything I'm leaving out.

 

Your cams are pretty agressive already. The tune will create a big jump in power.

You can run aftermarket cams without redoing internals. But...changing cams on engines like the K series is a fairly involved/expensive process. Not sure how mechanically versed you are.

Pulleys won't make that big of a difference.

Simple stuff to add power would be heat shielding gaskets for the TB and intake manifold.

 

I would look at getting a better intake the SRI you have isn't getting that much power compared if you would got with a Skunk2 or HR or Ricks Spec D!

Also your header is very limiting the best bang for the buck header is the Skunk2 Alpha as for the price and the gains it's a nice bump in power.

Also look into getting RDX injectors, a J37 throttle body with p2r spacer. Get your intake port and polished that will give you a nice bump also.

Get that thing tune by someone who knows what they are doing! This will yield you a decent amount of power before you start wanting to make more.
