I'm looking into finally getting my car tuned on the dyno, and I was curious if
I should change the Intake Manifold and Exhaust (catback). Its a daily driver but I'm still looking to get the most out of my setup.

Head:
P72
ITR Valvesprings
CTR Cams
PX Inatake manifold
68mm TB
3in. SRI w/Blox V-stack and filter

Block:
Stock B20z

Exhaust:
Hytech replica header
HKS Hipower
NO catalytic converter

The exhaust I was looking at is a VRS 2.5 piping, and possible the VictorX Intake manifold.


Thanks for the response,
Joe

I say tune it with what you have. I also hear that the performer X IM is a good IM for NA, while the Victor X is more suited for turbo applications. On the stock B20z block, I would be careful not to rev the **** out of it with out help. There is a reason why the B20's and the LS blocks aren't meant to rev high due to the bigger stroke an weak rod bolts. just my 2 cents...

Yeah I know about the whole rod bolt deal its within the 200rpms of the sock limit. I've heard that the VictorX is better suited for 2.0s than the PX is.

Anyone else?

I think you should stick with the performer x (get it ported if possible) or maybe get the skunk2 pro manifold and do an intake manifold test between the two for us when you get it dynoed. The victor x is better for 2.0's than 1.8's, but you will still lose significant low and midrange power compared to the performer x. Since you're staying within 200 rpms of the stock rev limit (which is a good idea), you wont be revving high enough to really even gain any power up top from the victor x. You also mentioned it's your daily driver so most of the time I would assume you aren't revving to 7k+ rpms and you mostly stay in the low to mid rpm range so I think you would be much happier with the performer x. That's just my opinion though.

Also, if you don't mind the noise I would look into getting a 3" exhaust.

The reason I originally got it is because it was made for that power band. I guess I'll upgrade the exhaust and then hit the dyno.

Ordered my piping from VRS for $160 shipped.
