Here's my setup:
2nd gen b16a
Ported and polished head
3 angle valve job
head shaved .030"
ITR intake valves
new seats, seals, pretty much freshly rebuilt head
ITR dual valve springs (ITR's in there now but also have crane dual valve springs)
Adjustable cam gears

I want to know what would be better for the street some ITR's and leave the ITR springs and retainers or my Crane stage 2 cams and matching dual valve springs, ti retainers, ferria valve keepers.
The reason i ask is because this head isn't on my b16 yet, and i am trying to decide if i should use my crane stg 2's or just get some ITR's and sell the crane stuff.
What would be better for midrange? and top end?
I also plan on going with a higher compression piston, 11:1 maybe, prolly not any higher than that as this is my daily driver. So with that in mind.

 

Buddy of mine just swapped out his CTR cams for a set of Skunk2 stage 2 cams. The CTRs beat the S2's in the low range, however the S2's made up for it in the mid to top end. I think after cams and a tune he had something like an extra 14 WHP. Although his car was had not been tuned in awhile so it prolly wasn't running at it's best with the CTR's in it. I'd say he prolly got 10-12 WHP out of the new cams.

I know it's not quite the same thing, but it gives you an idea of what to expect. Personally if I had the stage 2's on hand I'd just say **** it and put them in.

 

Not to thread jack, but what did he have done to his motor? I've heard of people saying you need a good bit of compression to fully utilize the S2S2s, like over 11.5:1. I'm cam shopping too.

 

that brings me to a good point, with a stage 2 cam is higher compression necessary to maximize the full potential of the cam.
Here's the specs on the Crane cams i have:

ctr cams made me 8 more whp on my stock b16 like them alot

 

anybody else have some input?

 

what do you mean by street? powerwise or durability?
remember that durability is compromised when using aftermarket cams.

 

i mean both powerwise and durability. This is my daily driver, i need it to get me to work and back 5 times a week.

Well he has pretty high compression (don't know #'s off the top of my head, sorry). But he's got an ITR bottom with CTR head, he's built up the bottom end and the head was the latest project.

To be honest with you I'm not quite sure wether the S2's work better with a hgih compression, but what I can tell you definitivley is that they worked very well in my friends application. He was running 0.1 faster and had a high MPH average at the track (I think he gained something like 6 MPH, little more slippage off the line perhaps?).

In any event I just wanted to give you my personal knowledge in this matter, not really guiding you in any direction just giving some unbiased info.

But like I said before, if you have the stage 2's on hand I'd use them, if not I'd find some ITRs. Just my humble opinion however.
