SR20VET build up...
So, I scored a killer deal on a VVL conversion and took the plunge. Some of you may remember my last build up, roughly a year ago if not more. I built an S14 SR20DET with the works. Tossed some rocker arms, hated life, now I don't have to worry about it. I'm still in the building process of this, I still have a lot of things I need to do/buy to get this running, but hopefully it'll be a fun project and make some pretty decent power as well. I'm utilizing a lot of my old build, so hopefully I won't be spending too much additional cash, but I'm sure that'll go to the way side...
Specs:
Stock P11 head w/ SuperTech DVS and stock cams for now...
Mazworx VVL conversion kit including IM
My old forged SR20DET bottomend
ID1000's
Bosch 044 in parallel w/ Walbro 255
GTX3076R
My old Peakboost manifold
Exedy Twin Disk
and other items as well, if they aren't mentioned they either will be or aren't important enough.
Pictures, because well everyone loves pictures....

Holy crud! Several years ago when people started using the VVL head, someone did a dyno session with stock cams and a 3076. Because the powerband basically never falls off on the big VVL lobes, it made 500whp on pump gas and 18psi at 8500rpm. Now add the GTX to that...
That parts list is exactly how I'd do it, too. How is that 044 going to run in parallel? I'd think walboro lift to a surge tank and then 044 feed would do it.

Z28- This setup previously made 491whp on a stock bottomend on pump at 18-19psi. That was with this head.
Ep- You may be talking about this setup. I bought it off a guy who had this. This kit is the prototype Mazworx produced to start selling these kits... It was installed in a blue hatch. The guy clicked off an 11.2 at 12x...

Would be really interesting to see a comparison with P11 vs P12 cams on the same setup, the P12 cams looked like they would offer a better LSA after adjusting with cam gears, of the two.

I'd like to find a set... My only concern would be valve to piston clearance, however I don't think there will be interference due to the fact that Sr20dets don't have clearance issues with 12mm of lift. I have valve reliefs too. I'm definitely down to be a test subject. I plan on getting this head flowbenched as well because I can't find solid flow numbers on them. Find me a set of P12 cams and I'll buy em for future tests.

I don't think it's going to make much difference at all. The head flows so well that you'll be up against the limits of the turbo. That's conjecture, though. It may be that the head flows so well that the cam profile has more effect. I just remember changing between huge HKS step3's and JWT's smallest C-series (C1) and only seeing 5-10hp here or there at 430whp total.
You're right... I was thinking about that test car. Here's the plot. 491whp at 8k on ROM tune.
