Well, I've been building this for the past year or so. I had a built S14 SR but threw a rocker arm, hated life, and went VVL. This is my timeline and progression on the build thus far.

The 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
Walbro 255 to surge, Bosch 044 from surge to rail
GTX3076R
My old Peakboost manifold
Exedy Twin Disk

Intake manifold and Q45 TB...


Huge intake ports...


Super clean valve train w/ Supertech DVS in the highest seat pressure available for high RPM.


Forged bottomend with VVL oil pump bolted up...


BNIB Exedy twin disc I found locally for a killer deal.


Manifold mocked up on the head, I figured out here the factory fuse/relay box were going to have to be relocated, oh well...


I overlaid my VVL intake gasket on my S14 SR gasket, its amazing how much bigger the ports are. No wonder this head flows so much better.


Lot of parts that came in to get the head bolted on to my block...


So I wanted to get the VVL head flowbenched, just to have some figures in hand and verify what I had been seeing on the web... The top numbers are the VE head and the bottom numbers are from a highport SR head.

Flow test was done on a completely stock SR20VE head. Machine used was a Superflow 600 test bench at 28" of H20 and low 80's temp.
